See patch 4 for details of the problem.  Other patches fix other errors found
while investigating.

This is only the hypervisor side of the change for now, because I want
agreement before starting to untangle the mess which is libxc's helpers for
this.

Also a disaster is Linux's sysfs handling for these.  In several places it
makes a heap allocation for a pointer (or two) sized object.

Andrew Cooper (4):
  public/version: Change xen_feature_info to have a fixed size
  xen/version: Drop compat/kernel.c
  xen/version: Drop bogus return values for XENVER_platform_parameters
  xen/version: Introduce non-truncating XENVER_* subops
