Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Proposed on tech-kern@.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Add Experimental ELF support for cats. Only to be used if you feel daring

Fix booting from ABLE on cats. Two problems fixed here:
1. ABLE sets the l1pt to use domain 3 for it's entries (no idea why) so to
cover all bases when setting the domain before the change to the new L1pt
become a client of all domains.
2. It seems that we setup the kernel entries without any access permission.
(note not sure that this isn't a bug) And rely on the control bits
containing either ROM or SYST enable. which allows access to pages without
access permissions set. We actually enable SYST when we do the full detect
of the CPU, but we don't detect the CPU till after the L1pt switch, which
we never make it past. Fix this by explicitly enabling the SYST bit in the
control register. rather than relying on the firmware to have dont the right
thing.

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

remove trailing \n in panic(). approved perry.

Enable caching on kernel and user page tables. This saves having
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

Do cached memory access to L1 tables, making sure to write-back the
cache after any L1 table modifications.

Overhaul how DMA ranges work in the ARM bus_dma implementation.

A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length. In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

* When manipulating vector page mappings in user pmaps, only do so if
the vector page is below KERNEL_BASE (if it's above KERNEL_BASE, the
vector page is mapped by the kernel pmap).
* Add a new function, arm32_vector_init(), which takes the virtual
address of the vector page (which MUST be valid when the function
is called) and a bitmask of vectors the kernel is going to take
over, and performs all vector page initialization, including setting
the V bit in the CPU Control register ("relocate vectors to high
address"), if necessary.

Implement pmap_growkernel for arm32 based ports.
Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats.
Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.

Pass the VA for kernel_ptpt as the VA to pmap_map_entry

Make sure the kernel_pt_table has the right physical to virtual address
mapping.

Change pmap_map_entry() to work like pmap_map_chunk(): take a pointer
to the L1 table and a virtual address, and no pointer to the L2 table.
The L2 table will be looked up by pmap_map_entry(), which will panic
if the there is no L2 table for the requested VA.

NOTE: IT IS EXTREMELY IMPORTANT THAT THE CORRECT VIRTUAL ADDRESS
BE PROVIDED TO pmap_map_entry()! Notably, the code that mapped
the kernel L2 tables into the kernel PT mapping L2 table were not
passing actual virtual addresses, but rather offsets into the range
mapped by the L2 table. I have fixed up all of these call sites,
and tested the resulting kernel on both an IQ80310 and a Shark.
Other portmasters should examine their pmap_map_entry() calls if
their new kernels fail.

Keep track of which kernel PTs are available during bootstrap,
and let pmap_map_chunk() lookup the correct one to use for the
current VA. Eliminate the "l2table" argument to pmap_map_chunk().

Add a second L2 table for mapping kernel text/data/bss on the
IQ80310 (fixes booting kernels with ramdisks).

Always pass the L1 table to pmap_map_chunk(). This allows pmap_map_chunk()
to perform some error checking.

map_chunk() -> pmap_map_chunk(), and move it to pmap.c

map_pagetable() -> pmap_link_l2pt(), and move it to pmap.c

Collapse map_entry{,ro,nc}() into a single pmap_map_entry() that
takes a prot and a "cacheable" indicator.

Rename map_section() to pmap_map_section(), move it to pmap.c, and give it
an extra argument (prot - specifies protection of the mapping).

Fix a potential boot failure, we need to make sure that the pt's used for the kernel mapping are contiguous otherwise map_chunk etc could overwrite the L1 table.

Change reference from arm32 to cats in printf, pointed out by wiz.

Move the arm32/pci files into the cats dir. AFAIK these files are only used by cats.

Overhaul of the ARM cache code. This is mostly a simplification
pass. Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:

icache_sync_all Synchronize I-cache
icache_sync_range Synchronize I-cache range

dcache_wbinv_all Write-back and Invalidate D-cache
dcache_wbinv_range Write-back and Invalidate D-cache range
dcache_inv_range Invalidate D-cache range
dcache_wb_range Write-back D-cache range

idcache_wbinv_all Write-back and Invalidate D-cache,
Invalidate I-cache
idcache_wbinv_range Write-back and Invalidate D-cache,
Invalidate I-cache range

Note: This does not yet include an overhaul of the actual asm files
that implement the primitives. Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.

Update/remove prototypes.

Following on from similair change by Jason for xscale, pass the l1 page table into the map_chunk function so it can try to map the kernel in sections.

Make GENERIC cats kernel boot again. By allocating a 2nd second level page table for the kernel and stack space we can now have to 8MB of kernel and stacks (if the kernel ever gets really bloated might need to add a 3rd!)
Also update the funcs in arm32_machdep.c that create the entries so that on cats they expect the 2 pagetables to be contiguous, note this means that for now cats is special cased in lots of funcs. I'll tidy this up to something a bit more sane soon, to avoid the multitude of #ifndef cats that I had to sprinkle in.

