Subject: [RFC][PATCH 9/12] KVM: introduce a wrapper function of set_bit_user_non_atomic()
Date: Tue, 4 May 2010 22:06:20 +0900	[thread overview]
Message-ID: <20100504220620.97e90535.takuya.yoshikawa@gmail.com> (raw)
In-Reply-To: <20100504215645.6448af8f.takuya.yoshikawa@gmail.com>

This is not to break the build for other architectures than x86 and ppc.
