crypto: aes-ni - Do not sleep when using the FPU Because AES-NI instructions will touch XMM state, corresponding code must be enclosed within kernel_fpu_begin/end, which used preempt_disable/enable. So sleep should be prevented between kernel_fpu_begin/end. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
