gcc-plugins/stackleak: Ignore .noinstr.text and .entry.text
The .noinstr.text section functions may not have "current()" sanely available. Similarly true for .entry.text, though such a check is currently redundant. Add a check for both. In an x86_64 defconfig build, the following functions no longer receive stackleak instrumentation: __do_fast_syscall_32() do_int80_syscall_32() do_machine_check() do_syscall_64() exc_general_protection() fixup_bad_iret() Suggested-by: Peter Zijlstra <peterz@infradead.org> Cc: Alexander Popov <alex.popov@linux.com> Signed-off-by: Kees Cook <keescook@chromium.org>
