      sysfs: remove redundant __compat_only_sysfs_link_entry_to_kobj fn · 70fbdfef
      Linus Torvalds authored
      Commit 9255782f ("sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj
      function to change the symlink name") made this function a wrapper
      around a new non-underscored function, which is a bit odd.  The normal
      naming convention is the other way around: the underscored function is
      the wrappee, and the non-underscored function is the wrapper.
      
      There's only one single user (well, two call-sites in that user) of the
      more limited double underscore version of this function, so just remove
      the oddly named wrapper entirely and just add the extra NULL argument to
      the user.
      
      I considered just doing that in the merge, but that tends to make
      history really hard to read.

       "Slightly late as I had to rebase mid-week to insert a bug fix:
      
         - A large series from Nick for 64-bit to further rework our exception
           vectors, and rewrite portions of the syscall entry/exit and
           interrupt return in C. The result is much easier to follow code
           that is also faster in general.
      
         - Cleanup of our ptrace code to split various parts out that had
           become badly intertwined with #ifdefs over the years.
      
         - Changes to our NUMA setup under the PowerVM hypervisor which should
           hopefully avoid non-sensical topologies which can lead to warnings
           from the workqueue code and other problems.
      
         - MAINTAINERS updates to remove some of our old orphan entries and
           update the status of others.
      
         - Quite a few other small changes and fixes all over the map.

      Pull clk updates from Stephen Boyd:
       "There's not much to see in the core framework this time around.
        Instead the majority of the diff is the normal collection of driver
        additions for new SoCs and non-critical clk data fixes and updates.
        The framework must be middle aged.
      
        The two biggest directories in the diffstat show that the Qualcomm and
        Unisoc support added a handful of big drivers for new SoCs but that's
        not really the whole story because those new drivers tend to add large
        numbers of lines of clk data. There's a handful of AT91 clk drivers
        added this time around too and a bunch of improvements to drivers like
        the i.MX driver. All around lots of updates and fixes in various clk
        drivers which is good to see.
      
        The core framework has only one real major change which has been
        baking in next for the past couple months. It fixes the framework so
        that it stops caching a clk's phase when the phase clk_op returns an
        error. Before this change we would consider some negative errno as a
        phase and that just doesn't make sense.
      
        Core:
         - Don't show clk phase when it is invalid
      
        New Drivers:
         - Add support for Unisoc SC9863A clks
         - Qualcomm SM8250 RPMh and MSM8976 RPM clks
         - Qualcomm SM8250 Global Clock Controller (GCC) support
         - Qualcomm SC7180 Modem Clock Controller (MSS CC) support
         - EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
         - Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and
           at91sam9g45 SoCs
      
        Updates:
         - GPU GX GDSC support on Qualcomm sc7180
         - Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
         - A series from Anson to convert i.MX8 clock bindings to json-schema
         - Update i.MX pll14xx driver to include new frequency entries for
           pll1443x table, and return error for invalid PLL type
         - Add missing of_node_put() call for a number of i.MX clock drivers
         - Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
           have the flag on its child cpu clock
         - Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
           via CORE_SEL slice, and source from A53 CCM clk root when we need
           to change ARM PLL frequency. Thus, we can support core running
           above 1GHz safely
         - Update i.MX pfdv2 driver to check zero rate and use determine_rate
           for getting the best rate
         - Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for
           imx7d
         - Remove PMC clks from Tegra clk driver
         - Improved clock/reset handling for the Renesas R-Car USB2 Clock
           Selector
         - Conversion to json-schema of the Renesas CPG/MSSR DT bindings
         - Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
         - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and
           M3-N

      Pull tracing updates from Steven Rostedt:
       "New tracing features:
      
         - The ring buffer is no longer disabled when reading the trace file.
      
           The trace_pipe file was made to be used for live tracing and
           reading as it acted like the normal producer/consumer. As the trace
           file would not consume the data, the easy way of handling it was to
           just disable writes to the ring buffer.
      
           This came to a surprise to the BPF folks who complained about lost
           events due to reading. This is no longer an issue. If someone wants
           to keep the old disabling there's a new option "pause-on-trace"
           that can be set.
      
         - New set_ftrace_notrace_pid file. PIDs in this file will not be
           traced by the function tracer.
      
           Similar to set_ftrace_pid, which makes the function tracer only
           trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
           does the reverse.
      
         - New set_event_notrace_pid file. PIDs in this file will cause events
           not to be traced if triggered by a task with a matching PID.
      
           Similar to the set_event_pid file but will not be traced. Note,
           sched_waking and sched_switch events may still be traced if one of
           the tasks referenced by those events contains a PID that is allowed
           to be traced.
      
        Tracing related features:
      
         - New bootconfig option, that is attached to the initrd file.
      
           If bootconfig is on the command line, then the initrd file is
           searched looking for a bootconfig appended at the end.
      
         - New GPU tracepoint infrastructure to help the gfx drivers to get
           off debugfs (acked by Greg Kroah-Hartman)
      
        And other minor updates and fixes"
