on the previous generation of Pentium-M processors (Banias). Support for
Dothan and later processors involves working with acpi_perf(4) to extract
information about supported states. This driver should work on MP systems
including HTT. It is experimental and may have a few bugs but has been
tested to not crash at least.
Thanks to Colin Percival for his initial work on this driver.

the rest, which do check the flag.

very slow process, especially for large file systems that is just
recovered from a crash.
Since the summary is already re-sync'ed every 30 second, we will
not lag behind too much after a crash. With this consideration
in mind, it is more reasonable to transfer the responsibility to
background fsck, to reduce the delay after a crash.
Add a new sysctl variable, vfs.ffs.compute_summary_at_mount, to
control this behavior. When set to nonzero, we will get the
"old" behavior, that the summary is computed immediately at mount
time.
Add five new sysctl variables to adjust ndir, nbfree, nifree,
nffree and numclusters respectively. Teach fsck_ffs about these
API, however, intentionally not to check the existence, since
kernels without these sysctls must have recomputed the summary
and hence no adjustments are necessary.
This change has eliminated the usual tens of minutes of delay of
mounting large dirty volumes.

preliminary support for using the GCC-compatibility of ICC was committed
but couldn't be tested at that time due to problems with ICC itself. Since
ICC 8.1 it's possible to use its GCC-compatibility under FreeBSD and it
turned out that a typedef for __gnuc_va_list is required in that case.
Revert the part of rev. 1.8 which #ifdef'ed out __gnuc_va_list for ICC.

patch from kan@).
Pull bufobj_invalbuf() out of vinvalbuf() and make g_vfs call it on
close. This is not yet a generally safe function, but for this very
specific use it is safe. This solves the problem with buffers not
being flushed by unmount or after failed mount attempts.
a packet has VLAN mbuf tag attached. This is faster to check than
m_tag_locate(), and allows us to use the tags in non-vlan(4) VLAN
producers.
The first argument to VLAN_OUTPUT_TAG() is now unused but retained
for backward compatibility.
While here, embellish a fix in rev. 1.174 of if_ethersubr.c -- it
now checks for packets with VLAN (mbuf) tags, and it should now
be possible to bridge(4) on vlan(4)'s whose parent interfaces
support VLAN decapsulation in hardware.
