call, which assumes the hardware is awake.
Turn ath_update_mcast() into a routine that's only called from the
net80211 layer - and it forces the hardware awake first.
This fixes a LOR from the EDMA RX path which calls ath_mode_init()
with the RX lock held - the driver lock can't also be grabbed.
This path assumes that the ath_mode_init() callers all wake up
the NIC first.
Tested:
* AR9485, STA mode, powersave
This seems to probe/attach as an AR9485 and thus nothing else besides
adding the device id seems to be required.

mixing on stack memory and UMA memory in one linked list.
Thus, rewrite TCP reassembly code in terms of memory usage. The
algorithm remains unchanged.
We actually do not need extra memory to build a reassembly queue.
Arriving mbufs are always packet header mbufs. So we got the length
of data as pkthdr.len. We got m_nextpkt for linkage. And we need
only one pointer to point at the tcphdr, use PH_loc for that.
In tcpcb the t_segq fields becomes mbuf pointer. The t_segqlen
field now counts not packets, but bytes in the queue. This gives
us more precision when comparing to socket buffer limits.

freebsd-current. These CPU speed control techniques are usually unhelpful
at best. For now, continue building the relevant code into GENERIC so that
it can trivially be re-enabled at runtime if anyone wants it.

from the zio_vdev_io_start stage and hence don't suspend and complete

This prevents double fault panic on slow machines running ZFS on

sys/systm.h must always come after sys/param.h.
Remove sys/types.h which should never be included together with sys/param.h.
Add sys/malloc.h for correctness even if it seems to don't be needed.
Remove more unused headers found by unusedinc (from bde@) and tested with a

disk. That has a side effect of corrupting the "." entries names on
rename, since the call to createde() in the msdosfs_rename() sets the
de_Name to the target name. If any change to the directory attributes
is performed, the wrong name is written back to the on-disk direntry
on update.
Overwrite the de_Name for the directories on rename to correct the dot
name.
