77a6b82b27 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.

0b956d0b8b 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.

7a25d8c7ba Add event counter for zs interrupts and attach and use it; also, get the
zs major number out of the cdevsw table rather than hardcoding it in zs.c.

a85e214bda Make sure that private DMA flags don't overlap with standard DMA flags;
start these at 0x10000 to leave room for an increase in the latter.

Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

1a9f819d84 Make microtime(9) do interpolation to get better-than-hz resolution, if
the platform supplies a clkread function that does something other than
return 0 (which is the default unless overridden by the platorm code).
Supply such a function for the IP22; even if it isn't perfect, it goes
a long way to making ntp usable.

While I'm at it, move the ticks-per-hz variable out of the struct platform
since it's really private to the per-platform interrupt/clock code.

XXX: No clkread function supplied for IP32, since it has other problems --
like a hardcoded ticks-per-hz, but the same code as on the IP22 could be
used.

7f5269c58f NetBSD Disklabel and SGI Volume header support. Based on NetBSD/mipsco
due to its similarities.

Patch has been tested by many people on the sgimips list for some time with
no complaints.

e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.

6d6ab09e29 Initial boot device determination code: makebootdev() to parse boot command
line parameters, and device_register() to try to match the boot device.  Works

SCSI adapters.

a8bb9b127a All soft interrupts are currently handled by soft interrupt 1, so make
all splsoftxxx() calls block soft interrupt 1 and make spllowersoftclock()
re-enable soft interrupt 1.

XXX: This needs to be reworked so that spllowersoftclock() only turns on
softclock interrupts, not all soft interrupt.  That change is coming soon.
