-Subject: [PATCH] crypto: curve25519-x86_64 - Use XORL r32,32
-
-commit db719539fd3889836900bf912755aa30a5985e9a upstream.
-
-x86_64 zero extends 32bit operations, so for 64bit operands,
-XORL r32,r32 is functionally equal to XORL r64,r64, but avoids
-a REX prefix byte when legacy registers are used.
