Keyword substitution: kv
Default branch: MAIN

Define values for the 68030 TT registers in terms of the definitions
in <m68k/mmu_30.h> rather than using magic numbers.

merge pmap.h for all 4k-page motorola-MMU (or compatible) m68k platforms.

untangle includes a bit:
don't include cpu.h in pmap.h, nor cacheops.h in cpu.h.  instead,
include cpu.h and cacheops.h in just those .c files that need them.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

it really helps to get the stub right before cutting + pasting it 27 times.
alas, I did not.  doh.

add pmap_remove_all() hook (empty on most platforms so far).

Adjust whitespace so that this matches the trunk.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

MD Scheduler Activation bits for News68k.
Compile-tested only.

Catch up with -current.

Update the kqueue branch to HEAD.

file pmap.h was added on branch nathanw_sa on 2001-11-18 18:42:19 +0000

Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Reviewed by Jason.

replace vm_page_t with struct vm_page *.

replace {simple_,}lock{_data,}_t with struct {simple,}lock {,*}.

Garbage-collect pmap_page_index().

Sync with HEAD.

Undo a misguided previous change to the pmap_update() API.

Give pmap_update() an argument (a pmap_t) so that it knows which
pmap it should be updating.

#define away pmap_update() in <machine/pmap.h> so that no function
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

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.

file pmap.h was added on branch thorpej_scsipi on 2000-11-20 20:16:13 +0000

Make PMAP_PAGEIDLEZERO() return a boolean value.  FALSE indidcates
that the page being zero'd was not completed and that page zeroing
should be aborted.  This may be used by machine-dependent code doing
slow page access to reduce the latency of running a process that has
become runnable while in the middle of doing a slow page zero.

Add uvm_pageidlezero support. From x68k.

Pull up to last week's -current.

Initial import of news68k port.
