[PATCH] flush icache before set_pte take6. [1/4] migration fix

2007-07-30 Thread KAMEZAWA Hiroyuki
In migration, a new page should be cache flushed before set_pte()
in some archs which have virtually-tagged cache..

V5 -> V6:
   * no changes (added new patches to the patch set)
V4 -> V5:
   * changed flush_icache_page to flush_cache_page.
