Subject: [PATCH v7 02/12] KVM: Guard mmu_notifier specific code with CONFIG_MMU_NOTIFIER
Date: Mon, 12 Mar 2012 02:52:03 -0400	[thread overview]
Message-ID: <20120312065203.8074.52925.stgit@ubuntu> (raw)
In-Reply-To: <20120312065134.8074.36949.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.
