Linus Torvalds 24cb958695 s390 updates for 5.20 merge window
- Rework copy_oldmem_page() callback to take an iov_iter.
   This includes few prerequisite updates and fixes to the
   oldmem reading code.
 
 - Rework cpufeature implementation to allow for various CPU feature
   indications, which is not only limited to hardware capabilities,
   but also allows CPU facilities.
 
 - Use the cpufeature rework to autoload Ultravisor module when CPU
   facility 158 is available.
 
 - Add ELF note type for encrypted CPU state of a protected virtual CPU.
   The zgetdump tool from s390-tools package will decrypt the CPU state
   using a Customer Communication Key and overwrite respective notes to
   make the data accessible for crash and other debugging tools.
 
 - Use vzalloc() instead of vmalloc() + memset() in ChaCha20 crypto test.
 
 - Fix incorrect recovery of kretprobe modified return address in stacktrace.
 
 - Switch the NMI handler to use generic irqentry_nmi_enter() and
   irqentry_nmi_exit() helper functions.
 
 - Rework the cryptographic Adjunct Processors (AP) pass-through design
   to support dynamic changes to the AP matrix of a running guest as well
   as to implement more of the AP architecture.
 
 - Minor boot code cleanups.
 
 - Grammar and typo fixes to hmcdrv and tape drivers.
