9ca1fe0db8 CARP should be capable to run on if_bridge(4). Unfortunately,
this commit is not enough to enable CARP operation on
if_bridge(4), because the latter doesn't handle or even
initialize its ifp->if_link_state.

79257559ee BSP is not added to the mask of valid target CPUs for interrupts
in set_apic_interrupt_ids(). Besides, set_apic_interrupts_ids() is not
called in the !SMP case too.
Fix this by:
- Adding the BSP as an interrupt target directly in cpu_startup().
- Remove an obsolete optimization where the BSP are skipped in
  set_apic_interrupt_ids().

8a8be77610 Remove unused and wrong SA_PROC internal signal property.
The SA_PROC signal property indicated whether each signal number is directed
at a specific thread or at the process in general. However, that depends on
how the signal was generated and not on the signal number. SA_PROC was not
used.

5844994b1e sem_open: Make sure to fail an O_CREAT|O_EXCL open, even if that semaphore
is already open in this process.

If the named semaphore is already open, sem_open() only increments a
reference count and did not take the flags into account (which otherwise
happens by passing them to open()). Add an extra check for O_CREAT|O_EXCL.

e2e4a2c2a1 Break out the legacy duration and protection code into routines,
call these after rate control selection is done.

The duration/protection code wasn't working - it expected the rix to
be valid.  Unfortunately after I moved the rate control selection into
late in the process, the rix value isn't valid and thus the protection/
duration code would get things wrong.

HT frames are now correctly protected with an RTS and for the AR5416,
this involves having the aggregate frames be limited to 8K.

TODO:

* Fix up the DMA sync to occur just before the frame is queued to the
  hardware.  I'm adjusting the duration here but not doing the DMA
  flush.

* Doubly/triply ensure that the aggregate frames are being limited to
  the correct size, or the AR5416 will get unhappy when TXing RTS-protected
  aggregates.

045bc7882e Enforce the RTS aggregation limit if RTS/CTS protection is enabled;
if any subframes in an aggregate have different protection from the
first frame in the formed aggregate, don't add that frame to the
aggregate.

This is likely a suboptimal method (I think we'll mostly be OK marking
frames that have seqno's with the same protection as normal data frames)
but I'll just be cautious for now.
