commitd1e420772cupstream. The signal delivery logic was modified to always set the PKRU bit in xregs_state->header->xfeatures by this commit:ae6012d72f("x86/pkeys: Ensure updated PKRU value is XRSTOR'd") However, the change derives the bitmask value using XGETBV(1), rather than simply updating the buffer that already holds the value. Thus, this approach induces an unnecessary dependency on XGETBV1 for PKRU handling. Eliminate the dependency by using the established helper function. Subsequently, remove the now-unused 'mask' argument. Signed-off-by: Chang S.
