[PATCH 3/5] RTC: Add UIP(update in progress) check logic
The UIP(update in progress) is set when RTC is in updating. And the update cycle begins 244us later after UIP is set.

[RFC PATCH 00/35] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
