2a9f83af64 Ensure that single-frame aggregate session frames are retransmitted
with the correct configuration.

Occasionally an aggregate TX would fail and the first frame would be
retransmitted as a non-AMPDU frame.  Since bfs_aggr=1 and bfs_nframes > 1
(from the previous AMPDU attempt), the aggr completion function would be
called and be very confused about what's going on.

5ac7ffcc38 libc/amd64: Do not export .cerror.
For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit
in the FBSDprivate_1.0 version. It looks like there is no reason for this
since it is not used from other libraries. Given that it cannot be accessed
from C and its strange calling convention, it is rather unlikely that other
things rely on it. Perhaps it is from a time when symbols could not be
hidden.

Most of the amd64 assembler code jumps to .cerror using the GOT. It can jump
to it directly now, as in non-PIC mode.

There are also some minor size optimizations to instructions but they yield
virtually no benefit in the size of libc.so.7 due to padding.

b9b256e49a Remove NetBSD compat shims for drivers originally shared with NetBSD/pc98.
NetBSD/pc98 was never merged into the main NetBSD tree and is no longer
developed.  Adding locking to these drivers would have made the compat
shims hard to impossible to maintain, so remove the shims to ease
future changes.

These changes were verified by md5.  Some additional shims can be removed
that do affect the compiled results that I will probably do in another
round.

1e3510089f There is no need to release the pvh global lock around calls to

a8599e090f libc/i386: Do not export .cerror.
For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit
in the FBSDprivate_1.0 version. It looks like there is no reason for this
since it is not used from other libraries. Given that it cannot be accessed
from C and its strange calling convention, it is rather unlikely that other
things rely on it. Perhaps it is from a time when symbols could not be
hidden.

Not exporting .cerror causes it to be jumped to directly instead of via the
PLT.

This change also takes advantage of .cerror's new status by not saving and
loading %ebx before jumping to it. (Therefore, .cerror now saves and loads
%ebx itself.) Where there was a conditional jump to a jump to .cerror, the
conditional jump has been changed to jump to .cerror directly (many modern
CPUs don't do static prediction and in any case it is not much of a benefit
anyway).

This change makes libc.so.7 a few kilobytes smaller.

1832280a9e - Explicitly call twe_done() to poll the hardware when looping in
twe_start() to simulate the behavior on 4.x where the driver dropped
  spl to allow interrupts to run to free up space in the command

  one more attempt to queue the current command.  Also, when polling,
  be careful to not call twe_startio() to queue more commands to avoid
  recursion.

ef9461ba0e Add support for new Intel on-CPU Bull Mountain random number
generator, found on IvyBridge and supposedly later CPUs, accessible
with RDRAND instruction.

From the Intel whitepapers and articles about Bull Mountain, it seems
that we do not need to perform post-processing of RDRAND results, like
AES-encryption of the data with random IV and keys, which was done for
Padlock. Intel claims that sanitization is performed in hardware.

Make both Padlock and Bull Mountain random generators support code
covered by kernel config options, for the benefit of people who prefer
minimal kernels. Also add the tunables to disable hardware generator
even if detected.

_pmap_unwire_ptp() eliminates a few instructions from callers like
pmap_enter_quick_locked() where pmap_unwire_ptp()'s return value is used
directly by a conditional statement.
