[Xen-devel] [PATCH v8 09/11] xen: add per-platform defaults for NR_CPUS

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Add specific per-platform defaults for NR_CPUS. Note that the order of
the defaults matter: they need to go first, otherwise the generic
defaults will be applied.

This is done so that Xen builds customized for a specific hardware
platform can have the right NR_CPUS number.
