Because the crashkernel memory is not included in the page tables for suspend/resume it is not included in the suspend image. Therefore after resume the resumed system does no longer contain the pre-loaded kdump kernel and when kdump is triggered it fails. This patch adds a PM notifier that creates the page tables before suspend is done and removes them for resume. This ensures that the kdump kernel is included in the suspend image.
