[PATCH V2] arm64: optimized copy_to_user and copy_from_user assembly code

Hi Feng,

+
+.Lcpy_not_short:
+       /*
+        * We don't much care about the alignment of DST, but we want SRC
+        * to be 128-bit (16 byte) aligned so that we don't cross cache line
+        * boundaries on both loads and stores.
+        */

Could you please tell why is destination alignment not an issue? Is
this a generic implementation that you are referring to or specific to
your platform?
