John,
Please pull this patch for the wireless-2.6 tree.
This patch depends on the 64bit DMA patch, which is already
submitted for inclusion.
Convert the bitfields in the bcm43xx DMA code to properly
aligned u8 booleans. These flags are accessed in the DMA
hotpath, so it's a good idea to waste a few bytes of memory
for the sake of speed by not requiring masking (and probably
shifting) of the bitfields.
