+Subject: x86/crypto, x86/fpu: Remove X86_FEATURE_EAGER_FPU #ifdef from the crc32c code
+
+From: Andy Lutomirski <luto@kernel.org>
+
+commit 02f39b2379fb81557ae864ec8f85421c0250c954 upstream.
+
+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.
