Subject: xen: syswrap XENMEM_machphys_compat_mfn_list
X-Git-Tag: svn/VALGRIND_3_11_0~265
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a8a96401984fed5f9a1298d2364e9e15a7587df;p=thirdparty%2Fvalgrind.git

xen: syswrap XENMEM_machphys_compat_mfn_list

XENMEM_machphys_compat_mfn_list is functionally identical to
XENMEM_machphys_mfn_list but returns a different list from Xen.
