From e513ffd881055c17ccdcc50f279360e2e1bffb40 Mon Sep 17 00:00:00 2001 From: Wang Kefeng Date: Tue, 11 Oct 2022 02:35:07 +0100 Subject: ARM: 9255/1: efi/dump UEFI runtime page tables for ARM UEFI runtime page tables dump only for ARM64 at present, but ARM support EFI and ARM_PTDUMP_DEBUGFS now. Since ARM could potentially execute with a 1G/3G user/kernel split, choosing 1G as the upper limit for UEFI runtime end, with this, we could enable UEFI runtime page tables on ARM.

GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.
