This reposts the patchkit to remove unchecked_isa_dma which was already
discussed some time ago. Instead it replaces it with interfaces
that declare the mask. Right now those interfaces map back to GFP_DMA
eventually, but it is a preparation for using the DMA mask allocator
eventually.
The previous time there were some disagreement on where to handle
the sense buffer bouncing which was done in low level drivers
in Boaz' version of the patchkit. I went back to the original
code which keeps sense buffer bouncing in the mid layer, which
should be non controversal.
I also removed blk_kmalloc and went back to the blk_q_mask() interfaces.
I believe there were no other controversies, so this should be ready
for merging now.
Other main changes was to forward port it to 2.6.27rc8 and doing some
retesting.
The changes are also available for pulling from
