Subject: [GIT PULL] s390 updates for 5.15 merge window
Hi Linus,
please pull s390 updates for the 5.15 merge window. There are some small
changes outside of s390, but everything has been agreed on (see provided
links below).
Thanks,
Heiko
The following changes since commit ff1176468d368232b684f75e82563369208bc371:
Linux 5.14-rc3 (2021-07-25 15:35:14 -0700)
are available in the Git repository at:

s390: remove SCHED_CORE from defconfigs (2021-08-30 12:55:05 +0200)
----------------------------------------------------------------
s390 updates for 5.15 merge window
- Improve ftrace code patching so that stop_machine is not required anymore.
This requires a small common code patch acked by Steven Rostedt:
https://lore.kernel.org/linux-s390/20210730220741.4da6fdf6@oasis.local.home/
- Enable KCSAN for s390. This comes with a small common code change to fix a
compile warning. Acked by Marco Elver:
https://lore.kernel.org/r/20210729142811.1309391-1-hca@linux.ibm.com/
- Add KFENCE support for s390. This also comes with a minimal x86 patch from
Marco Elver who said also this can be carried via the s390 tree:
https://lore.kernel.org/linux-s390/YQJdarx6XSUQ1tFZ@elver.google.com/
- More changes to prepare the decompressor for relocation.
- Enable DAT also for CPU restart path.
- Final set of register asm removal patches; leaving only three locations where
needed and sane.
- Add NNPA, Vector-Packed-Decimal-Enhancement Facility 2, PCI MIO support to
hwcaps flags.
- Cleanup hwcaps implementation.
- Add new instructions to in-kernel disassembler.
- Various QDIO cleanups.
- Add SCLP debug feature.
- Various other cleanups and improvements all over the place.
