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.
- Josh wants to use his kernel.org email address"
