[PATCH 03/12] block: bio_release_pages: use flags arg instead of bool
From: John Hubbard <jhubbard at nvidia.com> In commit d241a95f3514 ("block: optionally mark pages dirty in bio_release_pages"), new "bool mark_dirty" argument was added to bio_release_pages. In upcoming work, another bool argument (to indicate that the pages came from get_user_pages) is going to be added. That's one bool too many, because it's not desirable have

[PATCH 4/4] vbios/prom: fetch the vbios using only aligned 32-bit accesses
Other kind of accesses are unreliable on Maxwell cards. As advised by NVIDIA, let's only use 32-bit accesses to fetch the vbios from PROM. This fixes vbios fetching on my nve7 which failed in certain specific conditions. I suggest we Cc stable, for all kernels they still maintain after the big rewrite.
