From 01dd95827726534230d8f03f7e6faafe24e49260 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Tue, 3 Nov 2009 10:55:20 -0500 Subject: crypto: ghash-intel - Fix irq_fpu_usable usage When renaming kernel_fpu_using to irq_fpu_usable, the semantics of the function is changed too, from mesuring whether kernel is using FPU, that is, the FPU is NOT available, to measuring whether FPU is usable, that is, the FPU is available. But the usage of irq_fpu_usable in ghash-clmulni-intel_glue.c is not changed accordingly. This patch fixes this.
