[Xen-devel] [PATCH v2] xen: Allow CPU to be counted than currently "plugged".

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Under Xen, SeaBIOS can count more CPU than there should be. This patch
will allow more CPU to come up instead of going to infinite loop waiting
for the CPU counter to be decremented.
