From c8a91428941b912d66e13a2719fe6ac670150d69 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 4 Apr 2022 23:38:28 +0200 Subject: ARM: PXA: fix multi-cpu build of xsc3 On a kernel that includes both ARMv4 and XScale support, the copypage function fails to build with invalid instructions. Since these are only called on an actual XScale processor, annotate the assembly with the correct .arch directive.
