[Xen-devel] [PATCH] Automatic bigsmp detection for i386 systems with more than 8 cpus

["Kamble, Nitin A" <nitin.a.kamble@xxxxxxxxx>]

Ian, Keir,
   Linux kernel is able to enable bigsmp mode automatically if SMP i386
kernel finds more than 8 cpus in the system. This patch adds this
missing feature to Xen hypervisor, to enable Xen booting fine on systems
with more than 8 CPUS without any commandline options.

For reference here is the original patch for Linux Kernel.

an-8-cpus-2.patch

Please apply and/or provide comments.
