[kvm-unit-tests PATCH v3 0/3] s390x: css: pv: css test adaptation for PV

[Pierre Morel <pmorel@linux.ibm.com>]

Hi all,

To adapt the CSS I/O tests to protected virtualisation we need
utilities to:

1- allocate the I/O buffers in a private page using (patch 2)
   It must be in a dedicated page to avoid exporting code or
   guest private data to the host.

2- share the I/O buffers with the host (patch 1)
   This patch uses the page allocator reworked by Claudio.

The 2 first patches are the implementation of the tools,
patch 3 is the modification of the css.c test for PV.

regards,
Pierre
