xen/privcmd: add PRIVCMD_MMAPBATCH_V2 ioctl
PRIVCMD_MMAPBATCH_V2 extends PRIVCMD_MMAPBATCH with an additional field for reporting the error code for every frame that could not be mapped. libxc prefers PRIVCMD_MMAPBATCH_V2 over PRIVCMD_MMAPBATCH. Also expand PRIVCMD_MMAPBATCH to return appropriate error-encoding top nibble in the mfn array. Signed-off-by:David Vrabel <david.vrabel@citrix.com> Signed-off-by:
