The sample rate module currently does the slightly wrong thing when
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.

Disable trying to do HT/40 and short-GI TX.
These flags are just plain wrong - they're the node flags from negotiation,
not the configured flags. I'll jump in later on and figure out exactly
what should be done to properly set these two flags when in both STA mode
(ie, what the AP says is possible and what's configured) and AP mode
(ie, where the AP has a configuration, but then negotiates what's possible
with each node, so per-node configuration can and will differ.)
This allows the 11n 2.4ghz/ht20 mode to associate (but perform poorly still)
and exchange MCS rates with atheros reference APs and a Cisco/Linksys
E3000 AP.

Make a change to the implementation of the direct map to improve performance
on processors that support 1 GB pages. Specifically, if the end of physical
memory is not aligned to a 1 GB page boundary, then map the residual
physical memory with multiple 2 MB page mappings rather than a single 1 GB
page mapping. When a 1 GB page mapping is used for this residual memory,
access to the memory is slower than when multiple 2 MB page mappings are
used. (I suspect that the reason for this slowdown is that the TLB is
actually being loaded with 4 KB page mappings for the residual memory.)

Put in a temporary workaround for ctfmerge hanging on processing
kernel.debug (or possibly other files), when WITH_CTF is active.
This is caused by a bug in clang's integrated assembler, causing malloc
to sometimes hang during initialization in statically linked executables
that use threading, such as the copy of ctfmerge that is built during
the bootstrap stage of buildworld. The bug has been submitted upstream:
http://llvm.org/bugs/show_bug.cgi?id=9352
Note that you might have to rebuild and install libc first, to get your
kernel build to finish, because the ctfmerge binary built during
bootstrap is linked with your base system's copy of libc.a, which might
already contain a bad copy of malloc.o.
