The pmem api is responsible for shepherding data out to persistent
media. The pmem driver uses this api, when available, to assert that
data is durable by the time bio_endio() is invoked. When an
architecture or cpu can not make persistence guarantees the driver warns
and falls back to "best effort" implementation.
Changes since v3 [1]:
Rebased on tip/master now that Toshi's ioremap_wt() patches have landed
in -tip. The primary change was reflowing the patches against the newly
alphabetized 'select' options under config X86.
