SLOF (guest firmware # used by QEMU) currently doesn't do this so the zImage is not aware of # the initrd location. This can result in initrd corruption either # though the zImage extracting the vmlinux over the initrd, or by the # vmlinux overwriting the initrd when relocating itself. # # QEMU does put the linux,initrd-start and linux,initrd-end properties # into the devicetree to vmlinux to find the initrd. So we can work # around the problem by also looking for those properties in the zImage. # # Cc: stable@vger.kernel.org # Signed-off-by: Oliver O'Halloran # Signed-off-by: Michael Ellerman # Link:
