- 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.
clear MIPS_SR_INT_IE in struct clockframe status to prevent
unintentional spllowersoftclock(9) in hardclock(9).
This may be required because current CLKF_BASEPRI() implementation
of NetBSD/arc doesn't check ICU_MASK and all ISA devices share
the same MIPS CPU INT2 interrupt.
BTW, has anyone tried IPL_ICU_MASK on any mips ports?
so that PCI devices over ppb(4) work properly on PCI based NEC machines.
Tested on my NEC JC94 (Express5800/230) and 3Com 3C982-TXM,
which has a DEC/Intel 21154 PCI-PCI bridge and two 3C920 Ethernet chips.

OK'ed by rpaulo.
N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
an overflow occurs.
. Make this error a fatal build time error
. Move the support for dbsym into the MI Makefile.kern.inc,
conditional upon the SYMTAB_SPACE option being defined in
the kernel config file.

XXX: It seems some other mips ports (algor, evbmips, pmax, sgimips)
XXX: also have the similar problem.
in the TODO file. At least this fixes "sn0: receive buffers exhausted"
messages on my NEC-JC94.
XXX: does anyone know what "Dont reenable" comment means, which was
XXX: there since initial import of pica (not arc).
use MIPS_INT_MASK_5 and MIPS3_HARD_INT_MASK directly.
They were not used since interrupt service function was
moved from MI mips/trap.c to MD part long ago.
"XXX Maxphys temporary changed to 32K while SCSI driver is fixed."
I (and soda) don't know what the "SCSI driver" is, but add local
asc_minphys() to limit max xfer size only for asc.c for now.
- According to old asc.c driver, DMA_START() is called before NCR_CMD_DMA
command. I'm not sure which DMAC or ASC should be started first, but
move DMA command from asc_dma_go() to asc_dma_setup().
- Disable NCR_F_DMASELECT (which allows DMA xfer for select command)
since it caused some problem on PICA.
Now gxemul-0.3.6.2 reaches mountroot() sd0 (but can't exec /sbin/init yet).
- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.
(is it better to move it to kern/ or somewhere?)
- fix some obvious breakage in dev/qbus/ts.c. (not tested)
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.
OK'ed by my project mentor, William Studenmund (wrstuden@).

${TOOLDIR}/bin/${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
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
(still commented out)
- Add (also commented out) options BUFQ_PRIOCSCAN.
Suggested by perry and soda on tech-kern.
Please refer options(4) for details for these options.
-Wcast-qual differently, by instead changing the signatore of those
"functions" to take a "volatile struct timeval*" instead of a
"struct timeval*". Many places, these functions are called with
&time, and time is declared as volatile in <sys/kernel.h>. This
way we can get rid of all the ugly casts which now also triggered
warnings, and caused more code to be added to work around the
problem.
