suspend/resume procedures are minimized among them.
common:
- Add global cpuset suspended_cpus to indicate APs are suspended/resumed.
- Remove acpi_waketag and acpi_wakemap from acpivar.h (no longer used).
- Add some variables in acpi_wakecode.S in order to minimize the difference
among amd64 and i386.
- Disable load_cr3() because now CR3 is restored in resumectx().
amd64:
- Add suspend/resume related members (such as MSR) in PCB.
- Modify savectx() for above new PCB members.
- Merge acpi_switch.S into cpu_switch.S as resumectx().
i386:
- Merge(and remove) suspendctx() into savectx() in order to match with
amd64 code.

POSIX says that SIGPIPE affects a process and therefore a SIGPIPE caused and
received by a subshell environment may or may not affect the parent shell
environment.
The change assumes that ${SH} is executed in a new process. This must be the
case if it contains a slash and everyone appears to do so anyway even though
POSIX might permit otherwise.
This change makes builtins/wait3.0 work in ksh93.
- Consistently refer to rmlocks as "read-mostly locks".
- Relate rmlocks to rwlocks rather than sx locks since they are closer to
rwlocks.
- Add a separate paragraph on sleepable read-mostly locks contrasting them
with "normal" read-mostly locks.
- The flag passed to rm_init_flags() to enable recursion for readers is
RM_RECURSE, not LO_RECURSABLE.
- Fix the description for RM_RECURSE (it allows readers to recurse, not
writers).
- Explicitly note that rm_try_rlock() honors RM_RECURSE.
- Fix some minor grammar nits.

CAM_DEBUG_CDB, CAM_DEBUG_PERIPH and CAM_DEBUG_PROBE) by default.
List of these flags can be modified with CAM_DEBUG_COMPILE kernel option.
CAMDEBUG kernel option still enables all possible debug, if not overriden.
Additional 50KB of kernel size is a good price for the ability to debug
problems without rebuilding the kernel. In case where size is important,
debugging can be compiled out by setting CAM_DEBUG_COMPILE option to 0.
Do not brelse() the buffer unconditionally with BIO_ERROR set if
uiomove() failed. The brelse() treats most buffers with BIO_ERROR as
B_INVAL, dropping their content. Instead, if the write request
covered the whole buffer, remember the cached state and brelse() with
BIO_ERROR set only if the buffer was not cached previously.
Update the buffer dirtyoff/dirtyend based on the progress recorded by
uiomove() in passed struct uio, even in the presence of
error. Otherwise, usermode could see changed data in the backed pages,
but later the buffer is destroyed without write-back.
If uiomove() failed for IO_UNIT request, try to truncate the vnode
back to the pre-write state, and rewind the progress in passed uio
accordingly, following the FFS behaviour.

until transport will do some probe actions (at least soft reset).
Make ATA/SATA SIMs to not report bogus and confusing PROTO_ATA protocol.
Make ATA/SATA transport to fill that gap by reporting protocol to SIM with
XPT_SET_TRAN_SETTINGS and patching XPT_GET_TRAN_SETTINGS results if needed.
