From 9bb003600ed9aabfe33b7330fa7e93acf959e8df Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Tue, 17 Jan 2017 16:10:56 +0000 Subject: arm64: head.S: avoid open-coded adr_l Some places in the kernel open-code sequences using ADRP for a symbol another instruction using a :lo12: relocation for that same symbol. These sequences are easy to get wrong, and more painful to read than is necessary. For these reasons, it is preferable to use the {adr,ldr,str}_l macros for these cases. This patch makes use of adr_l these in head.S, removing an open-coded sequence using adrp.
