coherent.
- Add some missing bus_dmamap_sync() calls. This includes putting such
calls before calling reply handlers instead of calling bus_dmamap_sync()
for the request queue from individual reply handlers as these handlers
generally read back updates by the controller.

It defaults to -5 dBm for eeproms earlier than v21.
This apparently only applies to Merlin (AR9280) or later,
earlier 11n chipsets have a power table offset of 0.
All the code in ath9k which checks the power table offset
and takes it into account first ensures the chip is
Merlin or later.
The earlier way of doing debugging would evaluate the function parameters
before calling the HALDEBUG. In the case of detailed register debugging
would mean a -lot- of unneeded register IO and other stuff was going on.
This method evaluates the ath_hal_debug variable before the function
parameters are evaluated, drastically reducing the amount of overhead
enabling HAL debugging during compilation.
The reason for this is a bug at ktrops() where process dereferenced
without having a lock. This might cause a panic if ktrace was runned
with -p flag and the specified process exited between the dropping
a lock and writing sv_flags.
Since it is impossible to acquire sx lock while holding mtx switch
to use asynchronous enqueuerequest() instead of writerequest().
Rename ktr_getrequest_ne() to more understandable name [1].

which is required for RCTL. This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

- pull all rx code into t4_intr_data directly
- let go of the ingress queue lock when passing up data
- refill the freelist only if it is short of at least 32 buffers
entries instead of six). This makes "setfacl -b" do the right thing
for ACLs on ZFS. UFS recognizes both kinds of trivial ACLs; no change

* Some values changed in POSIX.1-2001; provide the former value if a program
requests compliance to an earlier version of POSIX. [1]
* Add missing _POSIX_CLOCKRES_MIN constant. This is a maximum value but
otherwise works the same as the minimum values.

determining whether to use MRR or not.
It uses the 11g protection mode when calculating 11n related stuff, rather
than checking the 11n protection mode.
Furthermore, the 11n chipsets can quite happily handle multi-rate retry w/
protection; the TX path and rate control modules need to be taught about
that.
This patch shrinks boot2 a little.
o It switches kname to be just a pointer instead of an array.
o It changes ioctl to unsigned from uint8_t.
o It changes the second keyhit limit to 3 seconds from 5.
o It removes bi_basemem/bi_extmem/bi_memsizes_valid setting.

will be.
