From 59d1ff3bfb56d9b8cf3ec864857e6a4dfd9d2dba Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 9 Nov 2005 15:04:22 +0000 Subject: [ARM] Clean up save_and_disable_irqs macro and allow use of ARMv6 CPSID save_and_disable_irqs does not need to use mov + msr (which was introduced to work around a documentation bug which was propagated into binutils.) Use msr with an immediate constant, and if we're building for ARMv6 or later, use the new CPSID instruction.
