1acd03e35e Wait until completion context unwinds before retrying CCBs that have been
queued internally.  This works around issue in the isci HAL where it cannot
accept new I/O to a device after a resetting->ready state transition until
the completion context has unwound.

This issue was found by submitting non-tagged CCBs through pass(4) interface
to a SATA disk with an extremely small timeout value (5ms).  This would trigger
internal resets with I/O in the isci(4) internal queues.

The small timeout value had not been intentional (and original reporter has
since changed his test to use 5sec instead), but it did uncover this corner
case that would result in a hung disk.

e5f61c6580 Call bpf_jitter() before acquiring BPF global lock due to malloc() being used inside bpf_jitter.
Eliminate bpf_buffer_alloc() and allocate BPF buffers on descriptor creation and BIOCSBLEN ioctl.
This permits us not to allocate buffers inside bpf_attachd() which is protected by global lock.

34ec5c8650 Fix old panic when BPF consumer attaches to destroying interface.
'flags' field is added to the end of bpf_if structure. Currently the only
flag is BPFIF_FLAG_DYING which is set on bpf detach and checked by bpf_attachd()
Problem can be easily triggered on SMP stable/[89] by the following command (sort of):
'while true; do ifconfig vlan222 create vlan 222 vlandev em0 up ; tcpdump -pi vlan222 & ; ifconfig vlan222 destroy ; done'

Fix possible use-after-free when BPF detaches itself from interface, freeing bpf_bif memory,
while interface is still UP and there can be routes via this interface.
Freeing is now delayed till ifnet_departure_event is received via eventhandler(9) api.

Convert bpfd rwlock back to mutex due lack of performance gain (currently checking if packet
matches filter is done without holding bpfd lock and we have to acquire write lock if packet matches)

d9369891ab Another minor re-arrangement of the code: calcualte the master clock
frequency in the at91_pmc_clock_init rather than passing it in.  Allow
for frequencies >= 21MHz by rounding to the nearest 500Hz (Idea from
Ian Lapore whose company uses a similar arrangement in their product).
at91_pmc_clock_init() is now nearly independent of the rest of the pmc
driver (which means we may be able to call it much earlier in boot
soon to eliminate the master clock config file requirement for printf
to work during early boot and also eliminate some interdependencies
with the device ordering which requires pmc to be the first device
added).

b52bde70e4 Replace all uses of the vm page queues lock by a r/w lock that is private
to this pmap.c.  This new r/w lock is used primarily to synchronize access
to the PV lists.  However, it will be used in a somewhat unconventional
way.  As finer-grained PV list locking is added to each of the pmap
functions that acquire this r/w lock, its acquisition will be changed from
write to read, enabling concurrent execution of the pmap functions with
finer-grained locking.

e6804cafc0 Determine kernel load address dynamically from u-boot memory map.
The generic ELF loading code maps the kernel into low memory
by subtracting KERN_BASE.  So the copyin/copyout/readin functions
are always called with low addresses.  This code finds the largest
DRAM block from the U-Boot memory map and adds that base to
the addresses.

In particular, this fixes ubldr on AM3358, which has DRAM
mapped to 0x80000000 at power-on.

e83623fb1f Replace the list of PVOs owned by each PMAP with an RB tree. This simplifies
range operations like pmap_remove() and pmap_protect() as well as allowing
simple operations like pmap_extract() not to involve any global state.
This substantially reduces lock coverages for the global table lock and
improves concurrency.

b8d578077a Rewrite nd6_sysctl_{d,p}rlist() to avoid misaligned accesses to char arrays
casted to structs by getting rid of these buffers entirely. In r169832, it
was tried to paper over this issue by 32-bit aligning the buffers. Depending
on compiler optimizations that still was insufficient for 64-bit architectures
with strong alignment requirements though.
While at it, add comments regarding the total lack of locking in this area.

* ath_start() shouldn't be private, but it's called as part of
  the RX path. I should likely migrate ath_rx_tasklet() back into
  if_ath.c and then return this to be 'static'.  The RX code really
  shouldn't need to see TX routines (and vice versa.)

* ath_beacon_* should be in if_ath_beacon.[ch].
