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

Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark acorn32/bus.h obsolete.

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: 1.24.20; 1.24.24; 1.24.26; 1.24.32; 1.24.38;

Finally remove the old, pre-wscons, acorn32 console code. This dated back
to RiscBSD and had been lurking in dark corners scaring people (mostly me)
for far too long. It will be missed, but not much, and I hope we can clear
up any fallout before 5.0.

While I'm in the area, also remove rpckbd(4), since pckbd(4) has
been supported on acorn32 for ages.

bootconfig.h needs reflection

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

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.

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.

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.

Clean this up, don't install files that userland doens't need.

No need to install bootconfig.h

No longer need <machine/undefined.h>.

No longer need <machine/pte.h>.

No longer need <machine/cpus.h>

Update the NetBSD part for the bootloader change. Mostly the changes in
bootconfig.h needs reflection

_important_ : the old BtRiscBSD compatibility has been put to rest... this
means that kernels from now on are not bootable by !BtRiscBSD but only with
!BtNetBSD.

Big initial commit for a new cleaned up and extended bootblock style. This
patch also allows ELF symbol tables to be read when the patches on the
bootloader are commit but will work fine with the older bootloader.

An extra option `oldkernel' will be provided in the newer bootloader to
pass out old style bootconfig's thus enabling old style kernels to load and
function.

Tested on a.out and ELF (preliminary) kernels with both older and new style
bootconfig blocks.

Clear out the vestigial support for the Simtec Hydra board. Now that we're

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.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.

It appears that MI code requires ci_cpuid to be the CPU number of the CPU
in question, whereas the ARM code was using it to hold the model
identification. To fix this, rename:

ci_cpuid -> ci_arm_cpuid
ci_cputype -> ci_arm_cputype (for consistency)
ci_cpurev -> ci_arm_cpurev (ditto)
ci_cpunum -> ci_cpuid

This makes top(1) give correct CPU numbers in its "STATE" column (all 0 for
now).

Remember the location of each CPU's idle PCB in struct cpu_info.
Move allocation of the idle PCB from hydra.c to cpu.c and add some
extra initialisation from cpu_fork().

Move curpcb into struct cpu_info in MULTIPROCESSOR kernels.

Turn curcpu() into a macro.
Rename cpu_info_array to cpu_info and make it public.
Add CPU_FOREACH() and friends.

Minimal changes to allow a kernel with "options MULTIPROCESSOR" to compile
and boot multi-user on a single-processor machine. Many of these changes
are wildly inappropriate for actual multi-processor operation, and correcting
this will be my next task.

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

merge ktrace-lwp.

Make disklabel(8) and fdisk(8) into "host tools " last step: build
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from

Remove obsolete MACHINE_ARCH -> arm32

* For platforms which are already ELF, remove the definition of
MACHINE_ARCH since <arm/param.h> already sets it correctly to "arm".
* For platforms which are not yet ELF, defined MACHINE_ARCH to "arm32"
if __ELF__ is not defined by the C preprocessor.
* In <arm/param.h>, clarify the rules about when MACHINE and
MACHINE_ARCH are defined, and to what. Also, for ELF platforms,
int the non-_KERNEL case, force both MACHINE and MACHINE_ARCH to "arm",
rather than allowing platform-specifc code to define either.

Match multiple-include-protection macros to name of file.

Roll back last change. Acorn32, being a major port, shouldn't switch to ELF
until the ABI is finalized.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

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.

Move KERNEL_VM_BASE inside where it is used (it won't be there for long).

Remove one last old pmap remnant.

Don't expose KERNEL_TEXT_BASE outside of board-specific code. This gives
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

Don't define APTE_BASE if ARM32_PMAP_NEW is defined; the new pmap
doesn't use it.

Use PAGE_SIZE rather than NBPG.

Back out previous; it breaks binary compatibility between platforms
in the same MACHINE_ARCH.

Move some #defines out of _KERNEL.

* Change all uses of KERNEL_SPACE_START to KERNEL_BASE.
* Delete now unused KERNEL_SPACE_START.

Define KERNEL_TEXT_BASE, APTE_BASE, and KERNEL_VM_BASE in terms
of KERNEL_BASE.

* Rename PROCESS_PAGE_TBLS_BASE -> PTE_BASE
* Rename ALT_PAGE_TBLS_BASE -> APTE_BASE
* Garbage-collect PAGE_TABLE_SPACE_START

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.

Move even more constants into the shared 32-bit vmparam.h header.
Cleanup elsewhere will have to be done before we can sanitize this
header any further.

- Move more contents of various <machine/vmparam.h> files into
<arm/arm32/vmparam.h> (mostly the stuff that's tied to the pmap
implementation).
- Since the MMU definitions in pte.h are specific to ARM processors
that support 32-bit mode, move pte.h to <arm/arm32/pte.h>.
- Make the Netwinder startup file build again (use PT_B|PT_C, rather
than PT_CACHEABLE, since the latter expands to a variable these days).

MAXSLP is defined to be a machine-independent scheduling parameter,
so move it into sys/param.h.

Initial commit of the splitting off of arch/acorn32 from arch/arm32.

The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.

Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.

This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.

RiscPC/A7000 have been tested and confirmed to build as should NC.

merge ktrace-lwp.

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