#     Merge tag 's390-5.12-6' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull s390 fixes from Heiko Carstens:
#     
#      - fix incorrect dereference of the ext_params2 external interrupt
#        parameter, which leads to an instant kernel crash if a pfault
#        interrupt occurs.
#     
#      - add forgotten stack unwinder support, and fix memory leak for the
#        new machine check handler stack.
#     
#      - fix inline assembly register clobbering due to KASAN code
#        instrumentation.
