Subject: [PATCH v2 1/5] ARM: use generic version of identical asm headers

From: [email-masked] (Rob Herring)
Date: Sat, 4 Aug 2012 20:23:56 -0500

From: Rob Herring <[email-masked]>

Inspired by the AArgh64 claim that it should be separate from ARM and one
reason was being able to use more asm-generic headers. Doing a diff of
arch/arm/include/asm and include/asm-generic there are numerous asm
headers which are functionally identical to their asm-generic counterparts.
Delete the ARM version and use the generic ones.
