In order to support now possible MFNs with 32 (or more) significant bits, two changes are required to the interfaces the Dom0 tools use: The individual page error indication must no longer be or-ed into the passed in MFN (because the bits used by the error indicator may collide with non-zero bits in the MFN), and a replacement for XEN_DOMCTL_getpageframeinfo2 is needed where full-width MFNs can be passed in and the result is being returned in a non-ambiguous way. 1) linux: add new (replacement) mmap-batch ioctl 2) libxc: use new (replacement) mmap-batch ioctl 3) qemu: use new (replacement) mmap-batch ioctl 4) add and use XEN_DOMCTL_getpageframeinfo3 Signed-off-by: Jan Beulich <jbeulich@xxxxxxxxxx>
