Subject: [PATCH 1/9] x86/crypto: Remove X86_FEATURE_EAGER_FPU ifdef from the crc32c code
Date: Tue,  4 Oct 2016 20:34:30 -0400	[thread overview]
Message-ID: <1475627678-20788-2-git-send-email-riel@redhat.com> (raw)
In-Reply-To: <1475627678-20788-1-git-send-email-riel@redhat.com>

From: Rik van Riel <riel@redhat.com>

>From : Andy Lutomirski <luto@kernel.org>

The crypto code was checking both use_eager_fpu() and
defined(X86_FEATURE_EAGER_FPU).  The latter was nonsensical, so
remove it.  This will avoid breakage when we remove
X86_FEATURE_EAGER_FPU.
