#     Merge tag 's390-5.5-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 fixes from Vasily Gorbik:
#     
#      - Fix unwinding from irq context of interrupted user process.
#     
#      - Add purgatory build missing symbols check. That helped to uncover and
#        fix missing symbols when built with kasan support enabled.
#     
#      - Couple of ftrace fixes. Avoid broken stack trace and fix recursion
#        loop in function_graph tracer.
#     
#     * tag 's390-5.5-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
#       s390/ftrace: save traced function caller
#       s390/unwind: stop gracefully at user mode pt_regs in irq stack
#       s390/purgatory: do not build purgatory with kcov, kasan and friends
#       s390/purgatory: Make sure we fail the build if purgatory has missing symbols
#       s390/ftrace: fix endless recursion in function_graph tracer
