Message-ID: <20101026025432.23512.89593.stgit@warthog.procyon.org.uk>

Subject: [PATCH 17/43] MN10300: Reorder asm/cacheflush.h to put primitives
first
Reorder asm/cacheflush.h to put arch primitives first, before the main
functions so that the main functions can be inline asm rather than #defines
when non-trivial.
