We were registering our slave MDIO bus with OF and doing so with
assigning the newly created slave_mii_bus of_node to the master MDIO bus
controller node. This is a bad thing to do for a number of reasons:

- we are completely lying about the slave MII bus is arranged and yet we
  still want to control which MDIO devices it probes. It was attempted
  before to play tricks with the bus_mask to perform that:
  https://www.spinics.net/lists/netdev/msg429420.html but the approach
  was rightfully rejected

- the device_node reference counting is messed up and we are effectively
  doing a double probe on the devices we already probed using the
  master, this messes up all resources reference counts (such as clocks)

The proper fix for this as indicated by David in his reply to the
thread above is to use a platform data style registration so as to
control exactly which devices we probe:
https://www.spinics.net/lists/netdev/msg430083.html

By using mdiobus_register(), our slave_mii_bus->phy_mask value is used
as intended, and all the PHY addresses that must be redirected towards
our slave MDIO bus is happening while other addresses get redirected
towards the master MDIO bus.

When an XDP program is installed, tun_build_skb() grabs a reference to
the current page fragment page if the program returns XDP_REDIRECT or
XDP_TX. However, since tun_xdp_act() passes through negative return
values from the XDP program, it is possible to trigger the error path by
mistake and accidentally drop a reference to the fragments page without
taking one, leading to a spurious free. This is believed to be the cause
of some KASAN use-after-free reports from syzbot [1], although without a
reproducer it is not possible to confirm whether this patch fixes the
problem.

Ensure that we only drop a reference to the fragments page if the XDP
transmit or redirect operations actually fail.

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.

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
   - Update Amlogic audio clock gate hierarchy for meson8 and gxbb
   - Update Amlogic g12a spicc clock sources
   - Support for Ingenic X1000 TCU clks"

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"

Pull keyrings fixes from David Howells:
 "Here's a couple of patches that fix a circular dependency between
  holding key->sem and mm->mmap_sem when reading data from a key.

  One potential issue is that a filesystem looking to use a key inside,
  say, ->readpages() could deadlock if the key being read is the key
  that's required and the buffer the key is being read into is on a page
  that needs to be fetched.

  The case actually detected is a bit more involved - with a filesystem
  calling request_key() and locking the target keyring for write - which
  could be being read"
