From 0ed1507183adea174bc4b6611b50d90e044730c2 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Thu, 24 Apr 2008 01:31:45 -0400 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.
