From 4e6e8c2b757f382684abc4765202cd25c221dea1 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 4 Oct 2024 21:26:29 +0100 Subject: binfmt_elf: Wire up AT_HWCAP3 at AT_HWCAP4 AT_HWCAP3 and AT_HWCAP4 were recently defined for use on PowerPC in commit 3281366a8e79 ("uapi/auxvec: Define AT_HWCAP3 and AT_HWCAP4 aux vector, entries"). Since we want to start using AT_HWCAP3 on arm64 add support for exposing both these new hwcaps via binfmt_elf.
