  xor.h was created as asm-um/xor.h rather than include/asm-um/xor.h.
  Fixed.

  A number of bug fixes from UML 2.4.19-6 -
  
  Fixed the net crash seen when slab debugging is enabled
  Fixed PROT_NONE
  Fixed the 'tracing myself' bug seen on umlcoop.  This was caused by
  a number of SIGALRM handlers nesting on the idle thread stack because
  the system was busy enough that UML couldn't clear one before the
  next arrived.
