From 7b90dc40e36e0beb0fdecfef80f33a2e88aced14 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Wed, 2 Dec 2020 13:15:54 +0000 Subject: arm64: uaccess cleanup macro naming Now the uaccess primitives use LDTR/STTR unconditionally, the uao_{ldp,stp,user_alternative} asm macros are misnamed, and have a redundant argument. Let's remove the redundant argument and rename these to user_{ldp,stp,ldst} respectively to clean this up.
