Hm, the series does not apply cleanly:

 patching file arch/x86/include/asm/fpu/xstate.h
 patching file arch/x86/include/asm/processor.h
 patching file arch/x86/kernel/fpu/init.c
 patching file arch/x86/kernel/fpu/signal.c
 patching file arch/x86/kernel/fpu/xstate.c
 Hunk #4 FAILED at 552.
 1 out of 6 hunks FAILED -- rejects in file arch/x86/kernel/fpu/xstate.c

which suggests that this series isn't against a recent x86 tree, right?

Thanks,
