# Merge: 5ba836eb9fdb dfdc6e73cdcf
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Fri Dec 18 11:08:06 2020 -0800
# 
#     Merge tag 's390-5.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
#     
#     Pull more s390 updates from Heiko Carstens:
#      "This is mainly to decouple udelay() and arch_cpu_idle() and simplify
#       both of them.
#     
#       Summary:
#     
#        - Always initialize kernel stack backchain when entering the kernel,
#          so that unwinding works properly.
#     
#        - Fix stack unwinder test case to avoid rare interrupt stack
#          corruption.
#     
#        - Simplify udelay() and just let it busy loop instead of implementing
#          a complex logic.
#     
#        - arch_cpu_idle() cleanup.
#     
#        - Some other minor improvements"
#     
#     * tag 's390-5.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
#       s390/zcrypt: convert comma to semicolon
#       s390/idle: allow arch_cpu_idle() to be kprobed
#       s390/idle: remove raw_local_irq_save()/restore() from arch_cpu_idle()
#       s390/idle: merge enabled_wait() and arch_cpu_idle()
#       s390/delay: remove udelay_simple()
#       s390/irq: select HAVE_IRQ_EXIT_ON_IRQ_STACK
#       s390/delay: simplify udelay
#       s390/test_unwind: use timer instead of udelay
#       s390/test_unwind: fix CALL_ON_STACK tests
#       s390: make calls to TRACE_IRQS_OFF/TRACE_IRQS_ON balanced
#       s390: always clear kernel stack backchain before calling functions
