[Xen-devel] [PATCH v2 15/18] mini-os: remap p2m list in case of ballooning

In case of enabled ballooning we must be prepared for a growing p2m list. If the maximum memory size of the domain can't be covered by the actual p2m list remap it to the kernel virtual mapping area and leave enough space at the end. Signed-off-by: Juergen Gross ---
