[PATCH kernel RFC 0/2] powerpc/ioda2: An attempt to allow DMA masks between 32 and 59

[Alexey Kardashevskiy]

This is an attempt to allow DMA mask 40 or similar which are not large
enough to use either a PHB3 bypass mode or a sketchy bypass.

This is based on sha1
582549e3fbe1 Linus Torvalds Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma 

Please comment. Thanks.
