300952 by ed:
Invoke the dirname() function in a POSIX compliant way.

POSIX requires that the argument of dirname() is of type "char *". In
other words, the input buffer can be modified by the function to store
the directory name.

Pull a copy of the string before calling dirname(). We don't care about
freeing up the memory afterwards, as this is done at the very bottom of
main(), right before the program terminates.

ARM GIC: Allow to setup interrupt without configuration data.
In some cases, like for PCI devices, only interrupt numbers are enumerated
from HW. In this case, use INTR_foo_CONFORM as level and trigger values.

Now that PIE is free of runtime floating point,  revert r300853 to
reconnect PIE to the build.

300949 by truckman:
Cast some expressions that multiply a long long constant by a
floating point constant to int64_t.  This avoids the runtime
conversion of the the other operand in a set of comparisons from
int64_t to floating point and doing the comparisions in floating
point.

This allows the CXX hack in r300917 for external GCC to work for
the lib32 build.  It is also the same pattern as the native
build uses by adding the tools into CROSSENV for external
toolchain, rather than make overrides.

External GCC: Ensure our libstdc++ symlink to libc++ is found.

Similar to r300917, the search path for our symlink hack must come

GCC XCC -isystem hack: Ensure CXX search =/usr/include/c++1/v1 first.

The C++ header files must be searched before /usr/include.

The original code in Makefile.inc1 did this before the change in r297271 to
use -isystem.  The libc++ import in r300770 fixed the bug introduced in
r297271 by swapping XCFLAGS and XCXXFLAGS ordering in CROSSENV.

Moving the code from Makefile.inc1 to bsd.sys.mk in r300886 also made it
more difficult to control the order of the flags.  CXXFLAGS is based on
CFLAGS, so any additions to it will come after CFLAGS.  The CROSSENV
code from Makefile.inc1 was such that it was ensured the CXXFLAGS came
first by setting them directly in CXX.  Using CXXFLAGS+=-I would work
here, but instead continue to use -isystem by adding it to CXX so it
comes before CFLAGS.

zfsd(8), the ZFS fault management daemon

Add zfsd, which deals with hard drive faults in ZFS pools. It manages
hotspares and replements in drive slots that publish physical paths.

lib/Makefile
share/mk/bsd.libnames.mk

	Add a directory for libdevdctl's include files

etc/mtree/BSD.tests.dist

etc/mtree/BSD.var.dist
	Add /var/db/zfsd/cases, where zfsd stores case files while it's shut
	down.

etc/rc.d/Makefile
etc/rc.d/zfsd
	Add zfsd's rc script

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c
	Fix the resource.fs.zfs.statechange message. It had a number of
	problems:

	It was only being emitted on a transition to the HEALTHY state.
	That made it impossible for zfsd to take actions based on drives
	getting sicker.

	It compared the new state to vdev_prevstate, which is the state that
	the vdev had the last time it was opened.  That doesn't make sense,
	because a vdev can change state multiple times without being
	reopened.

	vdev_set_state contains logic that will change the device's new
	state based on various conditions.  However, the statechange event
	was being posted _before_ that logic took effect.  Now it's being
	posted after.

Implement SHA-512 truncated (224 and 256 bits)

This implements SHA-512/256, which generates a 256 bit hash by
calculating the SHA-512 then truncating the result. A different initial
value is used, making the result different from the first 256 bits of
the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on
64bit platforms, so the result is a faster 256 bit hash.

The main goal of this implementation is to enable support for this
faster hashing algorithm in ZFS. The feature was introduced into ZFS
in r289422, but is disconnected because SHA-512/256 support was missing.
A further commit will enable it in ZFS.

This is the follow on to r292782

Don't panic in hwpmc when stopping sampling.

When hwpmc stops sampling it will set the pm_state to something other
than PMC_STATE_RUNNING. This means the following sequence can happen:

CPU 0: Enter the interrupt handler
CPU 0: Set the thread TDP_CALLCHAIN pflag
CPU 1: Stop sampling
CPU 0: Call pmc_process_samples, sampling is stopped so clears ps_nsamples
CPU 0: Finishes interrupt processing with the TDP_CALLCHAIN flag set
CPU 0: Call pmc_capture_user_callchain to capture the user call chain
CPU 0: Find all the pmc sample are free so no call chains need to be captured
CPU 0: KASSERT because of this

This fixes the issue by checking if any of the samples have been stopped
and including this in te KASSERT.
