Subject: [PATCH v4 09/10] x86/reboot: Unconditionally define cpu_emergency_virt_cb typedef
Date: Thu, 29 Aug 2024 21:35:59 -0700	[thread overview]
Message-ID: <20240830043600.127750-10-seanjc@google.com> (raw)
In-Reply-To: <20240830043600.127750-1-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.
