ARM: 8017/1: Move asm macro get_thread_info to asm/assembler.h
asm/assembler.h is a better place for this macro since it is used by asm files outside arch/arm/kernel/ Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Tested-by: Arun KS <getarunks@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
