Subject: [PATCH] KVM: add X86_LOCAL_APIC dependency
Date: Wed, 4 Oct 2017 12:28:18 +0200 [thread overview]
Message-ID: <20171004102823.1887173-1-arnd@arndb.de> (raw)
The rework of the posted interrupt handling broke building without
support for the local APIC:
ERROR: "boot_cpu_physical_apicid" [arch/x86/kvm/kvm-intel.ko] undefined!
That configuration is probably not particularly useful anyway, so
we can avoid the randconfig failures by adding a Kconfig dependency.
Fixes: 8b306e2f3c41 ("KVM: VMX: avoid double list add with VT-d posted interrupts")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
