[PATCH] flush icache before set_pte() take 5. [1/2] cache flush in migration

In migration, a new page should be cache flushed before set_pte() in some archs which have virtually-tagged cache.. V4 -> V5: * changed flush_icache_page to flush_cache_page. Signed-Off-By: KAMEZAWA Hiruyoki <[EMAIL PROTECTED]> --- mm/migrate.c |1 + 1 file changed, 1 insertion(+) Index

[PATCH] flush icache before set_pte() take 5.

Appliled comments on take 4. patches are against 2.6.23-rc1. Changes: - changes flush_icache_page to be flush_cache_page() in remove_migration_pte(). - removed sync_icache_dcahe() in page reuse case of do_wp_page(). Considerations: - I can add CONFIG_MONTECITO if necessary. But it will be
