we want to use it.
The rate table was being initialised in low->high, but the link quality
table was being initialised high->low. So, when we did a lookup, we
would get the indexes wrong.
This started by a patch from dragonflybsd which reversed how the ni->in_ridx[]
array is being used; I'd rather it all be consistent. So, this is consistent.

Previously the polarity was for TTL levels, which are the reverse of RS-232.
Also add handling of the UART_PPS_INVERT_PULSE option bit in the sysctl
value, the same as was recently added to uart(4), so that people using TTL
level connections can request a logical inverting of the signal.
Use the named constants from the new dev/uart/uart_ppstypes.h for the pps
capture modes and option bits.
not call VOP_CLOSE() manually. Instead, delegate the close to
fo_close() performed as part of the fdrop() on the file failed to
open. For this, finish constructing file on error, in particular, set
f_vnode and f_ops.
Forcibly resetting f_ops to badfileops disabled additional cleanups
performed by fo_close() for some file types, in this case it was noted
that cdevpriv data was corrupted. Since fo_close() call must be
enabled for some file types, it makes more sense to enable it for all
files opened through vn_open_cred().

done on the NULL or freed mp and the check for free space is

Add vn_start_write() braces around VOP_FSYNC() calls on the audit vnode.
Move repeated code to fsync vnode and panic to the helper

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.

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.

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.

Some classes of IOAT hardware prefetch reads. DMA operations that
depend on the result of prior DMA operations must use the DMA_FENCE flag
to prevent stale reads.
(E.g., I've hit this personally on Broadwell-EP. The Broadwell-DE has a
different IOAT unit that is documented to not pipeline DMA operations.)

The boot code fsread was caching the result of meta data request and
reusing it even for calls with inode = 0, which is used to partitions

The result was that success was incorrectly returned for all partition
