09ae596bf6 Fix race in interrupt handling that could cause IO to hang up under heavy
load.

c82bcdb25e There is no reason to do i+dcache writeback and invalidate when changing
the translation table (this may be left over from armv5 days).  It's
especially bad to do so using a cache operation that isn't coherent on
SMP systems.

0ccab3af38 A lot of current code in network stack expects mbufs not having
m_nextpkt pointer, assuming that if there is one, then this is
a packet batch. Thus, mbufq_dequeue() needs to clear it on mbuf
that is being returned.

e9b70483d1 soreceive_generic() still has similar KASSERT(), therefore instead of
remove KASSERT(), change it to check mbuf isn't NULL.

f21684bc75 In some cases soreceive_dgram() can return no data, but has control
message. This can happen when application is sending packets too big
for the path MTU and recvmsg() will return zero (indicating no data)
but there will be a cmsghdr with cmsg_type set to IPV6_PATHMTU.
Remove KASSERT() which does NULL pointer dereference in such case.
Also call m_freem() only when m isn't NULL.

35f612b88a Kernel support for the Vector-Scalar eXtension (VSX) found on the POWER7
and POWER8. This instruction set unifies the 32 64-bit scalar floating
point registers with the 32 128-bit vector registers into a single bank
of 64 128-bit registers. Kernel support mostly amounts to saving and
restoring the wider version of the floating point registers and making
sure that both scalar FP and vector registers are enabled once a VSX
instruction is executed. get_mcontext() and friends currently cannot
see the high bits, which will require a little more work.

As the system compiler (GCC 4.2) does not support VSX, making use of this
from userland requires either newer GCC or clang.

To delay packets from a particular TX queue by a particular time, write a value
into the TX Pace table s.t. pace time <= TX Pace Clock Period * (2 ^ pace value)
- the TX pace clock is 1/13 of the system clock, so its period should be 104 or

a6d980a99e Pull in r230058 from upstream llvm trunk (by Benjamin Kramer):
LoopRotate: When reconstructing loop simplify form don't split edges
  from indirectbrs.

  Yet another chapter in the endless story. While this looks like we
  leave the loop in a non-canonical state this replicates the logic in
  LoopSimplify so it doesn't diverge from the canonical form in any way.

  http://llvm.org/PR21968

This fixes a "Cannot split critical edge from IndirectBrInst" assertion
failure when building the devel/radare2 port.

9cb8ba562b Step 2 of eliminating the "games" distribution: Remove punch card
utilities.

I was originally planning on removing the phase-of-moon (pom), clock
(grdc), and caesar cipher (caesar, rot13) utilities as well, but after
I committed r278616 I received an astonishing volume of email informing
me that those are still being widely used.  Much to my relief, nobody
reported continuing to use the punch card utilities in production.

The final step will be to merge src/games into src/usr.bin.

This change will not be MFCed.

a capcity is given, no partitions are required. When no partitions are
given, no scheme needs to be specified either. This makes it possible

table, specify the scheme.
