0ac2d551f2 o Add new header <sys/stdint.h>.
o Make <stdint.h> a symbolic link to <sys/stdint.h>.
o Move most of <sys/inttypes.h> into <sys/stdint.h>, as per C99.
o Remove <sys/inttypes.h>.
o Adjust includes in sys/types.h and boot/efi/include/ia64/efibind.h
  to reflect new location of integer types in <sys/stdint.h>.
o Remove previously symbolicly linked <inttypes.h>, instead create a
  new file.
o Add MD headers <machine/_inttypes.h> from NetBSD.
o Include <sys/stdint.h> in <inttypes.h>, as required by C99; and
  include <machine/_inttypes.h> in <inttypes.h>, to fill in the
  remaining requirements for <inttypes.h>.
o Add additional integer types in <machine/ansi.h> and
  <machine/limits.h> which are included via <sys/stdint.h>.

97c97bb16b "Fix" a problem that got copied from alpha to ia64 and broke there.
When we truncate the msgbuf size because the last chunk is too small,
correctly terminate the phys_avail[] array - the VM system tests
the *end* for zero, not the start.  This leads the VM startup to
attempt to recreate a duplicate set of pages for all physical memory.

XXX the msgbuf handling is suspiciously different on i386 vs
alpha/ia64...

57d9a492bb Experiment with rewriting the syscall() wrapper using explicit bundling
and trying to reduce stalls from reading certain high latency registers.
This should be faster than the old syscall code. Its certainly a lot
smaller.

d57b94ba65 * Factor out common code for manipulating the RSE backing store.
* Implement a fairly simplistic parser for unwinding stack frames.
* Use unwind records for DDB's 'trace' command. Also add support for
  tracing past exceptions to the context which generated the exception.

The stack unwind code requires a toolchain based on binutils-2.11.2 or
later and gcc-3.0.1 or later.

cd85e2620d Small correction in the LOCAL_SAPIC structure. The Flags field
starts at offset 8; not 6. Hence the structure is 12 bytes and
not 10 bytes. Adjust the definition so that the ProcessorEnabled
flag is moved from bit 15 to bit 31 in the Flags field.

The definition now matches ACPI 2.0 Errata 1.5.

229778f87e o Do not parse the MADT as a side-effect in AcpiOsGetRootPointer,
do it as a side-effect of probing for MP hardware. This allows
   us to scan for local SAPICs early (especially before MBUF
   initialization).
o  Fix the Local SAPIC structure so that matches the Local SAPIC
   table entry. Now that the Local SAPIC info is the same as the
   Local APIC info, stop dumping the Local APIC entries.
o  For every Local SAPIC entry in the MADT that's not disabled,
   let the SMP code know about it. They represent actual CPUs.
o  Register the OS_BOOT_RENDEZ entry point and provide a (bogus)
   implementation for the entry point.
o  Provide a mapping for internal IPI numbers to ExtINT vectors.
o  In a MP system, announce the CPUs and start them by sending
   IPI_AP_WAKEUP to each of them. Not that it makes a difference
   at this time :-)
o  Miscellaneous style fixes and other adjustments.

f86214b6b8 Add APM compatibility feature to ACPI.
This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications.  The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
 - APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
 - APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
 - APMIO_GETINFO and APMIO_GETINFO_OLD
 - APMIO_GETPWSTATUS

With above, many APM applications which get batteries, ac-line
info. and transition the system into suspend/standby mode (such as
wmapm, xbatt) should work with ACPI enabled kernel (if ACPI works well :-)

8e2e767b1f Add a per-thread ucred reference for syscalls and synchronous traps from
userland.  The per thread ucred reference is immutable and thus needs no
locks to be read.  However, until all the proc locking associated with
writes to p_ucred are completed, it is still not safe to use the per-thread
reference.

45740e15b4 If we get an unhandled page fault in kernel mode, either panic (if
pcb_onfault is not set) or arrange to restart at the location in
pcb_onfault.

This ought to help the stability of a system under moderate load. It
certainly stops DDB from hanging the kernel when it tries to access a
non-present page.

1f04261973 [partially forced commit due to pilot error in earlier commit attempt]
{set,fill}_{,fp,db}regs() fixup:

 - Add dummy {set,fill}_dbregs() on architectures that don't have them.

 - KSEfy the powerpc versions (struct proc -> struct thread).

 - Some architectures had the prototypes in md_var.h, some in reg.h, and
   some in both; for consistency, move them to reg.h on all platforms.

These functions aren't really MD (the implementation is MD, but the interface
is MI), so they should move to an MI header, but I haven't figured out which
one yet.
