bcc0dc3dc7 Merge from POSIX.1e Capabilities development tree:
o POSIX.1e capabilities authorize overriding of VEXEC for VDIR based
  on CAP_DAC_READ_SEARCH, but of !VDIR based on CAP_DAC_EXECUTE.  Add
  appropriate conditionals to vaccess() to take that into account.
o Synchronization cap_check_xxx() -> cap_check() change.

b752fef50e o Merge recent changes from the POSIX.1e capability tree:
- Introduce cap_check_td() to reflect suser_td()
    - Introduce non-portable cap_from_text2_np(), which converts a
      text-form capability to an internal form relative to an existing
      capability, and non-portable cap_to_text2_np(), which accepts
      a flag argument specifying more about the text output format.
    - Introduce CTT_* flags controlling the behavior of
      cap_to_text2_np().

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...

3fa010222f Oops, deleted wrong BIF acquisition timeout invocation by mistake
in my previous commit.
acpi_cmbat_get_bif() from taskqueue calls acpi_cmbat_timeout() so it's
better for startup.

fc5d29ef7d o Move suser() calls in kern/ to using suser_xxx() with an explicit
credential selection, rather than reference via a thread or process
  pointer.  This is part of a gradual migration to suser() accepting
  a struct ucred instead of a struct proc, simplifying the reference
  and locking semantics of suser().

f9390180fe Some fix for the recent apm module changes.
- Now that apm loadable module can inform its existence to other kernel
   components  (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
 - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
 - Add simple arbitration mechanism for APM vs. ACPI.  This prevents
   the kernel enables both of them.
 - Remove obsolete `#ifdef DEV_APM' related code.
 - Add abstracted interface for Powermanagement operations.  Public apm(4)
   functions, such as apm_suspend(), should be replaced new interfaces.
   Currently only power_pm_suspend (successor of apm_suspend) is implemented.

ce4c60d38d Fix the ILLEGAL fdisk table that is there for supporting "dangerously
dedicated" mode.  This was specifying that there are 256 (illegal!)
heads on the disk.  If bioses store that in a byte, and it gets truncated
to 0, then that almost certainly causes the infamous divide-by-zero
nightmare.

This is also most likely the reason why the Thinkpad T20/A20 series
were locking up when FreeBSD was installed.  This is also the most likely
reason why a boot1 being present causes an IA64 box to lock up at boot.
(removing the "part4" stuff from boot1.s fixes the IA64 boxes and would
most likely have fixed the T20/A20 and some TP600E series thinkpads)
