And update linux/linkage.h, which requires in turn that we make these files switch from ENTRY()/ENDPROC() to SYM_FUNC_START()/SYM_FUNC_END(): tools/perf/arch/arm64/tests/regs_load.S tools/perf/arch/arm/tests/regs_load.S tools/perf/arch/powerpc/tests/regs_load.S tools/perf/arch/x86/tests/regs_load.S We also need to switch SYM_FUNC_START_LOCAL() to SYM_FUNC_START() for the functions used directly by 'perf bench', and update tools/perf/check_headers.sh to ignore those changes when checking if the kernel original files drifted from the copies we carry. This is to get the changes from:6dcc5627f6