Finish up the changes to get LOOSE_PROTOTYPES working for cats.
Note that this leaves a few inconsistencies (no more than we already had though) eg initarm is now prototyped in arm32/machdep.h, however only cats currently makes use of that header.

Use <arm/undefined.h> instead of <machine/undefined.h>.

which pass symbol information are ready.

Rework how KERNOBJDIR functions; now it's always determined with

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

Retire "le* at pci?" from the shipped kernel configs:
- If the config had both an le@pci and a pcn, simply remove le@pci
(pcn would match at a higher priority anyway).
- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.

The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.

Remove FDDI support.

Remove HIPPI support and the esh(4) driver that uses it. There have not
been any users of HIPPI for some time, and it is unlikely to be resurrected.

Remove the strip(4) - Starmode Radio IP - pseudo-device driver. It is
long since obsolete.

branches: 1.173.4;
Enable BUFQ_PRIOCSCAN, CARP, Veriexec by default in GENERIC kernel configs.
On ports without a GENERIC kernel config enable in individul files, e.g evbmips.
Omit on:
atari, dreamcast, emips, epoc32, evbppc/VIRTEX*, ia64, luna68x, mvme68k,
mvmeppc, playstation2, riscv, sun2, sun3, x68k, zaurus due to resource
constraints or port infancy.

Add drvctl to kernel which has audio device.
audiocfg(1) requires drvctl(4).

Add ure(4) to kernel config files. Also add PHY drivers where necessary.

Remove references to "lmc" in the kernel configurations.

Retire the 'midway' driver. Discussed on tech-net@ recently and also three
years ago, part of removing the network ATM code.

Add (commented out) mue(4) to where appropriate.
Also add MII/PHY drivers for USB NICs if missing.

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

branches: 1.166.2; 1.166.4;
Alternate buffer queue strategies no longer considered experimental, update
description.

branches: 1.157.2;
Disable uscanner in all kernel configs

As discussed on current-users@, SANE uses ugen via libusb and not
uscanner, so users are not well served by having uscanner. Consensus
is that addressing how to adjust permissions for scanners should not
block restoring basic functionionality.

(Compile-tested only, but there are multiple reports of this being the
right approach.)

Remove KMEMSTATS.

branches: 1.155.2;
Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

Increase SYMTAB_SPACE (commented out).
Add commented out VERBOSE_INIT_ARM and FCOM_INIT_ARM

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.136.2;

The rnd pseudo-device is not really optional, because it is in the same

will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

branches: 1.135.2;
dependant -> dependent

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)

option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Remove the getwschar and putwschar accessops from wsdisplay drivers as

emulcookie yet they were accessops (thus having to receive an accesscookie).
Instead, just handle the WSDISPLAYIO_{GET,PUT}WSCHAR ioctls from the
driver's ioctl accessop.

As this reduces the amount of code needed to handle these operations to
two small functions in each driver, remove the WSDISPLAY_CHARFUNCS kernel
option.

turn off DEBUG and DIAGNOSTIC in GENERIC kernels so that they

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

Pare down the size of the INSTALL kernel images. This was done by:

1) Removing chio, rcmd, restore, scsictl, shutdown and slattach
from the ramdisk images
2) Removing the isp* driver from the INSTALL kernel configs
3) Reducing the memory disk and ramdisk size back from 4400 to 4200 blocks

As a result, also remove mention as QLogic ISP controllers as being
supported by the installation.

With this, the INSTALL kernel images should once again be usable;
the firmware apparently imposes a size limit around 5MB on the files
it will load.

Longer-term, this port probably ought to get it's own stand-alone boot
loader, so that it might use e.g. loadable modules.

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to

this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.

called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt

now that mem_no is emitted by config(8), there is no reason to keep

Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

+ include "dev/wsfont/files.wsfont" for VGA change.

Use new shared arm/arm32/conf.c

Move the generic arm32 files into arm/arm32 from arm32/arm32, tested kernel builds on cats and riscpc.

branches: 1.7.2;
Remove defopt EBSA285.
Move the files from footbridge that are cats specific.
Remove EBSA285 kernel as people should be able to use the generic cats kernel for EBSA285 systems.

Merge arm32/dev/bus_space_notimpl.S and hpcarm/hpcarm/bus_space_notimpl.S
into arm/arm/bus_space_notimpl.S. They were identical anyway.

This file has no excuse for being in assembler, but I'll leave that for another
day.

Add cats specific autoconf and conf.c. Also add defopt NETWINDER to files.cats, this is so a few things that include opt_netwinder compile.

