File xen.5d3e4ebb5c71477d74a0c503438545a0126d3863.patch of Package xen

From: Anthony PERARD <anthony.perard@citrix.com>
Date: Tue, 1 Jun 2021 16:41:47 +0100
Subject: 5d3e4ebb5c71477d74a0c503438545a0126d3863

libs/foreignmemory: Fix osdep_xenforeignmemory_map prototype

Commit cf8c4d3d13b8 made some preparation to have one day
variable-length-array argument, but didn't declare the array in the
function prototype the same way as in the function definition. And now
GCC 11 complains about it.

Fixes: cf8c4d3d13b8 ("tools/libs/foreignmemory: pull array length argument to map forward")
