From 198a0a927ab9c52a68297120ee6dd4e36a975b0e Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 26 Jun 2011 13:51:44 +0100 Subject: [PATCH] ARM: entry: abort-macro: simplify do_ldrd_abort We can test bits 27:25 and 20 of the instruction at the same time; there's no need to separate out the check of bit 20.
