f52ebb9e17 Use __ARM_ARCH to decide when ARM_TP_ADDRESS needs to be set. This fixes
an issue with clang 3.8.0 where none of the __ARM_ARCH_*__ macros were
defined on some ARMv6 kernel configs.

5c5d8c09ac Busy the mount point which is the owner of the audit vnode, around
audit_record_write().  This is important so that VFS_STATFS() is not
done on the NULL or freed mp and the check for free space is
consistent with the vnode used for write.

Add vn_start_write() braces around VOP_FSYNC() calls on the audit vnode.

Move repeated code to fsync vnode and panic to the helper
audit_worker_sync_vp().

2c013a8511 A fix to r292469: Iterate over the physical segments in descending rather
than ascending order in vm_phys_alloc_contig() so that, for example, a
sequence of contigmalloc(low=0, high=4GB) calls doesn't exhaust the supply
of low physical memory resulting in a later contigmalloc(low=0, high=1MB)
failure.

533cb3d787 FAST_DEPEND: Fix incremental builds leading to kernel panics.
This fixes .depend.genassym.o not being included.  genassym.o depends on
all of the system headers and when rebuilt regenerates assym.s which
lists offsets for critial .S files to utilize.  By having a struct in a
system header change its offsets and not have generassym.o be rebuilt,
this would lead to panics.

The flaw in the initial commit was seeing ${OBJS} in ${SYSTEM_OBJS} and
assuming it had all of ${SRCS} in it.  This is not the case though.  The
older mkdep code splits out all of the various SRC lists for generating
the .depend file.  It also includes ${GEN_CFILES}, which had genassym.c
and was the only significant file lacking from ${SYSTEM_OBJS} upon inspection,
since it is not linked in.  Rather than duplicate the likely
soon-to-be-removed mkdep lists, just add genassym.o to the DEPENDOBJS
list.  Using ${SRCS} as bsd.dep.mk does would be nice but there are many
files in the build that are only added to ${OBJS} and not ${SRCS}, such
as bf_enc.o derived from bf_enc.S for i386.

6ae16528e7 Add EFI ZFS boot support
This builds on the modular EFI loader support added r294060 adding a
module to provide ZFS boot support on EFI systems.

It should be noted that EFI uses a fixed size memory block for all
allocations performed by the loader so it may be necessary to tune this
size.

For example when building an image which uses mfs_root e.g. mfsbsd, adding
the following to /etc/make.conf would be needed to prevent EFI from running
out of memory when loading the mfs_root image.
EFI_STAGING_SIZE=128

transfer when the actual size is less than that, but there is no need to
extend or zero-out the data buffer, because the blklen register contains
the real transfer size and only that many bytes will be transferred.

activate a hotspare. The current code contains a race condition: vdev_geom
will sent the sysevent _before_ spa.c would update the vdev's status,
causing userland processes to see pool state that does not reflect the
device removal. This change moves the sysevent to spa.c, closing the race.
