    Pull x86 fix from Thomas Gleixner:
     "A fix and an email address update:
    
       - Prevent FPU state corruption.
    
         The condition in irq_fpu_usable() grants FPU usage when the FPU is
         not used in the kernel. That's just wrong as it does not take the
         fpregs_lock()'ed regions into account. If FPU usage happens within
         such a region from interrupt context, then the FPU state gets
         corrupted.
    
         That's a long standing bug, which got unearthed by the recent
         changes to the random code.
