[Xen-devel] [PATCH] exec, Fix guest memory access.

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

In cpu_physical_memory_rw, a change has been introduced and qemu_get_ram_ptr is
no longuer called with the ram addr we want to access, but only with the
section address. This patch fixes this. (All other call to qemu_get_ram_ptr are
already called with the right address.)

This patch fixes Xen guest.
