The definition of __exception_irq_entry for CONFIG_FUNCTION_GRAPH_TRACER=y needs linux/ftrace.h, but this creates a circular dependency with it's current home in asm/system.h. Create asm/exception.h and update all current users. v4: - rebase to rmk/for-next v3: - remove redundant includes of linux/ftrace.h v2: - document the usage restricitions of __exception* Cc: Zoltan Devai <zdevai@gmail.com> Signed-off-by: Jamie Iles <jamie@jamieiles.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
