[Xen-devel] [patch] hvmloader: Reserve ioport ranges for expanded PHP

[Simon Horman <horms@xxxxxxxxxxxx>]

My recent patch "Allow any unused PCI > device to be used for pass-through"
and the follow-up "qemu-xen: pass-through: Allow slots 1e and 1f to be used"
expand the number of PHP slots from 2 to 32. Accordingly the ioport space
required has expanded by 30 bytes.

This patch should be appropriate for 3.4
