commit 893256ffae0cf3be34a33a15efe2f2058b4b4fb7
Author: Julien Grall <julien.grall@xxxxxxxxxx>

    xen/arm: Correctly save/restore CNTKCTL_EL1
    
    CNTKCTL_EL1 is used by the guest to control access to the timer from
    userspace.  It therefore needs to be save/restored by Xen as part of
    the VCPU state.
    
    By default Linux on ARM64 exposes the timer to userspace.  Furthermore on
    ARM64, Linux provides helpers in a VDSO (gettimeofday/__do_get_tspec)
    that use the timer counter.  Conversely, during CPU bring up, Xen will
    set CNTKCTL_EL1 to 0 (i.e disallow timer access to the userspace).  As
    a result, currently, if dom0 has 1 VCPU which is migrated to another
    PCPU, init might crash.
    
    Alternatively, a guest (malicious or not) might decide to disable
    access to the timer from userspace.  If the register is not
    save/restored, when a DOM0 VCPU runs again, a similar crash would
    result.
    
    Also, drop CNTKCTL_EL1 initialization in init_timer_interrupt.  Xen
    should let the guest deal with this register.
    
    This is XSA-91 / CVE-2014-3125.
