From 4e3c1944808b0278ea4733afcde5cb9421f8a570 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Sun, 2 Dec 2012 17:44:36 +0000 Subject: [PATCH] ARM: virt: use PSR_N_BIT for detecting boot CPU mode mismatch During boot, we detect whether or not all CPUs are brought up in the same mode and signal this to the kernel using the N bit in the SPSR. This patch tidies up the checking code to use the PSR_N_BIT macro, rather than hardcoding the bit field and commenting it as such.
