Subject: [PATCH 1/4] x86/reboot: Unconditionally define cpu_emergency_virt_cb typedef
Date: Thu, 25 Apr 2024 16:39:48 -0700 [thread overview]
Message-ID: <20240425233951.3344485-2-seanjc@google.com> (raw)
In-Reply-To: <20240425233951.3344485-1-seanjc@google.com>
Define cpu_emergency_virt_cb even if the kernel is being built without KVM
support so that KVM can reference the typedef in asm/kvm_host.h without
needing yet more #ifdefs.
No functional change intended.
