From a517faa902b5a048adbb4d6bbce9509ba5288af3 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Tue, 19 Oct 2021 15:36:44 -0700 Subject: arm64: vdso32: drop test for -march=armv8-a As Arnd points out: gcc-4.8 already supported -march=armv8, and we require gcc-5.1 now, so both this #if/#else construct and the corresponding "cc32-option,-march=armv8-a" check should be obsolete now.
