From da0916539d20f257dfa46784357300e49d6bfd00 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 6 Sep 2008 17:19:08 +0100 Subject: [ARM] Convert set_pte_ext implementions to macros There are actually only four separate implementations of set_pte_ext. Use assembler macros to insert code for these into the proc-*.S files.
