Thomas Gleixner daddee2473 x86/fpu: Mop up xfeatures_mask_uabi() ... Use the new fpu_user_cfg to retrieve the information instead of xfeatures_mask_uabi() which will be no longer correct when dynamically enabled features become available. Using fpu_user_cfg is appropriate when setting XCOMP_BV in the init_fpstate since it has space allocated for "max_features". But, normal fpstates might only have space for default xfeatures. Since XRSTOR* derives the format of the XSAVE buffer from XCOMP_BV, this can lead to XRSTOR reading out of bounds. So when copying actively used fpstate, simply read the XCOMP_BV features bits directly out of the fpstate instead.
