Subject: [PATCH v3 0/3] Ordered I/O accessors

Hi,

This version replaces the do { ... } while (0) constructs in the final
patch with ({ ... }) to avoid errors in drivers putting brackets around
the write*() accessors. To avoid the write*() macro having a non-void
type (and possibly the compiler generating code to read a register), the
first patch explicitly casts the __raw_write*() accessors to (void).


Catalin Marinas (3):
      ARM: Introduce *_relaxed() I/O accessors
      ARM: Convert L2x0 to use the IO relaxed operations
      ARM: Add barriers to the I/O accessors if ARM_DMA_MEM_BUFFERABLE
