Subject:[Xen-ia64-devel] [PATCH] change layout of p2m table from xenheap to domheap

Hi,

Current xen can not fully utilize 64GB memory since xenheap is exhausted by p2m tables.

This patch changes the layout of p2m table from xenheap to domheap. The side effect is subtle performance down due to TLB miss.

A new boot option 'p2m_xenheap' enables the previous setting that p2m table is allocated in xenheap. I dare to change the default for the future.

If there are no objections, please apply.

Thanks, Kouya
