Linus Torvalds c7a5238ef6 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.
