commit: cd0608e71e9757f4dae35bcfb4e88f4d1a03a8ab From: Konrad Rzeszutek Wilk <[email protected]> Date: Wed, 10 Oct 2012 13:30:47 -0400 Subject: xen/bootup: allow read_tscp call for Xen PV guests.
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.
