       "Assorted patches from Miklos.
      
        An interesting part here is /proc/mounts stuff..."
      
      The "/proc/mounts stuff" is using a cursor for keeeping the location
      data while traversing the mount listing.
      
      Also probably worth noting is the addition of faccessat2(), which takes
      an additional set of flags to specify how the lookup is done
      (AT_EACCESS, AT_SYMLINK_NOFOLLOW, AT_EMPTY_PATH).
      
      * 'from-miklos' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
        vfs: add faccessat2 syscall

      Linus Torvalds authored
      Pull arm64 updates from Will Deacon:
       "A sizeable pile of arm64 updates for 5.8.
      
        Summary below, but the big two features are support for Branch Target
        Identification and Clang's Shadow Call stack. The latter is currently
        arm64-only, but the high-level parts are all in core code so it could
        easily be adopted by other architectures pending toolchain support
      
        Branch Target Identification (BTI):
      
         - Support for ARMv8.5-BTI in both user- and kernel-space. This allows
           branch targets to limit the types of branch from which they can be
           called and additionally prevents branching to arbitrary code,
           although kernel support requires a very recent toolchain.
      
         - Function annotation via SYM_FUNC_START() so that assembly functions
           are wrapped with the relevant "landing pad" instructions.
      
         - BPF and vDSO updates to use the new instructions.
      
         - Addition of a new HWCAP and exposure of BTI capability to userspace
           via ID register emulation, along with ELF loader support for the
           BTI feature in .note.gnu.property.
      
         - Non-critical fixes to CFI unwind annotations in the sigreturn
           trampoline.
      
        Shadow Call Stack (SCS):
      
         - Support for Clang's Shadow Call Stack feature, which reserves
           platform register x18 to point at a separate stack for each task
           that holds only return addresses. This protects function return
           control flow from buffer overruns on the main stack.
      
         - Save/restore of x18 across problematic boundaries (user-mode,
           hypervisor, EFI, suspend, etc).
      
         - Core support for SCS, should other architectures want to use it
           too.
      
         - SCS overflow checking on context-switch as part of the existing
           stack limit check if CONFIG_SCHED_STACK_END_CHECK=y.
      
        CPU feature detection:
      
         - Removed numerous "SANITY CHECK" errors when running on a system
           with mismatched AArch32 support at EL1. This is primarily a concern
           for KVM, which disabled support for 32-bit guests on such a system.
      
         - Addition of new ID registers and fields as the architecture has
           been extended.
      
        Perf and PMU drivers:
      
         - Minor fixes and cleanups to system PMU drivers.
      
        Hardware errata:
      
         - Unify KVM workarounds for VHE and nVHE configurations.
      
         - Sort vendor errata entries in Kconfig.
      
        Secure Monitor Call Calling Convention (SMCCC):
      
         - Update to the latest specification from Arm (v1.2).
      
         - Allow PSCI code to query the SMCCC version.
      
        Software Delegated Exception Interface (SDEI):
      
         - Unexport a bunch of unused symbols.
      
         - Minor fixes to handling of firmware data.
      
        Pointer authentication:
      
         - Add support for dumping the kernel PAC mask in vmcoreinfo so that
           the stack can be unwound by tools such as kdump.
      
         - Simplification of key initialisation during CPU bringup.
      
        BPF backend:
      
         - Improve immediate generation for logical and add/sub instructions.
      
        vDSO:
      
         - Minor fixes to the linker flags for consistency with other
           architectures and support for LLVM's unwinder.
      
         - Clean up logic to initialise and map the vDSO into userspace.
      
        ACPI:
      
         - Work around for an ambiguity in the IORT specification relating to
           the "num_ids" field.
      
         - Support _DMA method for all named components rather than only PCIe
           root complexes.
      
         - Minor other IORT-related fixes.
      
        Miscellaneous:
      
         - Initialise debug traps early for KGDB and fix KDB cacheflushing
           deadlock.
      
         - Minor tweaks to early boot state (documentation update, set
           TEXT_OFFSET to 0x0, increase alignment of PE/COFF sections).
      
         - Refactoring and cleanup"

         - Add Zhaoxin CPU support
      
         - Misc fixes and cleanups
      
        Tooling changes:
      
         - perf record:
      
           Introduce '--switch-output-event' to use arbitrary events to be
           setup and read from a side band thread and, when they take place a
           signal be sent to the main 'perf record' thread, reusing the core
           for '--switch-output' to take perf.data snapshots from the ring
           buffer used for '--overwrite', e.g.:
      
      	# perf record --overwrite -e sched:* \
      		      --switch-output-event syscalls:*connect* \
      		      workload
      
           will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
           connect syscalls.
      
           Add '--num-synthesize-threads' option to control degree of
           parallelism of the synthesize_mmap() code which is scanning
           /proc/PID/task/PID/maps and can be time consuming. This mimics
           pre-existing behaviour in 'perf top'.
      
         - perf bench:
      
           Add a multi-threaded synthesize benchmark and kallsyms parsing
           benchmark.
      
         - Intel PT support:
      
           Stitch LBR records from multiple samples to get deeper backtraces,
           there are caveats, see the csets for details.
      
           Allow using Intel PT to synthesize callchains for regular events.
      
           Add support for synthesizing branch stacks for regular events
           (cycles, instructions, etc) from Intel PT data.
      
        Misc changes:
      
         - Updated perf vendor events for power9 and Coresight.
      
         - Add flamegraph.py script via 'perf flamegraph'
      
         - Misc other changes, fixes and cleanups - see the Git log for details
      
        Also, since over the last couple of years perf tooling has matured and
        decoupled from the kernel perf changes to a large degree, going
        forward Arnaldo is going to send perf tooling changes via direct pull
