Subject: [PATCH 1/1] kvmvapic: add ioport read accessor
Date: Mon,  6 May 2013 15:44:43 +0300	[thread overview]
Message-ID: <0c1cd0ae2a4faabeb948b9a07ea1696e853de174.1367844188.git.gleb@redhat.com> (raw)
In-Reply-To: <cover.1367844188.git.gleb@redhat.com>

From: Marcelo Tosatti <mtosatti@redhat.com>

Necessary since memory region accessor assumes read and write
methods are registered. Otherwise reading I/O port 0x7e segfaults.
