[Xen-devel] [PATCH 0/4] tools interface changes for supporting MFNs with 32 or more significant bits

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

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
