From 29589ca09a74cfc0c50ad002e298bf4b8e69e0bd Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 31 May 2022 09:49:24 +0100 Subject: ARM: 9208/1: entry: add .ltorg directive to keep literals in range LKP reports a build issue on Clang, related to a literal load of __current issued through the ldr_va macro. This turns out to be due to the fact that group relocations are disabled when CONFIG_COMPILE_TEST=y, which means that the ldr_va macro resolves to a pair of LDR instructions, the first one being a literal load issued too far from its literal pool. Due to the introduction of a couple of new uses of this macro in commit 508074607c7b95b2 ("ARM: 9195/1: entry: avoid explicit literal loads"), the literal pools end up getting rearranged in a way that causes the literal for __current to go out of range. Let's fix this up by putting a .ltorg directive in a suitable place in the code.
