Yu-cheng Yu 1fc2b67b43 x86/fpu/xstate: Fix __fpu_restore_sig() for XSAVES ... When the kernel is using XSAVES compacted format, we cannot do __copy_from_user() from a signal frame, which has standard-format data. Fix it by using copyin_to_xsaves(), which converts between formats and filters out all supervisor states that we do not allow userspace to write.
