sf buf allocation, use wakeup() instead of wakeup_one() to notify sf
buffer waiters about free buffer.
sf_buf_alloc() calls msleep(PCATCH) when SFB_CATCH flag was given,
and for simultaneous wakeup and signal delivery, msleep() returns
EINTR/ERESTART despite the thread was selected for wakeup_one(). As
result, we loose a wakeup, and some other waiter will not be woken up.

When a foreground job exits on a signal, a message is printed to stdout
about this. The buffer was not flushed after this which could result in the
message being written to the wrong file if the next command was a builtin
and had stdout redirected.
Example:
sh -c 'kill -9 $$'; : > foo; echo FOO:; cat foo

DP8381[56] and SiS 900/7016 controllers. After r212119, sis(4) no
longer reinitializes controller if ALLMULTI/PROMISC was changed.
However, RX filter handling code assumed some bits of the RX filter
is programmed by driver initialization. This caused ALLMULTI/PROMISC
configuration is ignored under certain conditions.
Fix that issue by reprogramming all bits of RX filter register.
While I'm here follow recommended RX filter programming steps
recommended by National DP8381[56] data sheet(RX filter should be

TSB is located within the 32-bit address space, which held true as long as
we were using virtual addresses magic-mapped before the location of the
kernel for addressing it. However, with r216803 in place when possible we
address it via its physical address instead, which on machines like Sun Fire
V880 have no physical memory in the 32-bit address space at all requires
to use 64-bit addressing. When using physical addressing it still should
be safe to assume that we can just ignore the lowest 10 bits of the address
as a minor optimization as we did before r216803.
This fixes hostap mode for at least ral(4) and run(4), because there is

multi-fragmented RX buffers such that driver have to allocate
physically contiguous buffers.
o Retire RL_FLAG_NOJUMBO flag and introduce RL_FLAG_JUMBOV2 to
mark controllers that use new jumbo frame scheme.
o Configure PCIe max read request size to 4096 for standard frames
and reduce it to 512 for jumbo frames.
o TSO/checksum offloading is not supported for jumbo frames on
these controllers. Reflect it to ioctl handler and driver
initialization.
o Remove unused rl_stats_no_timeout in softc.
o Embed a pointer to structure rl_hwrev into softc to keep track
of controller MTU limitation and remove rl_hwrev in softc since
that information is available through a pointer to structure
rl_hwrev.

assertion that is no longer required. Long ago, calls to vm_page_alloc()
from an interrupt handler had to specify VM_ALLOC_INTERRUPT so that
vm_page_alloc() would not attempt to reclaim a PQ_CACHE page from another vm
object. Today, with the synchronization on a vm object's collection of
PQ_CACHE pages, this is no longer an issue. In fact, VM_ALLOC_INTERRUPT now
reclaims PQ_CACHE pages just like VM_ALLOC_{NORMAL,SYSTEM}.

This is useful so that it is easier to exit on a signal than to reset the
trap to default and resend the signal. It matches ksh93. POSIX says that
'exit' without args from a trap action uses the exit status from the last
command before the trap, which is different from 'exit $?' and matches this
if the previous command is assumed to have exited on the signal.
If the signal is SIGSTOP, SIGTSTP, SIGTTIN or SIGTTOU, or if the default
action for the signal is to ignore it, a normal _exit(2) is done with exit
status 128+signal_number.
