[PATCH v3 0/2] libelf: small fixes for PVH

Posted by Roger Pau Monne 2 years, 11 months ago

Hello,

A couple of small fixes for PVH loading. The first one is likely not
very relevant, since PVH couldn't be booted anyway with the data in the
__xen_guest section, so it's mostly a cleanup.

Second patch fixes the checks for PVH loading, as in that case physical
addresses must always be used to perform the bound calculations.

Thanks, Roger.
