[Xen-devel] [Patch] Qemu map cache

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

On IA32 host or IA32 PAE host, at present, generally, we can't create an
HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.
