Sort acpi debug values. Change "disable" to "disabled" to match rest of
the kernel. Remove debugging from acpi_toshiba since it was only used for
probe/attach.
- bzero the CCB header in getdevtree() and set the path properly, to
avoid having random garbage in the CCB header.
- if the lun isn't specified in a device specifier, it should default to
0, not whatever random data happens to be in the lun variable.
- move the prototype for getdevtree() out from under #ifndef MINIMALISTIC,
since it is used in both cases.

vm_page_free() is called. The problem with holding this lock is that it is
a spin lock and vm_page_free() may attempt the acquisition of a different
default-type lock.
for user copyinout down to 12, and keeping segments 13/14 for
kernel VA.
It would be nice to have more available, but segments lower than
this are reserved for either memory or 1:1 mapped device i/o,
and seg 15 is OpenFirmware ROM. Also, the effort to keep OpenFirmware
available for callbacks limits the use of VA-mapped segments.
Fortunately UMA_MD_SMALL_ALLOC takes away a lot of VM pressure.

include/ucontext.h
- remove trapframe and switch over to 'generic' description of machine
state. Include version field to help with future modifications.
Include floating point and altivec state, and hopefully align
correctly
powerpc/copyinout.c
- fill out casuptr() sync primitive, required by kern_umtx.c
powerpc/machdep.c
- shifted proc0/thread0/pcpu setup to before cninit, since
syscons -> make_dev -> devlock requires a valid curthread
- implemented get_mcontext/set_mcontext
- recast sendsig/sigreturn to use get/set_mcontext and new
ucontext struct. floating point now saved
- TODO: save/restore altivec state
powerpc/vm_machdep.c
- implemented cpu_thread_setup/cpu_set_upcall/cpu_set_upcall_kse
- eliminated trailing whitespace

race in between sleepq_add() and sleepq_catch_signals() in that setting
td_wchan and TDF_SINTR is not atomic to sched_lock but only to the sleepq
lock. This band-aid will stop assertion failures, but there is perhaps a
larger problem with the sleepq_add/sleepq_catch_signals race that I am not
sure how to solve. For the signals case the race is harmless because we
always call cursig() after setting TDF_SINTR. However, KSE doesn't do
anything in sleepq_catch_signals() to check that this race was lost, so I
am unsure if this race is harmful for this specific abort.
to NET_UNLOCK_GIANT(). While they are used in similar ways, the
semantics are quite different -- NET_LOCK_GIANT() and NET_UNLOCK_GIANT()
directly wrap mutex lock and unlock operations, whereas drop/pickup
special case the handling of Giant recursion. Add a comment saying
as much.
Add NET_ASSERT_GIANT(), which conditionally asserts Giant based
on the value of debug_mpsafenet.
done inside of chroot(2) to chrootdir. Added to help with sysinstall(8)
support of install to alternate root but possibly useful for setting up
jails, etc.

checking and freeing a different pointer that may or may not have been
assigned the same value. This should fix panics under load that were
recently reported.
1. Sizes in the range 1000 -- 1023 units require four characters width
for the integer; increase the field width to accomodate this.
2. Sizes in the range 9.95 -- 10 units were being displayed as "10.0"
units; adjust the logic to fix this, and now that we've got an extra
character of field width, print fractional units if the size is less
than 99.95 units.
3. Don't display sub-byte precision.
This should mean that the following sizes are displayed:
0B .. 1023B
1.0U .. 9.9U
10.0U .. 99.9U
100U .. 1023U
for values of U in "KMGTPE".
