[Xen-devel] [PATCH] move MAX_VIRT_CPUS into arch header

[Matt Chapman <matthewc@xxxxxx>]

This patch moves the definition of MAX_VIRT_CPUS from xen.h into
arch-${ARCH}.h (which is included from xen.h).

The initial reason is that the current value of MAX_VIRT_CPUS overflows
the shared_info page on ia64.  Eventually we plan to move the VCPU data
onto separate pages.  However, this is an interim fix and I imagine that
the value of MAX_VIRT_CPUS may indeed be architecture-dependent - for
example, longer bitmasks on a 64-bit machine may make it easier to
support more virtual CPUs.
