Subject: [-tip PATCH v4 0/6] pmem api, generic ioremap_cache, and memremap
Date: Thu, 11 Jun 2015 17:19:12 -0400 [thread overview]
Message-ID: <20150611211354.10271.57950.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
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.

Dan Williams (5):
arch: unify ioremap prototypes and macro aliases
cleanup IORESOURCE_CACHEABLE vs ioremap()
arch/*/asm/io.h: add ioremap_cache() to all architectures
devm: fix ioremap_cache() usage
arch: introduce memremap_cache() and memremap_wt()
