Most part is merged from amd64.
- i386/acpica/acpi_wakecode.S
Replaced with amd64 code (from realmode to paging enabling code).
- i386/acpica/acpi_wakeup.c
Replaced with amd64 code (except for wakeup_pagetables stuff).
- i386/include/pcb.h
- i386/i386/genassym.c
Added PCB new members (CR0, CR2, CR4, DS, ED, FS, SS, GDT, IDT, LDT
and TR) needed for suspend/resume, not for context switch.
- i386/i386/swtch.s
Added suspendctx() and resumectx().
Note that savectx() was not changed and used for suspending (while
amd64 code uses it).
BSP and AP execute the same sequence, suspendctx(), acpi_wakecode()
and resumectx() for suspend/resume (in case of UP system also).
- i386/i386/apic_vector.s

- i386/i386/mp_machdep.c
- i386/include/smp.h

vm_pager_object_lookup() already referenced the object.
Note that there is no in-tree consumers of cdev_pager_lookup(). The

Since ino_t size is about to change to 64-bits, replace ino_t used in
dump protocol definition with 32-bit dump_ino_t to preserve backward
compatibility. At some point, it may be necessary to use spare fields
in struct in order to fully support 64-bit inode numbers.

longer uses the active and inactive paging queues. Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.
Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero. However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed. The new
pmap_pv_reclaim() doesn't even try.

to freebsd-fs@, where the setfacl of an NFSv4 acl would fail.
This was caused by the VOP_ACLCHECK() call for ZFS replying
EOPNOTSUPP. After discussion with rwatson@, it was determined
that a call to VOP_ACLCHECK() before doing VOP_SETACL() is not
required. This patch fixes the problem by deleting the
VOP_ACLCHECK() call.

The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset). This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout(). This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).
8.x code:
- If the lock cannot be acquired immediately unlocks 'bar' vnode
and then locks both vnodes in order.
- wrong vnode type panics from cache_enter_time after calls by
ext2_lookup.
The fix merges the fixes from ufs/ufs_lookup.c.

add some more BAR debugging logic.
* Change the definition of ath_debug and ath_softc.sc_debug from
int to uint64_t;
* Change the relevant sysctls;
* Add a new BAR TX debugging field;
* Use this in if_ath_tx.
This has been tested by using the sysctl program, which happily allows
for fields > 32 bits to be configured.
