[Xen-devel] [PATCH v2 for-4.7 5/6] xen/xsplice: add ELFOSABI_FREEBSD as a supported OSABI for payloads

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

The calling convention used by the FreeBSD ELF OSABI is exactly the same as
the the one defined by System V, so payloads with a FreeBSD OSABI should be
accepted by the xsplice machinery.
