Subject: sh: Provide optimized unaligned loads on SH-4A.
X-Git-Tag: v2.6.29-rc1~591^2~96
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=95b781c239f53b4c7ecaf2989404ec6379b2409b;p=pandora-kernel.git

sh: Provide optimized unaligned loads on SH-4A.

This adds support for unaligned loads on SH-4A, using the SH-4A's
neutered movua.l instruction. As movua.l is r0-inspired, stores are
still handled through the packed struct.

Based on asm-generic/unaligned.h by Harvey Harrison.
