Ah, sorry. do_wp_page() without page copy (reuse case) doesn't need sync.
Abou
Do you really need a "sync_icache_dcache()" in "do_wp_page()"?
I guess it is only needed when the EXEC bit of the PTE gets turned on.

This patch is against 2.6.23-rc1.
Changes v3 -> v4:
- avoid implementing flush_(i)cache_pages().
- added sync_icache_dcache() call.
- change Documentation/cachetlb.txt
Current ia64 kernel flushes icache by lazy_mmu_prot_update() *after*
set_pte(). This is wrong.
