Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
Since arm64 does not use -pg in CC_FLAGS_FTRACE with DYNAMIC_FTRACE_WITH_REGS, skip running recordmcount by exporting CC_USING_PATCHABLE_FUNCTION_ENTRY. Signed-off-by: Sami Tolvanen <samitolvanen@google.com> --- arch/arm64/Makefile | 1 + 1 file changed, 1 insertion(+)
