Subject: [PATCH 09/23] x86/srso: Print mitigation for retbleed IBPB case
Date:   Fri, 25 Aug 2023 00:01:40 -0700
Message-ID: <1f2f2257abc4047c707d0b8dbbd8e796730597f6.1692919072.git.jpoimboe@kernel.org>

Precedence: bulk

When overriding the requested mitigation with IBPB due to retbleed=ibpb,
print the mitigation in the usual format instead of a custom error
message.
