- Skip the adaptive idle code when running on SMT or HTT cores. This
just wastes cpu time that could be used on a busy thread on the same
core.
- Rename CG_FLAG_THREAD to CG_FLAG_SMT to be more descriptive. Re-use
CG_FLAG_THREAD to mean SMT or HTT.

root cpuset of that jail.
Processes inside the jail will still be able to change child sets.
A superuser outside of a jail will still be able to change the jail cpuset
and thus limit the number of cpus available to the jail.

The length is supposed to be unsigned, so len - 1 < 0 won't happen except
if len == 0 anyway, and it would return 0 when it shouldn't, if len was
> INT_MAX.

This change adds (possibly redundant) early check for invalid
state input parameter (including S0). Handling of S5 request
is reduced to simply calling shutdown_nice(). As a result
control flow of acpi_EnterSleepState is somewhat simplified
and resume/backout half of the function is not executed
for S5 (soft poweroff) request and invalid state requests.
Note: it seems that shutdown_nice may act as nop when initproc
is already initialized (to grab pid of 1), but init process is in
"pre-natal" state.

Unfortunately, liblzma itself is GPLed, so unlikely to become part of
the FreeBSD base system.
However, the core lzma compression/decompression code is public
domain, so it should be feasible for someone to create a compatible
library without the GPL strings.
KAME had explicit checks at one point using it, so just hide it behind
#if 0 for now until we are sure if we can completely dump it or not.

read_support_format_raw() allows people to exploit libarchive's
automatic decompression support by simply stubbing out the
archive format handler.
The raw handler is not enabled by support_format_all(), of course.
It bids 1 on any non-empty input and always returns a single
entry named "data" with no properties set.
Fix reading big-endian binary cpio archives, and add a test.
While I'm here, add a note about Solaris ACL extension for cpio,

* Split whiny skip function to create a new best-effort skip_lenient()
* Correctly increment the top-level file position only for the top filter
* Simulate skip by reading against the current filter, not the top filter
The latter two bugs aren't currently visible because no existing
filter delegates skip operations.

w/o the overhead of decoding the raw frame. Note this also allows
drivers to record this information w/o writing the frame when the seq#

seq# is reported in a descriptor on tx done notification).

controllers may be configured as legacy IDE mode by modifying subclass and
progif without actually changing PCI device IDs. Instead of complicating
code, we always force AHCI mode while probing. Also we restore AHCI mode
while resuming per ATI/AMD register programming/requirement guides.
- Fix SB700/800 "combined" mode. Unlike SB600, this PATA controller can
combine two SATA ports and emulate one PATA channel as primary or secondary
depending on BIOS configuration. When the combined mode is disabled, this
channel disappears and it works just like SB600 PATA controller, however.
- Add more PCI device IDs for SB700/800 and adjust device descriptions.
SB800 shares the same PCI device IDs and added two more SATA IDs.
