Yann Droneaud ebf2d2689d perf/x86: Fix copy_from_user_nmi() return if range is not ok ... Commit 0a196848ca ("perf: Fix arch_perf_out_copy_user default"), changes copy_from_user_nmi() to return the number of remaining bytes so that it behave like copy_from_user(). Unfortunately, when the range is outside of the process memory, the return value is still the number of byte copied, eg. 0, instead of the remaining bytes. As all users of copy_from_user_nmi() were modified as part of commit 0a196848ca, the function should be fixed to return the total number of bytes if range is not correct.
