when the bit 22 is set to 1, CPUID with EAX=0 returns a maximum
value in EAX[7..0] of 3, when set to 0(default), CPUID with EAX=0
returns the number corresponding to the maximum standard function
supported. On my machine, BIOS sets the bit to 1 to make it to be
compatible with old OS, this causes dual-core Pentium-D (two
physical cores) to be identified as hyperthreading (two logical
cores) by function mp_topology().
offset or request size which is not a multiple of the sector size, make
sure that the bio is set to indicate that no data has actually been
transferred.
The result of this is that the file offset is no longer incremented for
these requests. The fact that the file offset was incremented broke
fdisk(8)'s probing of sector size for non-512 byte sector sizes.

It is similar to debug.kdb.trap, except for it tries to cause a page fault
via a call to an invalid pointer. This can highlight differences between
a fault on data access vs. a fault on code call some CPUs might have.

the return address on the stack and only then "dereferences" %pc.
Therefore, in the case of a call to an invalid address, we arrive
to the trap handler with the invalid value in tf_eip. This used
to prevent db_backtrace() from assigning the most recent and interesting
frame on the stack to the right spot in the right function, from
which the invalid call was attempted.
Try to detect and work around that by recovering the return address
from the stack.
The work-around requires the fault address be passed to db_backtrace().
Smuggle it as tf_err.

that the first mbuf pointer in a receive socket buffer can't change
while the SB_LOCK sleepable lock is held on the socket buffer,
which is precisely what these functions do. No current protocols
invoke these functions, and removing them will help discourage them
from ever being used. I should have removed them years ago, but
lost track of it.

as possible for the syncache_add() case. The syncache timer no longer
aquires the tcpinfo lock and timeout/retransmit runs can happen in
parallel with bucket granularity.
On a P4 the additional locks cause a slight degression of 0.7% in tcp
connections per second. When IP and TCP input are deserialized and
can run in parallel this little overhead can be neglected. The syncookie
handling still leaves room for improvement and its random salts may be
moved to the syncache bucket head structures to remove the second lock
operation currently required for it. However this would be a more
involved change from the way syncookies work at the moment.
