[Xen-devel] [PATCH]x86: Increase the default NR_CPUS to 128.

["Zhang, Xiantao" <xiantao.zhang@xxxxxxxxx>]

x86: Increase the default NR_CPUS to 128.

We have newer systems which have more than 64 CPUs, and users
often complain some cpus can't be waken up when play with Xen.
Certainly, MAX_PHYS_CPUS option also can support more CPUs, but
it is still inconvenient for them, so change the default value to 128.
