- cosmetic changes and style fixes
- Trick GAS/GCC into compiling access to TICK/(S)TICK_COMPARE independently
of the selected instruction set. Moreover, sun4v doesn't need the WAR for
BlackBird CPUs.
- Rename the "xor" parameter to "xorval" as the former is a reserved keyword
in C++.
vfs_sanitizeopts() can handle "ro" and "rw" options properly, there is
no more need to add "noro" in vfs_donmount() to cancel "ro".
This also fixes a problem of canceling options beginning with "no".
For example, "noatime" didn't cancel "nonoatime". Thus it was possible
that both "noatime" and "nonoatime" were active at the same time.

- Enable flowid (TSS) support.
- Added "per-fastpath" locks and watchdog timeouts.
- Fixed problem where the CQ producer index was advanced beyond
the size of the CQ ring during initialization.
- Replaced hard-coded debug levels in some debug print statements.
- More style(9) fixes.

r220375 all drivers enabled in the sparc64 GENERIC should be either
correctly using bus_dmamap_sync(9) calls or supply BUS_DMA_COHERENT
when appropriate or as a workaround for missing bus_dmamap_sync(9)
calls (sound(4) drivers and partially sym(4)). In at least some
configurations taking advantage of the streaming cache results in
a modest performance improvement.
- Remove the memory barrier for BUS_DMASYNC_PREREAD which as the
comment already suggested is bogus.
- Add my copyright for having implemented several things like support
for the Fire and Oberon IOMMUs, taking over PROM IOMMU mappings etc.
should respond with all zeroes to any access to slave registers. Test with
PATA devices confirmed such behavior. Unluckily, Intel SATA controllers in
legacy emulation mode behave differently, not making any difference between
ATA and ATAPI devices. It causes false positive slave device detection and,
as result, command timeouts.
To workaround this problem, mask result of legacy-emulated soft-reset with
the device presence information received from the SATA-specific registers.
nm_maxfilesize. This value rarely, if ever, changes
and the nm_mtx mutex is locked/unlocked earlier in
the function, which should be sufficient to avoid
getting a stale cached value for it. There is a
discussion w.r.t. what these tests should be, but
I've left them basically the same as the regular
NFS client for now.

- Test newslog with clasic naming of rotates files to actually test
the correct number of log files as newsyslog now does the correct
thing post r220926.
- Add some more newsyslog tests which tests keeping 0, 1, and 2
logfiles.
requested in newsyslog.conf. This was only the case using the non-time
based filenames (.0, .1, .2 etc.).
The change also makes newsyslog clean clean up the old extra logfile so
users don't end up with a single stale logfile which won't be rotated
out.
This change also cleans up some code a bit to avoid more copy / paste
code and removes some old copy / paste code in the process.

allocate all of them at attach time. This allows to avoid moving
keys around in the most-recently-used queue and needs no mutex
synchronization nor refcounting.

create reasonably large cache for the keys that is filled when
needed. The previous version was problematic for very large providers
(hundreds of terabytes or serval petabytes). Every terabyte of data
needs around 256kB for keys. Make the default cache limit big enough
to fit all the keys needed for 4TB providers, which will eat at most
1MB of memory.

- Device with ID 0x29218086 is a 2-port variant of ICH9 in legacy mode.
Skip probing for nonexistent slave devices there.
It allows to avoid false positive device detection under Xen, that caused
long probe delays due to subsequent IDENTIFY command timeouts.

probes for debugging events which are just impossible to debug
with printf/log (eg packet TX/RX handling; AMPDU handling.)
The probes and operations themselves will appear in subsequent

This is only a problem if IFS contains digits, which is unusual but valid.
Because of an incorrect fix for PR bin/12137, "${#parameter}" was treated
as ${#parameter}. The underlying problem was that "${#parameter}"
erroneously added CTLESC bytes before determining the length. This
was properly fixed for PR bin/56147 but the incorrect fix was not backed
out.

secondary role. It is possible that the remote node is primary, but only
because there was a role change and it didn't finish cleaning up (unmounting
file systems, etc.). If we detect such situation, wait for the remote node
to switch the role to secondary before accepting I/Os. If we don't wait for
it in that case, we will most likely cause split-brain.
