      Pull more random number generator updates from Jason Donenfeld:
       "This time with some large scale treewide cleanups.
      
        The intent of this pull is to clean up the way callers fetch random
        integers. The current rules for doing this right are:
      
         - If you want a secure or an insecure random u64, use get_random_u64()
      
         - If you want a secure or an insecure random u32, use get_random_u32()
      
           The old function prandom_u32() has been deprecated for a while
           now and is just a wrapper around get_random_u32(). Same for
           get_random_int().
      
         - If you want a secure or an insecure random u16, use get_random_u16()
      
         - If you want a secure or an insecure random u8, use get_random_u8()
      
         - If you want secure or insecure random bytes, use get_random_bytes().
      
           The old function prandom_bytes() has been deprecated for a while
           now and has long been a wrapper around get_random_bytes()
      
         - If you want a non-uniform random u32, u16, or u8 bounded by a
           certain open interval maximum, use prandom_u32_max()
      
           I say "non-uniform", because it doesn't do any rejection sampling
           or divisions. Hence, it stays within the prandom_*() namespace, not
           the get_random_*() namespace.
      
           I'm currently investigating a "uniform" function for 6.2. We'll see
           what comes of that.
      
        By applying these rules uniformly, we get several benefits:
      
         - By using prandom_u32_max() with an upper-bound that the compiler
           can prove at compile-time is ≤65536 or ≤256, internally
           get_random_u16() or get_random_u8() is used, which wastes fewer
           batched random bytes, and hence has higher throughput.
      
         - By using prandom_u32_max() instead of %, when the upper-bound is
           not a constant, division is still avoided, because
           prandom_u32_max() uses a faster multiplication-based trick instead.
      
         - By using get_random_u16() or get_random_u8() in cases where the
           return value is intended to indeed be a u16 or a u8, we waste fewer
           batched random bytes, and hence have higher throughput.
      
        This series was originally done by hand while I was on an airplane
        without Internet. Later, Kees and I worked on retroactively figuring
        out what could be done with Coccinelle and what had to be done
        manually, and then we split things up based on that.
      
        So while this touches a lot of files, the actual amount of code that's
        hand fiddled is comfortably small"

      Pull more perf tools updates from Arnaldo Carvalho de Melo:
      
       - Use BPF CO-RE (Compile Once, Run Everywhere) to support old kernels
         when using bperf (perf BPF based counters) with cgroups.
      
       - Support HiSilicon PCIe Performance Monitoring Unit (PMU), that
         monitors bandwidth, latency, bus utilization and buffer occupancy.
      
         Documented in Documentation/admin-guide/perf/hisi-pcie-pmu.rst.
      
       - User space tasks can migrate between CPUs, so when tracing selected
         CPUs, system-wide sideband is still needed, fix it in the setup of
         Intel PT on hybrid systems.
      
       - Fix metricgroups title message in 'perf list', it should state that
         the metrics groups are to be used with the '-M' option, not '-e'.
      
       - Sync the msr-index.h copy with the kernel sources, adding support for
         using "AMD64_TSC_RATIO" in filter expressions in 'perf trace' as well
         as decoding it when printing the MSR tracepoint arguments.
      
       - Fix program header size and alignment when generating a JIT ELF in
         'perf inject'.
      
       - Add multiple new Intel PT 'perf test' entries, including a jitdump
         one.
      
       - Fix the 'perf test' entries for 'perf stat' CSV and JSON output when
         running on PowerPC due to an invalid topology number in that arch.
      
       - Fix the 'perf test' for arm_coresight failures on the ARM Juno
         system.
      
       - Fix the 'perf test' attr entry for PERF_FORMAT_LOST, adding this
         option to the or expression expected in the intercepted
         perf_event_open() syscall.
      
       - Add missing condition flags ('hs', 'lo', 'vc', 'vs') for arm64 in the
         'perf annotate' asm parser.
      
       - Fix 'perf mem record -C' option processing, it was being chopped up
         when preparing the underlying 'perf record -e mem-events' and thus
         being ignored, requiring using '-- -C CPUs' as a workaround.
      
       - Improvements and tidy ups for 'perf test' shell infra.
      
       - Fix Intel PT information printing segfault in uClibc, where a NULL
         format was being passed to fprintf.

      Pull more clk updates from Stephen Boyd:
       "This is the final part of the clk patches for this merge window.
      
        The clk rate range series needed another week to fully bake. Maxime
        fixed the bug that broke clk notifiers and prevented this from being
        included in the first pull request. He also added a unit test on top
        to make sure it doesn't break so easily again. The majority of the
        series fixes up how the clk_set_rate_*() APIs work, particularly
        around when the rate constraints are dropped and how they move around
        when reparenting clks. Overall it's a much needed improvement to the
        clk rate range APIs that used to be pretty broken if you looked
        sideways.
      
        Beyond the core changes there are a few driver fixes for a compilation
        issue or improper data causing clks to fail to register or have the
        wrong parents. These are good to get in before the first -rc so that
        the system actually boots on the affected devices"
