[Xen-devel] [xen-unstable PATCH] x86: Increase the default NR_CPUS to 256

[Laszlo Ersek <lersek@xxxxxxxxxx>]

Changeset 21012:ef845a385014 bumped the default to 128 about one and a half 
years ago. Increase it now to 256, as systems with eg. 160 logical CPUs are 
becoming (have become) common.

Thanks for considering.
