Linus Torvalds 27b5d61c0c 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.
