This series implements the new xl config entry proposed in [1]. Users can use
the new config entry to statically setup shared memory areas among VMs so that

Cheers,
Zhongze Liu (4):
libxl: introduce a new structure to represent static shared memory
regions
libxl:xl: add parsing code to parse "libxl_static_sshm" from xl config
files
x86/p2m : remove checks that forbid adding foreign pages between HVM
guests
libxl: support creation and destruction of static shared memory areas
