Message-Id: <20121019031304.675393314@linuxfoundation.org> Date: Thu, 18 Oct 2012 20:16:34 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, alan@...rguk.ukuu.org.uk, Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> Subject: [ 11/37] xen/bootup: allow read_tscp call for Xen PV guests. 3.0-stable review patch. If anyone has any objections, please let me know. ------------------ From: Konrad Rzeszutek Wilk <konrad.wilk@...cle.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.
