From 08739a1555a19236f0473e052c8f460767fb6fd2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 25 Oct 2021 17:32:32 +0100 Subject: [PATCH] arm64/kvm: Fix bitrotted comment for SVE handling in handle_exit.c The comment on the SVE trap handler in handle_exit.c says that it is a placeholder until we support SVE in guests which we now do for both VHE and nVHE cases so we really shouldn't get here in any sort of standard case. Update the comment to be less immediately incorrect, the handling of such a situation is correct.
