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.

Per lengthy discussion with Andrew Brown.

branches: 1.2.36;
Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Add optoion GENERIC.local include to the end of ~all GENERIC configs

This excludes atari, sgimips, evbmips, evbppc, evbsh3, and hpcarm
all of which have somewhat specific kernel config file layouts

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART

as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr

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.

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.

These boards are available with a dazzling array of build options. At

o The VMEchip2 must be present,
o If offboard VMEbus RAM is not present, at least 8MB of onboard
RAM is required.
o Even if offboard VMEbus RAM *is* present, at least 4MB of onboard
RAM is required. (Boards with 1 or 2MB onboard RAM *can* be

Switch mvme68k to the common m68k vector table.

Remove duplicated / slightly-tweaked loadustp() (load user segment table)

Improve kgdb build for mvme68k:

* cast second kgdb_trap argument to (db_regs_t *).
* build m68k/kgdb_machdep.c in kgdb enable build for kgdb_trap() implementation.

KGDB build still fails, apparently due to missing zs_kgdb.c implementation.

Refactor the 68040 writeback() from each m68k port's trap handler into a

from the mvme68k port.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

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.

Ditch the `simulated' software interrupt in favour of

This greatly simplifies the `rei' path and allows
interrupt nesting to be tracked somewhat more easily.

As a result we now have a working CLKF_INTR() macro
and can detect uvm_fault() being called from an interrupt
(although there may still be a very short race detecting
the latter; need to investigate further).

Add an e_trapsignal member to struct emul, so that emulated processes can

Add preliminary support for the MVME162-LX 200/300 series of boards.

Currently, the major onboard devices are supported (disk, network,
rs232 and VMEbus). However, work is still need to support the remaining
devices (eg. IndustryPack sites).

These boards are available with a dazzling array of build options. At
this time, the following options are *required*:

o Real floating point hardware (the 68LC040 model isn't tested),
o The VMEchip2 must be present,
o If offboard VMEbus RAM is not present, at least 8MB of onboard
RAM is required.
o Even if offboard VMEbus RAM *is* present, at least 4MB of onboard
RAM is required. (Boards with 1 or 2MB onboard RAM *can* be
supported with offboard RAM, but not without some funky values in
the VMEbus Master mapping registers.)

There is no support for boards other than those in the -LX 200/300 series.

Initial revision

mark nsmb major obsolete

Systematize handling of removed drivers.

- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.

Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.

Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)
