From 150c7e85526e80474b87004f4b420e8834fdeb43 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Sun, 29 Mar 2009 15:39:02 +0800 Subject: crypto: fpu - Add template for blkcipher touching FPU Blkcipher touching FPU need to be enclosed by kernel_fpu_begin() and kernel_fpu_end(). If they are invoked in cipher algorithm implementation, they will be invoked for each block, so that performance will be hurt, because they are "slow" operations. This patch implements "fpu" template, which makes these operations to be invoked for each request.
