      Pull s390 fixes from Heiko Carstens:
      
       - Add various missing READ_ONCE() to cmpxchg() loops prevent the
         compiler from potentially generating incorrect code. This includes a
         rather large change to the s390 specific hardware sampling code and
         its current use of cmpxchg_double().
      
         Do the fix now to get it out of the way of Peter Zijlstra's
         cmpxchg128() work, and have something that can be backported. The
         added new code includes a private 128 bit cmpxchg variant which will
         be removed again after Peter's rework is available. Also note that
         this 128 bit cmpxchg variant is used to implement 128 bit
         READ_ONCE(), while strictly speaking it wouldn't be necessary, and
         _READ_ONCE() should also be sufficient; even though it isn't obvious
         for all converted locations that this is the case. Therefore use this
         implementation for for the sake of clarity and consistency for now.
      
       - Fix ipl report address handling to avoid kdump failures/hangs.
      
       - Fix misuse of #(el)if in kernel decompressor.
      
       - Define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36,
         caused by the recently changed discard behaviour.
      
       - Make sure _edata and _end symbols are always page aligned.
      
       - The current header guard DEBUG_H in one of the s390 specific header
         files is too generic and conflicts with the ath9k wireless driver.
         Add an _ASM_S390_ prefix to the guard to make it unique.
      
       - Update defconfigs.
