paths are reflexive. It is now possible to fail part-way through a
suspend sequence, and recover along the resume code path.
Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used
after hibernate (and suspend too) to finish the job. Some drivers
must be converted at the same time to use this instead of shutdown hooks
(the others will follow at a later time)

an MI file, <sys/syscall_mi.h>, correcting inconsistencies and the
handling when copyin() of arguments fails.
Tested on i386, amd64, sparc64, and alpha (thanks naddy@)
Any issues with other platforms will be fixed in tree.

MI float.h which pulls in and defines the values that are needed from
there, and repair sys/limits.h so that it defines the values it needs
as well (depending on POSIX version, XPG version, etc). guenther has
a more exact selection of that coming for limits.h.
this also fixes a few mistakes for the vax.

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.

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.

a vforked child behave correctly. Have the parent in a vfork()
wait on a (different) flag in *its* process instead of the child
to prevent a possible use-after-free. When ktracing the child
return from a fork, call it rfork if an rthread was created.

a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument].
This allows MI drivers to implement mmap() routines without having to know
about the pmap_phys_address() implementation and #ifdef obfuscation.

vaddr_t PMAP_PREFER(..., vaddr_t). This allows better compiler optimization
when the function is inlined, and avoids accessing memory on architectures
when we can pass function arguments in registers.

early MD and late MI files must be split up so that vers.o can sneak
between. Issue spotted by bluhm, repair discussed with miod

having it linked last is bad (on at least i386 and amd64) because the lapic
is mapped over the start of the data segment -- savecore(8) then reads the
version string for a fixed buffer space, and reads into the lapic area
causing unintended side-effects (at least on Intel X5570 and X5680)

the differences between these files. You will need a newer config(8) binary

ok kettenis miod

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.
