Subject: [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]
