Pull x86 fixes from Borislav Petkov:
 "Two more urgent FPU fixes:

   - prevent unprivileged userspace from reinitializing supervisor
     states

   - prepare init_fpstate, which is the buffer used when initializing
     FPU state, properly in case the skip-writing-state-components
     XSAVE* variants are used"
