9ef6342f9e Check for a full virtqueue in the multiqueue transmit path
With most hosts, we'll negotiate indirect descriptors, so all we
need is one available descriptor to transmit a frame.

dd6f83a00f Avoid queue unlock followed by relock when the enable interrupt race is lost
This already happens infrequently, and the hold time is still bounded since
we defer to a taskqueue after a few tries.

43349674f1 Pull in r195679 from upstream llvm trunk:
Don't use nopl in cpus that don't support it.

  Patch by Mikulas Patocka. I added the test. I checked that for cpu names that
  gas knows about, it also doesn't generate nopl.

  The modified cpus:
  i686 - there are i686-class CPUs that don't have nopl: Via c3, Transmeta
         Crusoe, Microsoft VirtualBox - see
         https://bbs.archlinux.org/viewtopic.php?pid=775414
  k6, k6-2, k6-3, winchip-c6, winchip2 - these are 586-class CPUs
  via c3 c3-2 - see https://bugs.archlinux.org/task/19733 as a proof that
         Via c3 and c3-Nehemiah don't have nopl

bc36ff9bc7 Bad timespec_subtract() calculations produce negative tv_nsec on i386
which cause EINVAL returned from nanosleep() which cause loop in
cron_sleep() and making all cron jobs to start about 30 seconds earlier
(which cause f.e. logfiles rotation by newsyslog delayed by 1 hour).

Use simple and proved calculations from kernel's timespecsub() instead.

4b489a60e1 sh: Solve the alias recursion problem in a less hackish way.
Add the space to avoid alias recursion when the alias is expanded, not when
it is added.

As a result, displaying an alias via command -v, command -V or type no
longer erroneously appends a space. Adjust the tests so they now require
this bug to be absent.

9a5be1a0d8 dtrace: remove unexplained 16MB limitation from dt_alloc/dt_zalloc
The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
  $ dtrace -x bufsize=17m -n ...
  dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.

b65c25f54a Fix 32-bit signal handling on ppc64. This was broken when the PSL_USERSTATIC
macro was changed.  Since copying 64-bit srr1 into 32-bit srr1 drops the upper
32 bits, any bits set in the context were dropped, meaning the context check
fails.  Since 32-bit set_context can't change those bits anyway, copy the ones
from the current context (td->td_frame) before calling set_context().
