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"
