[PATCH] bitmap: region multiword spanning support
Add support to the lib/bitmap.c bitmap_*_region() routines
For bitmap regions larger than one word (nbits > BITS_PER_LONG). This removes
a BUG_ON() in lib bitmap.
I have an updated store queue API for SH that is currently using this with
relative success, and at first glance, it seems like this could be useful for
x86 (arch/i386/kernel/pci-dma.c) as well. Particularly for anything using
dma_declare_coherent_memory() on large areas and that attempts to allocate
large buffers from that space.
Paul Jackson also did some cleanup to this patch.
