Subject: [PATCH v2 00/25] replace ioremap_{cache|wt} with memremap
Date: Fri, 24 Jul 2015 22:37:54 -0400 [thread overview]
Message-ID: <20150725023649.8664.59145.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
Changes since v1 [1]:
1/ Drop the attempt at unifying ioremap() prototypes, just focus on
converting ioremap_cache and ioremap_wt over to memremap (Christoph)
2/ Drop the unrelated cleanups to use %pa in __ioremap_caller (Thomas)
3/ Add support for memremap() attempts on "System RAM" to simply return
the kernel virtual address for that range. ARM depends on this
functionality in ioremap_cache() and ACPI was open coding a similar
solution. (Mark)
4/ Split the conversions of ioremap_{cache|wt} into separate patches per
driver / arch.
5/ Fix bisection breakage and other reports from 0day-kbuild
---
While developing the pmem driver we noticed that the __iomem annotation
on the return value from ioremap_cache() was being mishandled by several
callers. We also observed that all of the call sites expected to be
able to treat the return value from ioremap_cache() as normal
(non-__iomem) pointer to memory.
This patchset takes the opportunity to clean up the above confusion as
well as a few issues with the ioremap_{cache|wt} interface, including:
1/ Eliminating the possibility of function prototypes differing between
architectures by defining a central memremap() prototype that takes
flags to determine the mapping type.
2/ Returning NULL rather than falling back silently to a different
mapping-type. This allows drivers to be stricter about the
mapping-type fallbacks that are permissible.

Subject: [PATCH v2 00/25] replace ioremap_{cache|wt} with memremap
Date: Sat, 25 Jul 2015 02:37:54 +0000 [thread overview]
Message-ID: <20150725023649.8664.59145.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
Changes since v1 [1]:
1/ Drop the attempt at unifying ioremap() prototypes, just focus on
converting ioremap_cache and ioremap_wt over to memremap (Christoph)
2/ Drop the unrelated cleanups to use %pa in __ioremap_caller (Thomas)
3/ Add support for memremap() attempts on "System RAM" to simply return
the kernel virtual address for that range. ARM depends on this
functionality in ioremap_cache() and ACPI was open coding a similar
solution. (Mark)
4/ Split the conversions of ioremap_{cache|wt} into separate patches per
driver / arch.
5/ Fix bisection breakage and other reports from 0day-kbuild
---
While developing the pmem driver we noticed that the __iomem annotation
on the return value from ioremap_cache() was being mishandled by several
callers. We also observed that all of the call sites expected to be
able to treat the return value from ioremap_cache() as normal
(non-__iomem) pointer to memory.
This patchset takes the opportunity to clean up the above confusion as
well as a few issues with the ioremap_{cache|wt} interface, including:
1/ Eliminating the possibility of function prototypes differing between
architectures by defining a central memremap() prototype that takes
flags to determine the mapping type.
2/ Returning NULL rather than falling back silently to a different
mapping-type. This allows drivers to be stricter about the
mapping-type fallbacks that are permissible.
