The patch titled
b43: use the bitrev helpers rather than rolling a private one (update)
has been removed from the -mm tree. Its filename was
b43-use-the-bitrev-helpers-rather-than-rolling-a-private-one-update.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: b43: use the bitrev helpers rather than rolling a private one (update)
From: Harvey Harrison <harvey.harrison@xxxxxxxxx>
The 4-bit reversal flip_4bit is replaced with the bitrev helper
bitrev8 and a 4-bit shift. The B43_WARN is moved to the location
where a register is read from for checking there. The other caller
explicitly passes an array index which is guaranteed to be within range
and so a B43_WARN is not added there.
