Subject[BK PATCH] dma_declare_coherent_memory
From
Date
This patch has been refined in mm for quite a while and now seems stable
enough for mainline.

The patch is available at:

bk://linux-voyager.bkbits.net/dma-declare-coherent-memory-2.6

The short changelog is:

Andrew Morton:
o Fix sparc compile error in dma-mapping.h

James Bottomley:
o lib/bitmap.c: fix incorrect use of BITS_TO_LONGS()
o dma_alloc_coherent() still needs to support a NULL device
o Fix region sizing problem in dma_mark_declared_memory_occupied()
o Fix bug in __get_vm_area() alignment code
o Fix incorrect prototype in the dma_declare_coherent_memory API
o Convert NCR_Q720 to use dma_declare_coherent_memory
o Add x86 implementation of dma_declare_coherent_memory
o Add vmalloc alignment constraints
o Add memory region bitmap implementations
o Add dma_declare_coherent_memory() API

Petr Vandrovec:
o nsc-ircc driver crashes on shutdown
