[PATCH] pass "page" pointer to clear_user_page()/copy_user_page()

Hi Linus,

Are you willing to change the interfaces of clear_user_page() and
copy_user_page() so that they can receive the relevant page pointer as
a separate argument?  I need this on ia64 to implement the lazy-cache
flushing scheme.

I believe PPC would also benefit from this.
