[-tip PATCH v4 0/6] pmem api, generic ioremap_cache, and memremap

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.
