    Linus Torvalds authored
    Pull s390 updates from Vasily Gorbik:
    
     - 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
