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.

ifp is now passed explicitly to ether_demux; no need to look it up again.
Make mtag a global var in ip_input.

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.
