-O2 build. I'm unsure what changed recently to reveal this error since
this code has been unchanged for months.
switch to. If a non-NULL thread pointer is passed in, then the CPU will
switch to that thread directly rather than calling choosethread() to pick
a thread to choose to.
- Make sched_switch() aware of idle threads and know to do
TD_SET_CAN_RUN() instead of sticking them on the run queue rather than
requiring all callers of mi_switch() to know to do this if they can be
called from an idlethread.
- Move constants for arguments to mi_switch() and thread_single() out of
the middle of the function prototypes and up above into their own
section.
following drivers: bfe(4), em(4), fxp(4), lnc(4), tun(4), de(4) rl(4),
sis(4) and xl(4)
More patches are pending on: http://peoples.freebsd.org/~mlaier/ Please take
a look and tell me if "your" driver is missing, so I can fix this.

lock and sched_lock so they can be read with either lock held. Document
the locking as well. The one remaining bogosity is that pr_addr and
pr_ticks should be per-thread but profiling of multithreaded apps is
currently undefined.
stats structure and a vmspace as this should always be true rather
than checking the always true condition in an if statement.
- Remove never-false check: if ((ru = &pstats->p_ru) != NULL)
- Remove pstats variable that is only used once and inline its one use
instead.
Just use p2->p_uarea directly instead.
- Remove an old and mostly bogus assertion regarding p2->p_sigacts.
- Use RANGEOF macro ala fork1() to clean up bzero/bcopy of p_stats.
pointer to the corresponding struct thread to the thread ID (lwpid_t)
assigned to that thread. The primary reason for this change is that
libthr now internally uses the same ID as the debugger and the kernel
when referencing to a kernel thread. This allows us to implement the
support for debugging without additional translations and/or mappings.
To preserve the ABI, the 1:1 threading syscalls, including the umtx
locking API have not been changed to work on a lwpid_t. Instead the
1:1 threading syscalls operate on long and the umtx locking API has
not been changed except for the contested bit. Previously this was
the least significant bit. Now it's the most significant bit. Since
the contested bit should not be tested by userland, this change is
not expected to be visible. Just to be sure, UMTX_CONTESTED has been
removed from <sys/umtx.h>.

faster and iterate to over its work list a few times in an attempt
to empty the work list before the syncer terminates. This leaves
fewer dirty blocks to be written at the "syncing disks" stage and
keeps the the "giving up on N buffers" problem from being triggered
by the presence of a large soft updates work list at system shutdown
time. The downside is that the syncer takes noticeably longer to
terminate.

Fix this problem by separating out the SACK and the newreno cases. Also, check
if we are in FASTRECOVERY for the sack case and if so, turn off dupacks.
Fix an issue where the congestion window was not being incremented by ssthresh.
Thanks to Mohan Srinivasan for finding this problem.

bus interfaces. These interfaces use the FTDI chipset with different
Vendor and Product IDs.
Add two additional baud rate enumerations. The vehicle bus interfaces
use a baud rate of 2000000. Also add 3000000 as it is the other FTDI
baud divisor special case.
I've commited a slightly different patch from that provided in the PR as
I changed the matching code a bit yesterday.

Pointy hat to: imp for breaking the build on so many platforms.
