fix various typos in comments and log messages.

Sync with HEAD.

Major merge to/from current.
Adds MIPS32/MIPS64 R2 support (24k, 74k, etc.) including COP0_USERLOCAL
Adds support for emulation of rdhwr $3,$29 instruction.
Major cleanup of SMP code.  (stable on multi-core / single thread per core)
llsc locking code only used in MP capable kernels.

Major merge forward from matt-nb5-mips64.
New fixup code.
New common SPL code.
New common interrupt code.
Move related variables into structures.
Cleanup locore (move MD variable into it).
Kill StudlyCaps
Use PCU for FPU

Add kernel support for MIPS TLS.  Use rdhwr rt, $29 as defined by the MIPS
TLS spec so that Linux MIPS binaries will work.  Use sysarch(MIPS_TINFOSET, v)
to set the pointer.

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Convert all the system call entry points from:
    int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Merge newlock2 to head.

Remove support for SA. Ok core@.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

quell shadow variable warnings

sync with -current

sync with head.  xen and whitespace.  xen part is not finished.

Sync with HEAD.

Hi Perry!

KNF: put "if (...)" and following statement on separate lines.

Sync with HEAD.

Don't use "int" to represent lengths; this is what size_t is for. This
does not change the ABI since we don't have 64 bit mips yet.

Sync with HEAD.

Flesh out some comments in the incomplete "smart" version of
mips_user_cacheflush().

Fix the sync with head I botched.

Sync with HEAD.

Sync with HEAD

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

__KERNEL_RCSID()

Merge the nathanw_sa branch.

#include <sys/sa.h> before <sys/syscallargs.h>, to provide sa_upcall_t
now that <sys/param.h> doesn't include <sys/sa.h>.

(Behold the Power of Ed)

Sync kqueue branch with -current.

Catch up to -current.

Inital support for Scheduler Activation on MIPS architectures.

Compiles for sgimips.  Needs more work in locore.S in order to reach
single user and beyond.

file sys_machdep.c was added on branch nathanw_sa on 2001-11-17 23:43:44 +0000

Merge the thorpej-mips-cache branch onto the trunk.  This is an
overhaul of how caches are handled for NetBSD's MIPS ports.

Update for the new cache code.  Some careful code review is needed
here, esp. by people who have done recent MIPS pmap hacking.

Sync with head (for UBC+NFS fixes, mostly).

Move prototypes for mips_user_cachectl() and mips_user_cacheflush()
to <mips/cachectl.h>.

Sync with HEAD

- fix typos in mips_user_cacheflush() and mips_user_cachectl().
- relocate those function declarations from include/pmap.h.

g/c obsolete vtrace(2) stuff

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

KNF comment.

Sync w/ -current.

Nuke register and remove trailling white space.

No need for <sys/mtio.h>

- Complete vm_offset_t purge for mips processor.
- bzero() -> memset() and bcopy() -> memcpy().
- Garbage collection in trap.c and db_interface.c.

- Step forward to MIPS64 support.  Incorporate partially Caster Fu's
patches.  Still some work is missing to satisfy his QED 5230 port.

- More symbolic definitions in genassym.cf which improve possible 64bit-ness
of locore_mips{1,3}.S.

- Fix mips3 L1 cache line size detection logic in cpuarch.h as pointed by
Caster.

- Fix a bug in proc_trampoline() code in locore_mips3.S as pointed by Caster.

- Replace vm_offset_t with vaddr_t/paddr_t entirely.  Note that
NetBSD/newsmips has purged vm_offset_t too.

- Synchronize various files according to recent changes made in main trunk.

note second parm of sysarch() is now void *, + trivial KNF, etc.

Add sys_sysarch() calls for the standard mips userspace cache-control calls.

Move the mips sys_machdep.c from pmax/pmax to mips/mips, to enforce a
common sysarch on all mips ports.

Fixes for -Wall -Wmissing-prototypes:

   Add prototypes to (most of) src/sys/arch/pmax/pmax. (The  un-protytyped
   parts still have pending merges with the Pica port.)
   Fix splx() glitches in pmax/clock.c.
   Delete old cpu/fpu identification from pmax/autoconf.c, use r4400/r4600/idt
   aware code from Pica port, now in mips/mips/mips_machdep.c.
   Delete unused multi-CPU autoconfiguration code; NetBSD/pmax does not
   support decsystem 5800s anyway.

merge in changes from 1.1 release branch

Add "sys_" prefix to the function implementing the sysarch() system call.

Include <sys/mount.h>, as the new <sys/syscallargs.h> won't compile without it.

Make system calls conform to a standard prototype and bring those
prototypes into scope.

new RCS ID format.

update for new syscall args description mechanism

bsd 4.4-lite pmax port as ported to NetBSD

upgrade to bsd 4.4-lite code base. only mod is rcsids
