problem has been tracked down. This fixes the sharing of the signal
handling state: shared bits go in sigacts, per-rthread bits goes in
struct proc.

and might end up with duplicates, but that's not an issue until we're
multi-user. Change the TLB miss code to enter mappings with the right
protection ID. Properly switch pmaps on context switches. This makes the
copyins we do before starting init actually work instead of failing with
EFAULT.

scsi?" rule, similar to how ethernet PHY drivers attach at mii.

might need network (ie. nfs). Move the call to the MD boot() routines.
This cause for boot hangs diagnosed by kettenis.

__cpu_simple_lock_t - gcc most likely ignores the alignment for a stack
variable anyway. Also remove unnecessary initialisation.

for now; that is unlikely to hit some of the remaining starvation bugs.
Repair the bufpages calculation too; i386 was doing it ahead of time
(incorrectly) and then re-calculating it.

The new world order of pmemrange makes this data completely redundant
(being dealt with by the pmemrange constraints instead). Remove all code
that messes with the freelist.
While touching every caller of uvm_page_physload() anyway, add the flags
argument to all callers (all but one is 0 and that one already used
PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue
without it.
Should shrink the code a bit, as well.
matthew@ pointed out some mistakes i'd made.

Doesn't matter much since C++ ABI used by GCC doesn't mangle variable
names; however technically is required by Section 7.5 of the C++ spec.
Discussed with/OK guenther@, matthew@.

ATAPI devices. atapiscsi(4) is only for handling ATAPI devices on an
ATA bus, so umass(4) shouldn't care about it.

This header defined three thing. two of which are unused throughout the tree,
the final one was the definition of the pagq head type, move that to uvm_page.h
and nuke the header

change. It seems to have unexpected side effects, especially on MP systems,
and drahn@ disagrees with the way this change has been done and think there
is a better way to solve the original problem of msleep() fiddling with
mutex internals.

until they're zombies and then send them signals (for intr mounts). Until
that is untangled, the sigacts change is unsafe. sthen@ was the victim

are past. Use CLR() and SET() to modify necessary flags while leaving
the flags used by the buffer cache in peace.
Should make bufcache code much less confused about the state of the
bufs used in reading/writing disklabels. Other such flag abuses no
doubt await a visit.

be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves
to struct sigacts, wihle stuff that should be per rthread (ps_oldmask,
SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping
state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread
until our locking around coredumping is better.
Oh, and remove the old SunOS-compat ps_usertramp member.

using the -MD option to cc, with -MP, -MT, and -MF where needed, converting
"make depend" to a no-op. This increases parallelism for those using "make -j"
and keeps the dependencies up to date with each compilation automatically.
sparc and vax users will need to rebuild gcc with support for the
-M[PTF] options before config'ing with this diff.

whilst in the trap handler for an interrupt makes life interesting.
