[ARM] Feroceon: Feroceon-specific WA-cache compatible {copy,clear}_user_page()
This patch implements a set of Feroceon-specific {copy,clear}_user_page() routines that perform more optimally than the generic implementations. This also deals with write-allocate caches (Feroceon can run L1 D in WA mode) which otherwise prevents Linux from booting. [nico: optimized the code even further] Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Tested-by: Sylver Bruneau <sylver.bruneau@googlemail.com> Tested-by: Martin Michlmayr <tbm@cyrius.com> Signed-off-by: Nicolas Pitre <nico@marvell.com>
