Roger Pau Monné bc9a5b0497 xen/acpi: only evaluate Processor objects matching online CPUs 
Current Xen Processor driver will evaluate any Processor object on the
ACPI tables regardless of whether the processor is online or not.
Avoid doing so for processors that are not online, as evaluating
methods of processors that are not online could lead to accesses to
invalid memory, and in any case the data that the driver fetches from
the Processor ACPI object only makes sense for processors that are
online.

Note the CPU related data fetched from Xen using XENPF_get_cpuinfo
hypercall could be cached, I leave that as a future optimization.
