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
