[Qemu-devel] [PATCH] exec, Fix guest memory access. |
Date: |

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.
