a process group.
- Call pgadjustjobc() twice in fixjobc() to avoid code duplication and
improve readability.
- Use the proc lock to protect P_SHOULDSTOP() instead of sched_lock.
- Check to see if a process is PRS_NEW with sched_lock before trying to
lock its proc lock since the lock may not be constructed yet.
since they are going on the current cpu and not their previously assigned
cpu.
- sched_runnable() should only return true in the SMP case if the other
processor has more than one thread that is runnable. We can not steal
curthread.
- Change kseq_print() to accept the cpuid instead of a kseq pointer. This
makes use of this function in ddb much easier.
the process and session. Instead, cache a true reference to the session
when we do the hold and release our reference on that session. This avoids
the need for the proc lock when dropping the reference.
protects, so don't bother locking it while we assign it to a ucred's

- Fully construct the new credential for a process before assigning it to
p_ucred.
- Set p_acflag earlier while already hold the proc lock in fork1().
- Mark the realitexpire() callout MPSAFE for new processes. It was already
marked safe for proc0 a long while ago.
printed out needs a prefix such as when a thread is blocked on a lock.
- Use another local variable to close another race for the td_wmesg and
td_wchan members of struct thread.
- Unconditionally call *_stop() if device is in the tree. This is to
prevent callouts from happening after the device is gone. Checks for
bus_child_present() should be added in the future to keep from touching
potentially non-existent hardware in *_detach(). Found by iedowse@.
- Always check for and free miibus children, even if the device is not in
the tree since some failure cases could have gotten here.
- Call ether_ifdetach() in the irq setup failure case
- ti(4), xl(4): move ifmedia_init() calls to the beginning of attach so
that ifmedia_removeall() can be unconditionally called on detach. There
is no way to detect whether ifmedia has been initialized without using
a separate variable (as tl(4) does).
- Add comments to indicate assumptions of code path
bytes_in_mbuf rather than MCLBYTES. Add the ethertnet header to the

in dc_detach() instead of only calling it if the hardware is preset.
This is a workaround for page faults in softclock() after a `dc'
device was detached, caused by not disabling a timer before freeing
its memory. The bus_child_present() checks should probably be
re-added later, but only to avoid the hardware accesses and not the
other resource cleanups in dc_stop().

Many internal structure changes for the FireWire driver.
- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE.
- AR buffer handling.
Don't reallocate AR buffer but just recycle it.
Don't malloc and copy per packet in fwohci_arcv().
Pass packet to fw_rcv() using iovec.
Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode. We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
not cycle master capable but set myself for root node.
We should be the root node after next bus reset.

blocking allocation could occur as a result of a label
initialization. This will simulate the behavior of allocated
label policies such as MLS and Biba when running mac_test from
the perspective of WITNESS lock and sleep warnings.

because these bits should have been set earlier in the process. In
the future, we'll only set these bits when the driver requests the
resource, not when the bus code detects the resource.
