Subject: [PATCH 0/2] KVM: VMX: Make VMREAD error trampoline noinstr friendly
Date: Fri, 21 Jul 2023 16:56:35 -0700 [thread overview]
Message-ID: <20230721235637.2345403-1-seanjc@google.com> (raw)
Add another trampoline for the CONFIG_CC_HAS_ASM_GOTO_OUTPUT=n VMREAD error
path in order to enable instrumentation, i.e. to make objtool happy, before
calling pr_warn_ratelimited().
