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.

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.

Make these closer to working.

Rename arc_trap.c to interrupt.c, which derived from ancient pica_trap.c
but currently contains only interrupt stuff. Ok'ed by soda.

Implement separate statclock(9) handler which uses the MIPS3 CPU INT5
internal timer compare register. Based on hp300 and arm implementation.

This is enabled by options ENABLE_INT5_STATCLOCK, but disabled by default.

Misc minor cleanup for arc interrupt handlers:
- always enable options MIPS3_ENABLE_CLOCK_INTR and just clear the compare
register in cpu_intr() to make CLKF_BASE() works
properly
- prepare only possible number of cpu_inttab
- use macro for interrupt priority number passed to arc_set_intr()
to avoid confusion
- merge arc_hardware_intr() into cpu_intr()
- check independent timer interrupt first in cpu_intr()
- tweak MIPS_SR_INT_IE before calling hardclock timer handlers so that
spllowersoftclock(9) will be invoked properly in hardclock(9)
- reenable interrupt for timer in cpu_intr() rather than each timer handlers

okay'ed by soda.

Note the real fix is to make CLKF_BASE() check all independent
interrupt sources including jazz and isa devices.

Fix typo and a function name in panic message.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

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.

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
* Added definitions for the Master Boot Record (MBR) used by
a variety of systems (primarily i386), including the format
of the BIOS Parameter Block (BPB).
This information was cribbed from a variety of sources
including <sys/disklabel_mbr.h> which this is a superset of.

As part of this, some data structure elements and #defines
were renamed to be more "namespace friendly" and consistent
with other bootblocks and MBR documentation.
Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
* Deprecated in favor of <sys/bootblock.h> (the latter is more
"host tool" friendly).

amd64 & i386:
* Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
be consistent with the naming convention of the msdosfs tools.

* Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
and it's confusing to have two functionally equivalent bootblocks,
especially given that "ufs" has multiple meanings (it could be
a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

* Rework pbr.S (the first sector of bootxx_*):
+ Ensure that BPB (bytes 11..89) and the partition table
(bytes 446..509) do not contain code.
+ Add support for booting from FAT partitions if BOOT_FROM_FAT
is defined. (Only set for bootxx_msdos).
+ Remove "dummy" partition 3; if people want to installboot(8)
these to the start of the disk they can use fdisk(8) to
create a real MBR partition table...
+ Compile with TERSE_ERROR so it fits because of the above.
Whilst this is less user friendly, I feel it's important
to have a valid partition table and BPB in the MBR/PBR.

* Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
with other platforms.

* Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
we can boot off FAT partitions.

* Crank version of /usr/mdec/boot to 3.1, and fix some of the other
entries in the version file.

installboot(8) (i386):
* Read the existing MBR of the filesystem and retain the BIOS
Parameter Block (BPB) in bytes 11..89 and the MBR partition
table in bytes 446..509. (Previously installboot(8) would
trash those two sections of the MBR.)

mbrlabel(8):
* Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

rather than assigning to the whole field, set or clear individual flags,

which is the purpose of all this.

Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those

backout previous kprintf change

merge mips and pica locore.S, pass 0:
* cut-and-paste all the code for both r2000 (MIPS-I) and r4000 (MIPS-III)
into both the pica and pmax locore.S.

* Change the names of the small segments of vector code that are
bcopied to the machine vector locations, to avoid clashing.
Get rid of the Sprite MachXXX names for the vector code, and
use use mips_r2000_xxx and mips_r4000_xxx instead.

Update the names used in the vector-copying code and trap handlers
to match.

* Most of the rest of the pica locore.S was copied from the pmax
locore.S, and then edited to work on an r4000. The names of
functions and of manifest constants stayed the same, although
both assmbler code and constant values changed.
cut-and-paste such code into contiguous blocks protected by
#if / #endif. Much of the cache and trap-handling code
needs r3000-only register fields, on the r3000, and r4000-only
insns and registers on the r4000.

* change the pmax r2000 exception-handling code to extract a trap
code with the user/kernel bit at 0x20 rather than 0x10.
(r2000s have 4-bit execption codes, r4000s have 5-bit.)
Use the a 16 from-user-space + 16-from-kernel space jump table,
just like on the r4000 pica port.

* add NOPs to the common code where required by the r4000 pipeline
constraints.
* add _C_LABEL() macros to the r4000 locore.

Comitted to provide a snapshot for others to test, and work on a cleaner merge.

Update Pica machdep.c and locore.S to work with new, "merged" machdep.h:

* Add a MIPS-I (r3000) exception handler to the Pica locore.S.
Change the names of the masks used to extract the exception code
to the new MIPS_xxx names.
* Rename the vector code from MachException() to
mips_r4000_exception, in both locore and in the init_main()
code that copies it from locore to the exception vector locations.

* Change the locore and C code to use the new MIPS_SR_INT_IE
name for the Status register master interrupt-enable bit.

Similar changes to the pmax equivalents are in progress.

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.

Replace the traditional buffer memory management -- based on fixed per buffer
virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.

This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms. Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.

On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.
