Merge tag 's390-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
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 * tag 's390-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (118 commits) s390/stackleak: provide fast __stackleak_poison() implementation stackleak: allow to specify arch specific stackleak poison function s390: select ARCH_USE_SYM_ANNOTATIONS s390/mm: use VM_FLUSH_RESET_PERMS in module_alloc() s390: wire up memfd_secret system call s390/mm: enable ARCH_HAS_SET_DIRECT_MAP s390/mm: use BIT macro to generate SET_MEMORY bit masks s390/relocate_kernel: adjust indentation s390/relocate_kernel: use SYM* macros instead of ENTRY(), etc. s390/entry: use SYM* macros instead of ENTRY(), etc. s390/purgatory: use SYM* macros instead of ENTRY(), etc. s390/kprobes: use SYM* macros instead of ENTRY(), etc. s390/reipl: use SYM* macros instead of ENTRY(), etc. s390/head64: use SYM* macros instead of ENTRY(), etc. s390/earlypgm: use SYM* macros instead of ENTRY(), etc. s390/mcount: use SYM* macros instead of ENTRY(), etc. s390/crc32le: use SYM* macros instead of ENTRY(), etc. s390/crc32be: use SYM* macros instead of ENTRY(), etc. s390/crypto,chacha: use SYM* macros instead of ENTRY(), etc. s390/amode31: use SYM* macros instead of ENTRY(), etc. ...
