Hi Philippe,

this commits looks fishy: the original code already disabled eager mode
reliably because of

if (cpu_has_xsaveopt && eagerfpu != DISABLE)
                        ^^^^^^^^^^^^^^^^^^^

right after the original disabling under I-pipe. Instead, the new code
now keeps xfeatures_mask untouched as it performs the disabling too
late. Could you clarify this?
