corresponding flag(s) in the new map entry. Previously, the caller was
responsible for setting them after vm_map_insert() returned.
Pass MAP_STACK_GROWS_DOWN to vm_map_insert() from vm_map_growstack() when
extending the stack in the downward direction.
Together these changes slightly simplify the caller's task when creating a
downward growing stack. In particular, the caller no longer needs to clip
the previous entry, because the new stack entry can't possibly coalesce
with the previous entry.

From one side it allows to remove CTL_FLAG_TASK_PENDING flag, handling of
which significantly complicates fine-grained locking. From the other side
it reduces task management requests latency even below then that flag could.
As downside, it denies task management code to sleep, but that is not needed
any way now.

This should allow to abort commands doing mostly disk I/O, such as VERIFY
or WRITE SAME. Before this change CTL_FLAG_ABORT was only checked around
data moves, which for these commands may not happen for a very long time.

SPC-4 recommends T10 vendor ID based LUN ID was created by concatenating
product name and serial number (and istgt follows that). But product name
is 16 bytes long by itself, so 16 bytes total length is clearly not enough
to fit both.
To keep compatibility with existing configurations, pad short device IDs
to old length of 16, same as before.
This change probably breaks CTL user-level ABI, so control tools should
be rebuilt after this change.

we're now back to the pre-r228483 level of default verbosity. This in
turn again typically allows for reading information that userland might
have printed on the screen before initiating a halt, but still permits
to debug potential device shutdown problems on system shutdown via
CAM_DEBUG etc.

Posix strptime() requires support for %t and %n, which were added
to the illumos port. Curiously we were skipping white spaces by
default in most other cases making %t meaningless.
We now skip spaces in the case of the %e specifier as strftime(3)
explicitly adds a space for the single digit case.

This change is based upon the code from the submitter, and made
following changes:
- Exclude addresses assigned on interfaces which are down, like NetBSD
does.
- Exclude addresses assigned on interfaces which are ifdisabled.

stored on failing disk drives), terminating a busy session

- Don't compare the DMA map to NULL to determine if bus_dmamap_unload()
should be called when releasing a static allocation. Instead, compare
the bus address against 0.
- Don't assume that the DMA map for static allocations is NULL. Instead,
save the value set by bus_dmamem_alloc() so it can later be passed to
bus_dmamem_free(). Also, add missing calls to bus_dmamap_unload() in
these cases before freeing the buffer.
- Use the bus address from the bus_dma callback instead of calling
vtophys() on the address allocated by bus_dmamem_alloc().
