Subject: [PATCH v9 05/16] KVM: Guard mmu_notifier specific code with CONFIG_MMU_NOTIFIER
Date: Tue, 03 Jul 2012 05:00:05 -0400	[thread overview]
Message-ID: <20120703090005.27746.57699.stgit@ubuntu> (raw)
In-Reply-To: <20120703085841.27746.82730.stgit@ubuntu>

From: Marc Zyngier <marc.zyngier@arm.com>

In order to avoid compilation failure when KVM is not compiled in,
guard the mmu_notifier specific sections with both CONFIG_MMU_NOTIFIER
and KVM_ARCH_WANT_MMU_NOTIFIER, like it is being done in the rest of
the KVM code.
