timeout
the semantics of 'timeout' parameter differ to POSIX for the syscall
(not const, may be modified by kernel if interrupted from the wait) -
libc will provide appropriate wrapper
since sigwaitinfo(2) will be implemented as wrapper around sigtimedwait()
too, remove it's reserved slot and move sigqueue slot 'up', freeing
slot #246
It will never get back... it will not be found in nfs_nget, a new
nfsnode+vnode is allocated instead, which causes a node leak, and
also makes the mountpointness of the vnode to be forgotten, breaking
filesystem crossing lookups through this vnode.

as (G)uarded, protecting it from the processor being too aggressive in
reordering and prefetching. This allows OFB_ENABLE_CACHE to work on my
Powerbook G4.
Thanks to matt@ for suggesting this fix. "It's the right thing to do."
such as Makefile.in are ``out of date'' and ``helpfully'' attempt to
update them with autoconf, autoheader, or automake.
Fixes some toolchain PRs, and my sanity.
compile-time by BRIDGE_IPF, and at runtime by brconfig with the {ipf,-ipf}
option on a per-bridge basis.
As a side-effect, add PFIL_HOOKS processing to if_bridge.
assume that the few leading pages in front of the kernel image are
always present.
Adjust `va2pa_offset' on sun4 and sun4c as well, so that some day we can
have the bootstrap program load the kernel some place else.
(XXX sa_yieldcall() and sa_switchcall() should be combined and take
arg as the function to call, but I'm somewhat nervous about void *
vs. void (*)()).
we read-lock the map and call uvm_map_lookup_entry() instead of simply
walking from the header to the next and to the next, etc.
Dumping from sparsely populated amaps could cause faults that would
result in amaps being split, which (in turn) resulted in the core
dumping routines dumping some regions of memory twice. This makes the
core file too large, the headers not match, gdb not work properly,
and so on.

acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
in acpi_eval_string()/acpi_eval_struct().
Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.
