1b82e02f4d Add bit_count to the bitstring(3) api 
Add a bit_count function, which efficiently counts the number of bits set in
a bitstring.

sys/sys/bitstring.h
tests/sys/sys/bitstring_test.c
share/man/man3/bitstring.3
	Add bit_alloc

sys/kern/subr_unit.c
	Use bit_count instead of a naive counting loop in check_unrhdr, used
	when INVARIANTS are enabled. The userland test runs about 6x faster
	in a generic build, or 8.5x faster when built for Nehalem, which has
	the POPCNT instruction.

sys/sys/param.h
	Bump __FreeBSD_version due to the addition of bit_alloc

UPDATING
	Add a note about the ABI incompatibility of the bitstring(3)
	changes, as suggested by lidl.

2c96ac7a39 Use the new(-ish) CP15_SCTLR macro to generate system control reg accesses 
where possible.  In the places that doesn't work (multi-line inline asm,
and places where the old armv4 cpufuncs mechanism is used), annotate the
accesses with a comment that includes SCTLR.  Now a grep -i sctlr can find
all the system control register manipulations.

No functional changes.

3f54ec85e8 Fix ada(4) trim support quirk setting. 
I broke broke the quirk in the ada(4) driver disabling NCQ trim support
in revision 300207.  The support flags were set before the quirks were
loaded.

sys/cam/ata/ata_da.c:
	Call adasetflags() after loading quirks, so that we'll set the
	flags accurately.

10b4196bd0 Correct an error in a comment: One of the conditions for page allocation 
is actually the opposite of that stated in the comment.

Remove an unnecessary assignment.  Use an assertion to document the fact
that no assignment is needed.
