Hardware timer context is not properly context switched on ARM

ISSUE DESCRIPTION When running on an ARM platform Xen was not context switching the CNTKCTLEL1 register, which is used by the guest kernel to control access by userspace processes to the hardware timers. This meant that any guest can reconfigure these settings for the entire system. IMPACT A...
