times mount is called.
Limit the automatic behavior to when AUTO is specified (as it is in
etc/defaults/rc.conf) and for everything else take advantage of all
of the goodness in checkyesno.
Writing the TX power registers is the same between all of these chips
and later NICs (AR9287, AR9271 USB, etc.) so this will reduce code
duplication when those NICs are added to the HAL.
goes to zero. E.g., the vnode might be only shared-locked at the time of
vput() call. Such vnodes are kept in the hash, so they can be found later.
If ffs_valloc() allocated an inode that has its vnode cached in hash, and
still owing the inactivation, then vget() call from ffs_valloc() clears
VI_OWEINACT, and then the vnode is reused for the newly allocated inode.
The problem is, the vnode is not reclaimed before it is put to the new
use. ffs_valloc() recycles vnode vm object, but this is not enough.
In particular, at least v_vflag should be cleared, and several bits of
UFS state need to be removed.
It is very inconvenient to call vgone() at this point. Instead, move
some parts of ufs_reclaim() into helper function ufs_prepare_reclaim(),
and call the helper from VOP_RECLAIM and ffs_valloc().

stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).
ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool

referred to as the experimental server. It also adds a new command
line option "-o" to both mountd and nfsd that forces them to use the
old/regular NFS server. The "-e" option for these commands is now
a no-op, since the new server is the default. I will be committing rc
script and man changes soon. Discussed on freebsd-fs@.
If EV_EXIT causes an exit, use the exception mechanism to unwind
redirections and local variables. This way, if the final command is a
redirected command, an EXIT trap now executes without the redirections.
Because of these changes, EV_EXIT can now be inherited by the body of a
function, so do so. This means that a function no longer prevents a fork
before an exec being skipped, such as in
f() { head -1 /etc/passwd; }; echo $(f)
Wrapping a single builtin in a function may still cause an otherwise
unnecessary fork with command substitution, however.
An exit command or -e failure still invokes the EXIT trap with the
original redirections and local variables in place.
Note: this depends on SHELLPROC being gone. A SHELLPROC depended on
keeping the redirections and local variables and only cleaning up the
state to restore them.
Hold the vnode around the region where object lock is dropped, until
vnode lock is acquired.
Do not drop the vnode reference for a case when the object was
deallocated during unlock. Note that in this case, VV_TEXT is cleared
by vnode_pager_dealloc().

called vfs_busyfs(), which calls vfs_busy() with MBF_MNTLSTLOCK.

spurious (and fatal) interrupt errors.
One user reported seeing this:
Apr 22 18:04:24 ceres kernel: ar5416GetPendingInterrupts: fatal error,
ISR_RAC 0x0 SYNC_CAUSE 0x2000
SYNC_CAUSE of 0x2000 is AR_INTR_SYNC_LOCAL_TIMEOUT which is a bus timeout;
this shouldn't cause HAL_INT_FATAL to be set.
After checking out ath9k, ath9k_ar9002_hw_get_isr() clears (*masked)
before continuing, regardless of whether any bits in the ISR registers
are set. So if AR_INTR_SYNC_CAUSE is set to something that isn't
treated as fatal, and AR_ISR isn't read or is read and is 0, then
(*masked) wouldn't be cleared. Thus any of the existing bits set
that were passed in would be preserved in the output.
The caller in if_ath - ath_intr() - wasn't setting the masked value
to 0 before calling ath_hal_getisr(), so anything that was present
in that uninitialised variable would be preserved in the case above
of AR_ISR=0, AR_INTR_SYNC_CAUSE != 0; and if the HAL_INT_FATAL bit
was set, a fatal condition would be interpreted and the chip was
reset.
This patch does the following:
* ath_intr() - set masked to 0 before calling ath_hal_getisr();
* ar5416GetPendingInterrupts() - clear (*masked) before processing
continues; so if the interrupt source is AR_INTR_SYNC_CAUSE
and it isn't fatal, the hardware isn't reset via returning
HAL_INT_FATAL.
This doesn't fix any underlying errors which trigger
AR_INTR_SYNC_LOCAL_TIMEOUT - which is a bus timeout of some
sort - so that likely should be further investigated.

- 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.

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.
