-Subject: [PATCH 3/3] x86/xen: init %gs very early to avoid page faults with
- stack protector
-
-When running as Xen pv guest %gs is initialized some time after
-C code is started. Depending on stack protector usage this might be
-too late, resulting in page faults.
-
-So setup %gs and MSR_GS_BASE in assembly code already.
