An SError was detected when trying to print the supported pins in a
pinctrl device which supports multiple pins per register. This change
fixes the pcs_pin_dbg_show() in pinctrl-single driver when
bits_per_mux != 0. In addition move offset calculation and pin offset in
register to common function.

Remove unused parameter 'pin_pos' from pcs_add_pin().

Right now the handling order depends on how entries are coming which is
corresponding with order in DT. We have reached the case with DT overlays
where conf and mux descriptions are exchanged which ends up in sequence
that firmware has been asked to perform configuration before requesting the
pin.

The patch is enforcing the order that pin is requested all the time first
followed by pin configuration. This change will ensure that firmware gets
requests in the right order.

In case of ACPI boot, GPIO core does the right thing to parse GPIO pin
configs from ACPI table, and call into gpio_chip's .set_config hook for
setting them up.  It enables such support on qcom platform by using
generic config function, which in turn calls into .pin_config_set of
pinconf for setting up hardware.  For qcom platform, it's possible to
reuse pin group config functions for pin config hooks, because every pin
is maintained as a single group.

This change fixes the problem that Touchpad of Lenovo Flex 5G laptop
doesn't work with ACPI boot, because PullUp config of Touchpad GpioInt
pin is not set up by the kernel.

Add "pinmux-select" to debugfs which will activate a pin function for a
given pin group:

  echo "<group-name function-name>" > pinmux-select

The write operation pinmux_select() handles this by checking that the
names map to valid selectors and then calling ops->set_mux().

The existing "pinmux-functions" debugfs file lists the pin functions
registered for the pin controller. For example:

  function: pinmux-uart0, groups = [ pinmux-uart0-pins ]
  function: pinmux-mmc0, groups = [ pinmux-mmc0-pins ]
  function: pinmux-mmc1, groups = [ pinmux-mmc1-pins ]
  function: pinmux-i2c0, groups = [ pinmux-i2c0-pins ]
  function: pinmux-i2c1, groups = [ pinmux-i2c1-pins ]
  function: pinmux-spi1, groups = [ pinmux-spi1-pins ]

To activate function pinmux-i2c1 on group pinmux-i2c1-pins:

  echo "pinmux-i2c1-pins pinmux-i2c1" > pinmux-select

   - Clean up some naming that had gone stale.

   - Fix race condition around task_work rework that went into this

   - Implement unshare. Used for when the original task does unshare(2)
     or setuid/seteuid and friends, drops the original workers and forks
     new ones.

   - Drop the only remaining piece of state shuffling we had left, which
     was cred. Move it into issue instead, and we can drop all of that
     code too.

   - Kill f_op->flush() usage. That was such a nasty hack that we had
     out of necessity, we no longer need it.

   - Following from ->flush() removal, we can also drop various bits of
     ctx state related to SQPOLL and cancelations.

   - Fix an issue with IOPOLL retry, which originally was fallout from a
     filemap change (removing iov_iter_revert()), but uncovered an issue
     with iovec re-import too late.

   - Fix an issue with system suspend.

   - Use xchg() for fallback work, instead of cmpxchg().

   - Properly destroy io-wq on exec.

   - Add create_io_thread() core helper, and use that in io-wq and
     io_uring. This allows us to remove various silly completion events
     related to thread setup.

   - A few error handling fixes.

  This should be the grunt of fixes necessary for the new workers, next
  week should be quieter. We've got a pending series from Pavel on
  cancelations, and how tasks and rings are indexed. Outside of that,
