remove duplicates. We cannot sort SUBDIR because many Makefiles
have .WAIT in the list which is strongly ordering. Rather than
try to second guess when to sort and when to not sort depending
on .WAIT being in the list, just remove duplicates.
While here update the list of devices id to match the one in linux 3.8.13

armv6. It's too ambiguous. We do use the softfp ABI for the moment on
armv6, but we allow floating point register use (and the compilers
will generate it). This is too ambiguous to use it as a decider for
which algorithms to use on the platform. Err on the side of caution
and not define it.

its_cmd_send() can be called by multiple CPUs simultaneously.
After the command is pushed to ITS command ring the completion
status is polled using global pointer to the next free ring slot.
Use copied pointer and provide correct locking to avoid spurious
pointer value when concurrent access occurs.

Convert filemon_lock and struct filemon* lock to sx(9), rather than a
self-rolled reader-writer lock, and hold it for the entire time needed.
At least filemon_lock_write() was not checking for active readers when
it would successfully return with the write lock "held". This led to
a race with reading entries from filemon_inuse as they were removed. This
could be seen with QUEUE_MACRO_DEBUG enabled, causing -1 to be read as an
entry rather than a valid struct filemon*.
Fixing filemon_lock_write() to check readers was insufficient to fix the
races.
sx(9) was used as the lock could be held while taking proctree_lock and sleeping
in fo_write.

The initial check for a matching ] was incorrect if a ] may be consumed by a
[:class:]. The subsequent loop assumed that there must be a ].
Remove the initial check and make the loop cope with a missing ].