Finish off the cats arch dir by creating an include dir and populating it from
arm32/include.
Make use of std.cats in the kernel config.

Fixup files.cats so it actually works.

Move blockio.S from sys/arch/arm32/arm32 to sys/arch/arm/arm, since I want to
start using it on arm26.

hpcarm gets to keep its own version, since it's not identical and I haven't
got an hpcarm box to test.

Add a files.footbridge for inclusion by cats and netwinder. This is to make moving of the footbridge dir easier (when it eventually moves from arm32)

Also remove EBSA285 defopt from the netwinder file as the netwinder isn't an eval board.

Start moving cats out of the arm32 dir into it's own arch dir.

Remove unused script

Don't need to specify OUTPUT_FORMAT/OUTPUT_ARCH.

According to matt@, .ARM.{extab,exidx} are no longer used.

Indent with 2 spaces.

branches: 1.2.6;
Put EHABI exception tables at the end of text.
provide __exidx_start and __exidx_end symbols.

branches: 1.1.2; 1.1.150; 1.1.160; 1.1.166;
Take the newly added kern.ldscript for handling ELF->a.out from jason, and
apply to the cats kernel build. Seems to work happily for me.

Apply ldscript fixes for binutils-2.39. See PR 57223.

Don't need to specify OUTPUT_FORMAT/OUTPUT_ARCH.

Simplify this by deciding load address at one place.

Indent with 2 spaces.

Kill trailing whitespaces.

branches: 1.2.124; 1.2.144;
merge ktrace-lwp.

branches: 1.1.4;
Add Experimental ELF support for cats. Only to be used if you feel daring
enough to run the ABLE firmware.

G/C ARM32_NEW_VM_LAYOUT

Switch to the generic bounce buffer support.

branches: 1.8.44; 1.8.54;
Add an arm/conf/std.arm file which contains common arm options, initially
just options CPU_IN_CKSUM.

Include std.arm in all arm platform std files.

This should reenable the asm in_cksum code for all arm platforms.

Also remove the now unused in_cksum_arm.S.

branches: 1.7.46; 1.7.50; 1.7.52; 1.7.58;
merge ktrace-lwp.

include "conf/std".

branches: 1.5.2; 1.5.18;
Don't need ARM32_PMAP_NEW option any more.

Add support for ARM32_PMAP_NEW. also make it the default for all cats
kernels.

Use the generic irq_dispatch.S

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.1.2; 1.1.8;
Start moving cats out of the arm32 dir into it's own arch dir.

This change arm, armeb, earm, earmeb, earmhf, earmhfeb so all builds that
share a MACHINE_ARCH for userland so that except for etc, will produce
identical sets.

usr/include/machine now points to usr/include/arm

Don't install fp.h anymore

branches: 1.24.2; 1.24.12;
On ARM-ish ports having PCI support, use new-style <sys/bus.h>. Do not
install <machine/bus.h>. Remove various <machine/bus.h> sources.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

branches: 1.21.20; 1.21.24; 1.21.26; 1.21.32; 1.21.38;
Merge newlock2 to head.

branches: 1.20.4;
don't install <machine/db_machdep.h>, this is kernel only

branches: 1.19.4; 1.19.8;
merge ktrace-lwp.

branches: 1.18.12;
Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.

branches: 1.17.2;
Merge the nathanw_sa branch.

Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.

cats and netwinder can share a common footbridge_intr.h file, so install and
share a common file.

Add byte_swap.h for cats, this creates the /usr/include/machine/byte_swap.h

Implement pmc(9) -- An interface to hardware performance monitoring
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.

branches: 1.12.8;
Delete <machine/psl.h> from the ARM ports. It's not a header that
we need to provide to MI code or to userland, and it's also not a
header that generic ARM code should be including directly.

Move disklabel_acorn.h to <sys/disklabel_acorn.h>, much like we did
with disklabel_mbr.h. More cleanup yet to come.

End the "new ARM includes strategy" experiment. The new strategy
broke too many assumptions makde by other parts of the source tree,
and the strategy and how it was supposed to work was never discussed
on tech-userlevel, nor was it applied consistently (to all ARM ports
and to other ports which have common MACHINE_ARCH code, such as MIPS,
m68k, powerpc).

Verified to complete a full "make build" on cats, dnard, evbarm,
and netwinder.

Remove kerndebug.h from non-Shark code (it's a Shark-specific header
file, and probably should be done away with anyway).

Kill <machine/katelib.h>. Any place that still uses it should just
reference <arm/arm32/katelib.h> until such time as all use of this
file has been purged from the face of the earth.

branches: 1.7.6;
Add a merged <pcb.h> for arm26/arm32.
