From d6905849f87596f94c2778c8337697df486de43c Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 24 Jan 2022 19:16:58 +0100 Subject: ARM: assembler: define a Kconfig symbol for group relocation support Nathan reports the group relocations go out of range in pathological cases such as allyesconfig kernels, which have little chance of actually booting but are still used in validation. So add a Kconfig symbol for this feature, and make it depend on !COMPILE_TEST.
