From 06f8be16be51638c8373f148680d8ec0313c73e2 Mon Sep 17 00:00:00 2001 From: Zenghui Yu Date: Wed, 14 Dec 2022 21:59:43 +0800 Subject: [PATCH] arm64: ptrace: Use ARM64_SME to guard the SME register enumerations commit eb9a85261e297292c4cc44b628c1373c996cedc2 upstream. We currently guard REGSET_{SSVE, ZA} using ARM64_SVE for no good reason. Both enumerations would be pointless without ARM64_SME and create two empty entries in aarch64_regsets[] which would then become part of a process's native regset view (they should be ignored though). Switch to use ARM64_SME instead.
