Subject: [ 38/76] xen/bootup: allow read_tscp call for Xen PV guests.
Date: Thu, 18 Oct 2012 19:47:02 -0700 [thread overview]
Message-ID: <20121019024356.253015982@linuxfoundation.org> (raw)
In-Reply-To: <20121019024350.087156547@linuxfoundation.org>
3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
commit cd0608e71e9757f4dae35bcfb4e88f4d1a03a8ab upstream.
The hypervisor will trap it. However without this patch,
we would crash as the .read_tscp is set to NULL. This patch
fixes it and sets it to the native_read_tscp call.
