Subject: [PATCH 4/4] 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.
