Linus Torvalds 10de638d8e s390 updates for the 6.4 merge window
- Add support for stackleak feature. Also allow specifying
   architecture-specific stackleak poison function to enable faster
   implementation. On s390, the mvc-based implementation helps decrease
   typical overhead from a factor of 3 to just 25%
 
 - Convert all assembler files to use SYM* style macros, deprecating the
   ENTRY() macro and other annotations. Select ARCH_USE_SYM_ANNOTATIONS
 
 - Improve KASLR to also randomize module and special amode31 code
   base load addresses
 
 - Rework decompressor memory tracking to support memory holes and improve
   error handling
 
 - Add support for protected virtualization AP binding
 
 - Add support for set_direct_map() calls
 
 - Implement set_memory_rox() and noexec module_alloc()
 
 - Remove obsolete overriding of mem*() functions for KASAN
 
 - Rework kexec/kdump to avoid using nodat_stack to call purgatory
 
 - Convert the rest of the s390 code to use flexible-array member instead
   of a zero-length array
 
 - Clean up uaccess inline asm
 
 - Enable ARCH_HAS_MEMBARRIER_SYNC_CORE
 
 - Convert to using CONFIG_FUNCTION_ALIGNMENT and enable
   DEBUG_FORCE_FUNCTION_ALIGN_64B
 
 - Resolve last_break in userspace fault reports
 
 - Simplify one-level sysctl registration
 
 - Clean up branch prediction handling
 
 - Rework CPU counter facility to retrieve available counter sets just
   once
 
 - Other various small fixes and improvements all over the code
