Subject: [PATCH v2 0/3] Switch to ioremap_wc in the SRAM allocator code

Fix alignment faults seen during play-back of files with specific
sampling rates such as 44.1K. This is based on the discussion here:
http://www.spinics.net/lists/arm-kernel/msg384647.html

Patch 1 is needed as m32r arch does not define ioremap_wc. Patch 2 adds a
resource managed helper function for ioremap_wc which is used in patch 3.

Changes since v1:
	- Fix the compilation error with m32r due to missing ioremap_wc
	definition.
	- Fixed minor indentation issues.

Note: Other architectures either have ioremap_wc defined or are including
generic "io.h"/"iomap.h". c6x arch is the only one I am not sure of.

Abhilash Kesavan (3):
  m32r: add definition of ioremap_wc to io.h
  lib: devres: add a helper function for ioremap_wc
  misc: sram: switch to ioremap_wc from ioremap
