[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]
