This patch fixes ppc64 __ioremap() so that it stops adding implicitely _PAGE_GUARDED when the cache is not writeback, and instead, let the callers provide the flag they want here. This allows things like framebuffers to explicitely request a non-cacheable and non-guarded mapping which is more efficient for that type of memory without side effects. The patch also fixes all current callers to add _PAGE_GUARDED except btext, which is fine without it.
