[Xen-devel] [PATCH for v1.6] pc: Fix initialization of the ram_memory variable.

In some cases (Xen), it will not be initialized before to be used. This
leads to segv.

Signed-off-by: Anthony PERARD <anthony.perard@xxxxxxxxxx>


It works with this simple initialization to NULL, but would it be
necessary (or better) to assign a proper value to this variables ?
