From 4fb2847437d871fe579f820ceb18031db3359901 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Fri, 25 Sep 2009 13:39:47 +0100 Subject: ARM: 5727/1: Pass IFSR register to do_PrefetchAbort() Instruction fault status register, IFSR, was introduced on ARMv6 to provide status information about the last insturction fault. It needed for proper prefetch abort handling. Now we have three prefetch abort model: * legacy - for CPUs before ARMv6. They doesn't provide neither IFSR nor IFAR. We simulate IFSR with section translation fault status for them to generalize code; * ARMv6 - provides IFSR, but not IFAR; * ARMv7 - provides both IFSR and IFAR. Signed-off-by: Kirill A.
