[ARM] 4453/1: Fully Decode ARM instruction set state in show_regs() tombstone
The ARM show_regs() tombstone only partially decodes which ARM ISA was executing at the time a fault occurred displaying either "(T)" for the Thumb case or nothing at all for other cases. This patch therefore explicitly identifies which state the processor is in at the time of a fault: ARM, Thumb, Jazelle or JazelleEE. Signed-off-by: George G. Davis <gdavis@mvista.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
