[PATCH] Fixes to x86/xen: Provide a Xen PV APIC driver to support patch.

[Konrad Rzeszutek Wilk]

Boris spotted an compile bug (32-bit) and asked some hard questions
that lead me to dig in the 32-bit code in more details.

The patch:
 [PATCH 1/2] x86/xen/apic: Work with UP, non-SMP 32-bit kernels.

fixes the compile issue and also allows us to boot on 32-bit, UP kernels
(dom0 and PV) without any warnings due to the new APIC driver.

The
 [PATCH 2/2] x86/xen/apic: WARN with details.

is more an diagnostic patch that can help in weed out other
bugs in the future.
