by timeout/error of one of probe commands, process may continue infinitely.
Make CAM ATA more robust to faulty devices and false positive detections,
abort probe after two restarts on timeouts or ten on other errors.
dialog(1) is run without arguments and works as expected. Therefore,
it should be part of the manual as well.
Note: dialog(1) has not been updated for many years and is not actively
maintained at the moment.

Because slave PICs send all interrupts to their CPU 0 output line (which
is routed to a pin on the master PIC), changes to per-CPU register banks
like EOI on the slave PIC must be accessed for CPU 0, instead of the
CPU actually processing the interrupt.

There are special cases where tty_rel_free() can be called twice in a
row, namely when closing and revoking the TTY at the same moment. Only
call destroy_dev_sched_cb() once.

the context of the process that reduced the effective count. Previously
all truncation as a result of unlink happened in the softdep flush
thread. This had the effect of being impossible to rate limit properly
with the journal code. Now the process issuing unlinks is suspended
when the journal files. This has a side-effect of improving rm
performance by allowing more concurrent work.
- Handle two cases in inactive, one for effnlink == 0 and another when
nlink finally reaches 0.
- Eliminate the SPACECOUNTED related code since the truncation is no
longer delayed.

directory truncation to proceed before the link has been cleared. This
is accomplished by detecting a directory with no . or .. links and
clearing the named directory entry in the parent.
- Add a new function ino_remref() which handles the details of removing
a reference to an inode as a result of a lost directory. There were
some minor errors in various subcases of this routine.

vmio buffer can be replaced by a call to vm_page_grab().

returns the requested unit number if it is free. If the number is
already allocated or out of the range, -1 is returned.
Update alloc_unr(9) manual page accordingly and add a MLINK for
alloc_unr_specific(9).

apart from generally doing the wrong thing can lead to a panic when a
CPU is told to IPI itself (which sun4u doesn't support).

since we no longer need to mark the pages with VPO_CLEANCHK to denote
the progress. It is enough to remember the current position by index
before dropping the object lock.
Remove VPO_CLEANCHK and VM_PAGER_IGNORE_CLEANCHK as unused.
