This patch updates percpu related symbols in xen such that percpu
symbols are unique and don't clash with local symbols. This serves
two purposes of decreasing the possibility of global percpu symbol
collision and allowing dropping per_cpu__ prefix from percpu symbols.
* arch/x86/xen/smp.c, arch/x86/xen/time.c, arch/ia64/xen/irq_xen.c:
add xen_ prefix to percpu variables
* arch/ia64/xen/time.c: add xen_ prefix to percpu variables, drop
processed_ prefix and make them static
Partly based on Rusty Russell's "alloc_percpu: rename percpu vars
which cause name clashes" patch.

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons. After more than two years it's
time to remove them finally.
This patch cleans up one of the remaining users. When all such patches
hit mainline we can remove the defines and typedefs finally.
Impact: cleanup
Convert the last remaining users and remove the typedef.
