  [S390] cio: Use path verification for last path gone after vary off.
  [S390] non-unique constant/macro identifiers.
  [S390] Memory detection fixes.
  [S390] cio: Make ccw_dev_id_is_equal() more robust.
  [S390] Convert extmem spin_lock into a mutex.
  [S390] set KBUILD_IMAGE.
  [S390] lockdep: show held locks when showing a stackdump
  [S390] Add dynamic size check for usercopy functions.
  [S390] Use diag260 for memory size detection.
  [S390] pfault code cleanup.
  [S390] Cleanup memory_chunk array usage.
  [S390] Misaligned wait PSW at memory detection.
  [S390] cpu shutdown rework
  [S390] cpcmd <-> __cpcmd calling issues
  [S390] Bad kexec control page allocation.
  [S390] Reset infrastructure for re-IPL.
