CVE: NA
---------------------------

Thread bits may be accessed from low-level code, so isolating is a measure
to avoid circular dependencies in header files.

The exact reason for circular dependency is WARN_ON() macro added in patch
edd63a27 "set_restore_sigmask() is never called without SIGPENDING (and
never should be)"
