Patch 1 is a long outstanding bug, and hopefully still qualifies for 4.20 at
this point.

Patches 2 and 3 probably don't, seeing as I can't seem to get UBSAN working
for PPC (for which patch 3 at least would be a prerequisite to compile).  They
can wait until 4.21 now.

Andrew Cooper (4):
  ARM32/traps: Fix do_trap_undefined_instruction()'s detection of kernel text
  ARM: Fix register constraints in run_in_exception_handler()
  xen: Centralise the declaration of dump_execution_state()
  [BROKEN] PPC: Activate UBSAN in testing
