-Subject: [PATCH] crypto: poly1305-x86_64 - Use XORL r32,32
-
-commit 7dfd1e01b3dfc13431b1b25720cf2692a7e111ef upstream.
-
-x86_64 zero extends 32bit operations, so for 64bit operands,
-XORL r32,r32 is functionally equal to XORQ r64,r64, but avoids
-a REX prefix byte when legacy registers are used.
