Few new things available from now on:
- Data deduplication.
- Triple parity RAIDZ (RAIDZ3).
- zfs diff.
- zpool split.
- Snapshot holds.
- zpool import -F. Allows to rewind corrupted pool to earlier
transaction group.
- Possibility to import pool in read-only mode.

It used to choke on the notation "inb (%dx),%al" for "inb %dx,%al"; GNU
as accepts both forms. Which notation is more 'correct' is an open
question. :)
There are several bugfixes in this update, but the most important one is
to ensure __start_ and __stop_ symbols for linker sets and kernel module
metadata are always emitted in object files:
http://llvm.org/bugs/show_bug.cgi?id=9292
Before this fix, if you compiled kernel modules with clang, they would
not be properly processed by kldxref, and if they had any dependencies,
the kernel would fail to load those. Another problem occurred when
attempting to mount a tmpfs filesystem, which would result in 'operation
not supported by device'.
1) Add four new points that allow you to get more information
to cc algo's
2) Fix the case where user changes module on a existing TCB, in
such a case, the initialization module needs to be called on all nets.
3) Move htcp_cc structure to a union that other modules can use.
4) Add 5th point for get/set socket options for cc_module specific options

1) do not take a lock around the single atomic operation.
2) do not lose the invariant of lock by dropping/acquiring
ktrace_mtx around free() or malloc().

mps.c: Hide the 'out of chain frames' warning behind MPS_INFO.
mps_sas.c: Hide the SIM queue freeze/unfreeze messages behind MPS_INFO.
mpsvar.h: Bump the number of chain frames from 1024 to 2048. From
testing, it looks like this makes it less likely that we'll
run out of chain frames, and it doesn't cost much memory
(32K).

as the divisor to calculate the remaining rebuild time.

Now when one does 'make kernel ; make kernel' the second invocation
only does: `kernel.ko' is up to date.
rather than reproduce all the binary microcode files and relink the kernel.
