098aa7afca - Enable interrupts only at the end of epic_attach() when all the
other initializations succeeded.
- Initialize the TX and RX rings in epic_attach() rather than in
  epic_init() where we're not supposed to fail.  Similarly, free
  the TX and RX rings in epic_detach() rather than in epic_stop().
- Change epic_init() to be a void function now that it can't fail.
  Also change its parameter to a void * so that we have a correct
  prototype for if_init.
- Now that epic_init() has a correct prototype, don't cast the
  function pointer when initializing if_init.
- Fix nearby style bugs.

801acfe1d4 - Make sigonstack() a regular function instead of an inline and add a proc
lock assertion to it.
- SIGPENDING() no longer needs sched_lock, so only grab sched_lock to set
  the TDF_NEEDSIGCHK and TDF_ASTPENDING flags in signotify().
- Add a proc lock assertion to tdsigwakeup().
- Since we always set TDF_OLDMASK while holding the proc lock, the proc
  lock is sufficient protection to check its state in postsig() and we only
  need sched_lock when clearing the actual flag.

556bb64555 - Set the ke_cpu field in sched_add() for interrupt and realtime threads
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.

fe07eb9dfb Revise attach/detach resource cleanup
- 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).

1bc9e58dac Revert part of revision 1.97 by calling dc_stop() unconditionally
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().

29b43e58e3 MFp4(simokawa_firewire):
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.
