      Pull perf tooling updates from Ingo Molnar:
       "perf.data:
      
         - Streaming compression of perf ring buffer into
           PERF_RECORD_COMPRESSED user space records, resulting in ~3-5x
           perf.data file size reduction on variety of tested workloads what
           saves storage space on larger server systems where perf.data size
           can easily reach several tens or even hundreds of GiBs, especially
           when profiling with DWARF-based stacks and tracing of context
           switches.
      
        perf record:
      
         - Improve -user-regs/intr-regs suggestions to overcome errors
      
        perf annotate:
      
         - Remove hist__account_cycles() from callback, speeding up branch
           processing (perf record -b)
      
        perf stat:
      
         - Add a 'percore' event qualifier, e.g.: -e
           cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
           both hardware threads in a core.
      
           We can already do this with --per-core, but it's often useful to do
           this together with other metrics that are collected per hardware
           thread.
      
           I.e. now its possible to do this per-event, and have it mixed with
           other events not aggregated by core.
      
        arm64:
      
         - Map Brahma-B53 CPUID to cortex-a53 events.
      
         - Add Cortex-A57 and Cortex-A72 events.
      
        csky:
      
         - Add DWARF register mappings for libdw, allowing --call-graph=dwarf
           to work on the C-SKY arch.
      
        x86:
      
         - Add support for recording and printing XMM registers, available,
           for instance, on Icelake.
      
         - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
           support. UPI replaced the Intel QuickPath Interconnect (QPI) in
           Xeon Skylake-SP.
      
        Intel PT:
      
         - Fix instructions sampling rate.
      
         - Timestamp fixes.
      
         - Improve exported-sql-viewer GUI, allowing, for instance, to
           copy'n'paste the trees, useful for e-mailing"

        target for the 5.2 merge window. Most of the patches are cleanups, but
        there are a handful of user-visible changes:
      
         - The nosmp and nr_cpus command-line arguments are now supported,
           which work like normal.
      
         - The SBI console no longer installs itself as a preferred console,
           we rely on standard mechanisms (/chosen, command-line, hueristics)
           instead.
      
         - sfence_remove_sfence_vma{,_asid} now pass their arguments along to
           the SBI call.
      
         - Modules now support BUG().
      
         - A missing sfence.vma during boot has been added. This bug only
           manifests during boot.
      
         - The arch/riscv support for SiFive's L2 cache controller has been
           merged, which should un-block the EDAC framework work.
      
        I've only tested this on QEMU again, as I didn't have time to get
        things running on the Unleashed. The latest master from this morning
