Xen devel - Apr 2012 - [PULL BUILD FIX] build xc_hvm_inject_msi on Xen < 4.2

Anthony,
please pull:

git://xenbits.xen.org/people/sstabellini/qemu-dm.git build_fix


this small patch series fixes the build breakage introduced by
f1dbf015dfb0aa7f66f710a1f1bc58b662951de2 with Xen < 4.2.

The problem is that xc_hvm_inject_msi is only defined from Xen 4.2
onwards so we need to provide a compatibility function for older Xen
versions.

Stefano Stabellini (2):
      xen,configure: detect Xen 4.2
      xen: add a dummy xc_hvm_inject_msi for Xen < 4.2
