      s390/kdump: Add PM notifier for kdump · b66ac63e
      Michael Holzheu authored
      For s390 the page table mapping for the crashkernel memory is removed to
      protect the pre-loaded kdump kernel and ramdisk. 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.
