ARM: 7962/2: Make all mcpm functions notrace
The functions in mcpm_entry.c are mostly intended for use during scary cache and coherency disabling sequences, or do other things which confuse trace ... like powering a CPU down and not returning. Similarly for the backend code. For simplicity, this patch just makes whole files notrace. There should be more than enough traceable points on the paths to these functions, but we can be more fine-grained later if there is a need for it. Jon Medhurst: Also added spc.o to the list of files as it contains functions used by MCPM code which have comments comments like: "might be used in code paths where normal cacheable locks are not working" Signed-off-by: Dave Martin <dave.martin@linaro.org> Signed-off-by: Jon Medhurst <tixy@linaro.org> Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
