Enumerate logical hyperthread CPUs manually if they aren't already listed
in the mptable. The way this works is that we determine if the system
has hyperthreading and how many logical CPU's should be in each physical
CPU by using the information returned by cpuid. During the first pass of
the mptable, we build a bitmask of the APIC IDs of the CPUs listed in the
mptable. We then scan that bitmask to see if the CPUs are already listed
by the mptable, or if there are any APIC IDs already in use that would
conflict with the APIC IDs of the logical CPUs. If that test succeeds,
then we fixup the count of application processors. Later on during the
second pass of the mptable we create fake processor entries for logical
CPUs and add them to the system.
We only need this type of fixup hack when using the mptable to enumerate
CPUs. The ACPI MADT table properly enumerates all logical CPUs.

If the boot processor supports hyperthreading and contains more than one

Move the MOD_SHUTDOWN event from shutdown_post_sync to shutdown_final,
so that entities that want to use the post_sync hook to write stuff
to devices and other tidy-up can do so before the device tree is
shot down. eg: da doing a SYNC_CACHE etc. This should get crashdumps
working on mpt devices again, and stops the ia64 boxes locking up
on regular shutdown when da tries to issue the scsi commands to mpt.

This patch fixes a problem caused by applications that rapidly and
repeatedly truncate the same file. Each time the file is truncated,
a buffer is grabbed to store the indirect block numbers that need
to be freed. Those blocks cannot be freed until the inode claiming
them is written to disk. Thus, the number of buffers being held by
soft updates explodes and in extreme cases can run the kernel out
of buffers. The problem can be avoided by doing an fsync on the
file every debug.maxindirdep truncates (currently defaulted to 50).
The fsync causes the inode to be written so that the held buffers
can be freed. The check for excessive buffers is checked as part
of the existing hook for excessive dependencies (softdep_slowdown)
in the truncate code.

Cast the integer read as the first argument for %b to an unsigned integer

Don't reference the maxlen and flags fields in the ring control blocks
as separate 16-bit entities. Some of the ring control blocks are
in NIC memory, so they must be referenced using 32-bit accesses.
Smaller accesses have been observed to fail under some conditions.
This caused the rings to be set up wrong, leading to writes by the
card outside of the intended bounds of the rings. This problem was
diagnosed by Michael Barthelow. Don Bowman submitted a patch which
fixed the problem using a slightly different approach.

BSD disklabels expose the controling label though the 'c' partition, and
some trick is necessary to prevent further BSD geoms from attaching to
that. Our old trick was to make sure we don't attach to a geom from

this fact. Instead, calculate the MD5 checksum of the label we target
