       "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"

      Revert "cpumask: fix checking valid cpu range". · 80493877
      Tetsuo Handa authored
      This reverts commit 78e5a339 ("cpumask: fix checking valid cpu range").
      
      syzbot is hitting WARN_ON_ONCE(cpu >= nr_cpumask_bits) warning at
      cpu_max_bits_warn() [1], for commit 78e5a339 ("cpumask: fix checking
      valid cpu range") is broken.  Obviously that patch hits WARN_ON_ONCE()
      when e.g.  reading /proc/cpuinfo because passing "cpu + 1" instead of
      "cpu" will trivially hit cpu == nr_cpumask_bits condition.
      
      Although syzbot found this problem in linux-next.git on 2022/09/27 [2],
      this problem was not fixed immediately.  As a result, that patch was
      sent to linux.git before the patch author recognizes this problem, and
      syzbot started failing to test changes in linux.git since 2022/10/10
      [3].
      
      Andrew Jones proposed a fix for x86 and riscv architectures [4].  But
      [2] and [5] indicate that affected locations are not limited to arch
      code.  More delay before we find and fix affected locations, less tested
      kernel (and more difficult to bisect and fix) before release.
      
      We should have inspected and fixed basically all cpumask users before
      applying that patch.  We should not crash kernels in order to ask
      existing cpumask users to update their code, even if limited to
      CONFIG_DEBUG_PER_CPU_MAPS=y case.

      clk: tegra: Fix Tegra PWM parent clock · c461c677
      Jon Hunter authored
      Commit 8c193f47 ("pwm: tegra: Optimize period calculation") updated
      the period calculation in the Tegra PWM driver and now returns an error
      if the period requested is less than minimum period supported. This is
      breaking PWM support on various Tegra platforms. For example, on the
      Tegra210 Jetson Nano platform this is breaking the PWM fan support and
      probing the PWM fan driver now fails ...
      
       pwm-fan pwm-fan: Failed to configure PWM: -22
       pwm-fan: probe of pwm-fan failed with error -22
      
      The problem is that the default parent clock for the PWM on Tegra210 is
      a 32kHz clock and is unable to support the requested PWM period.
      
      Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by
      updating the parent clock for the PWM to be the PLL_P.

      clk: qcom: gcc-msm8660: Drop hardcoded fixed board clocks · 8c7bc6ca
      Linus Walleij authored
      These two clocks are now registered in the device tree as fixed clocks,
      causing a regression in the driver as the clock already exists with
      e.g. the name "pxo_board" as the MSM8660 GCC driver probes.
      
      Fix this by just not hard-coding this anymore and everything works
      like a charm.

      clk: mediatek: clk-mux: Add .determine_rate() callback · b05ea331
      AngeloGioacchino Del Regno authored
      Since commit 262ca38f ("clk: Stop forwarding clk_rate_requests
      to the parent"), the clk_rate_request is .. as the title says, not
      forwarded anymore to the parent: this produces an issue with the
      MediaTek clock MUX driver during GPU DVFS on MT8195, but not on
      MT8192 or others.
      
      This is because, differently from others, like MT8192 where all of
      the clocks in the MFG parents tree are of mtk_mux type, but in the
      parent tree of MT8195's MFG clock, we have one mtk_mux clock and
      one (clk framework generic) mux clock, like so:
      
      names: mfg_bg3d -> mfg_ck_fast_ref -> top_mfg_core_tmp (or) mfgpll
      types: mtk_gate ->      mux        ->     mtk_mux      (or) mtk_pll
      
      To solve this issue and also keep the GPU DVFS clocks code working
      as expected, wire up a .determine_rate() callback for the mtk_mux
      ops; for that, the standard clk_mux_determine_rate_flags() was used
      as it was possible to.
      
      This commit was successfully tested on MT6795 Xperia M5, MT8173 Elm,
      MT8192 Spherion and MT8195 Tomato; no regressions were seen.
      
      For the sake of some more documentation about this issue here's the
      trace of it:

      parisc: Fix userspace graphics card breakage due to pgtable special bit · 70be49f2
      Helge Deller authored
      Commit df24e178 ("parisc: Add vDSO support") introduced the vDSO
      support, for which a _PAGE_SPECIAL page table flag was needed.  Since we
      wanted to keep every page table entry in 32-bits, this patch re-used the
      existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break
      if a page is accessed) to store the special bit.
      
      But when graphics card memory is mmapped into userspace, the kernel uses
      vm_iomap_memory() which sets the the special flag. So, with the DMB bit
      set, every access to the graphics memory now triggered a hardware
      exception and segfaulted the userspace program.
      
      Fix this breakage by dropping the DMB bit when writing the page
      protection bits to the CPU TLB.
      
      In addition this patch adds a small optimization: if huge pages aren't
      configured (which is at least the case for 32-bit kernels), then the
      special bit is stored in the hpage (HUGE PAGE) bit instead. That way we
      can skip to reset the DMB bit.
