In order to remove internal.h make signal.h independent of it. Include asm/fpu/xstate.h to fix a missing update_regset_xstate_info() prototype, which is Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/20211015011539.844565975@linutronix.de
