  function is also transitioned to use dev_err_probe() to provide better

Pull clk updates from Stephen Boyd:
 "There's one large change in the core clk framework here. We change how
  clk_set_rate_range() works so that the frequency is re-evaulated each
  time the rate is changed. Previously we wouldn't let clk providers see
  a rate that was different if it was still within the range, which
  could be bad for power if the clk could run slower when a range
  expands. Now the clk provider can decide to do something differently
  when the constraints change. This broke Nvidia's clk driver so we had
  to wait for the fix for that to bake a little more in -next.

  The rate range patch series also introduced a kunit suite for the clk
  framework that we're going to extend in the next release. It already
  made it easy to find corner cases in the rate range patches so I'm
  excited to see it cover more clk code and increase our confidence in
  core framework patches in the future. I also added a kunit test for
  the basic clk gate code and that work will continue to cover more
  basic clk types: muxes, dividers, etc.

  Beyond the core code we have the usual set of clk driver updates and
  additions. Qualcomm again dominates the diffstat here with lots more
  SoCs being supported and i.MX follows afer that with a similar number
  of SoCs gaining clk drivers. Beyond those large additions there's
  drivers being modernized to use clk_parent_data so we can move away
  from global string names for all the clks in an SoC. Finally there's
  lots of little fixes all over the clk drivers for typos, warnings, and
  missing clks that aren't critical and get batched up waiting for the
  next merge window to open. Nothing super big stands out in the driver
  pile. Full details are below.

  Core:
   - Make clk_set_rate_range() re-evaluate the limits each time
   - Introduce various clk_set_rate_range() tests
   - Add clk_drop_range() to drop a previously set range

Jason Donenfeld reports that my commit 1c24a186 ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.

Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.

But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero.  Which most
definitely isn't what we want either.

The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler.  Duh.  It certainly made _me_ look simple.

This has always been the rule: fdtables have several bitmaps in them,
and as a result they have to be sized properly for bitmaps.  We walk
those bitmaps in chunks of 'unsigned long' in serveral cases, but even
when we don't, we use the regular kernel bitops that are defined to work
on arrays of 'unsigned long', not on some byte array.

Now, the distinction between arrays of bytes and 'unsigned long'
normally only really ends up being noticeable on big-endian systems, but
Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
could be called with an argument that wasn't even a multiple of
BITS_PER_BYTE.  And then it fails to do the proper copy even on
little-endian machines.

The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
didn't actually sanitize the fdtable size sufficiently, and never made
sure it had the proper BITS_PER_LONG alignment.

That's partly because the alignment historically came not from having to
explicitly align things, but simply from previous fdtable sizes, and
from count_open_files(), which counts the file descriptors by walking
them one 'unsigned long' word at a time and thus naturally ends up doing
sizing in the proper 'chunks of unsigned long'.

But with the introduction of close_range(), we now have an external
source of "this is how many files we want to have", and so
sane_fdtable_size() needs to do a better job.

This also adds that explicit alignment to alloc_fdtable(), although
there it is mainly just for documentation at a source code level.  The
arithmetic we do there to pick a reasonable fdtable size already aligns
the result sufficiently.

In fact,clang notices that the added ALIGN() in that function doesn't
actually do anything, and does not generate any extra code for it.

It turns out that gcc ends up confusing itself by combining a previous
constant-sized shift operation with the variable-sized shift operations
in roundup_pow_of_two().  And probably due to that doesn't notice that
the ALIGN() is a no-op.  But that's a (tiny) gcc misfeature that doesn't
matter.  Having the explicit alignment makes sense, and would actually
matter on a 128-bit architecture if we ever go there.

This also adds big comments above both functions about how fdtable sizes
have to have that BITS_PER_LONG alignment.

This change fixes the following:

1) The flags variable is not initialized. Always use raw_spin_lock_irqsave
and raw_spin_unlock_irqrestore to serialize patching.

2) flush_kernel_vmap_range is primarily intended for DMA flushes. Since
__patch_text_multiple is often called with interrupts disabled, it is
better to directly call flush_kernel_dcache_range_asm and
flush_kernel_icache_range_asm. This avoids an extra call.

3) The final call to flush_icache_range is unnecessary.

When CPU hotplugging is enabled, the user may want to remove the
current CPU which is providing the timer ticks. If this happens
we need to find a new timesync master.

Move the common_stext function into the non-init text section if hotplug
is enabled. This function is called from the firmware when hotplugged
CPUs are brought up.

Let the PDC firmware put the CPU into firmware idle loop with the
pdc_cpu_rendezvous() function.
Signed-off-by: Helge Deller <deller@gmx.de>

Add relevant code to __cpu_die() and __cpu_disable() to finally enable
the CPU hotplugging features. Reset the irq count values in smp_callin()
to zero before bringing up the CPU.

It seems that the firmware may need up to 8 seconds to fully stop a CPU
in which no other PDC calls are allowed to be made. Use a timeout
__cpu_die() to accommodate for this.

Use "chcpu -d 1" to bring CPU1 down, and "chcpu -e 1" to bring it up.

Add pdc_cpu_rendezvous_lock() and pdc_cpu_rendezvous_unlock()
to lock PDC while CPU is transitioning into rendezvous state.
This is needed, because the transition phase may take up to 8 seconds.

Add pdc_pat_get_PDC_entrypoint() to get PDC entry point for current CPU.

If CONFIG_HOTPLUG_CPU is enabled, those functions will be run again
after bootup. So they need to reside in the .text section.

Switch away from the own cpu topology code to common code which is used
by ARM64 and RISCV. That will allow us to enable CPU hotplug later on.
Signed-off-by: Helge Deller <deller@gmx.de>

Call set_firmware_width() only once at runtime.
This prevents that hotplugged CPUs will get stuck in spinlocks later on.

The cpu_set_affinity_irq() isn't needed. Not the CPU irqs need to
change, but the slave irq chips simply need to be reprogrammed to
a new CPU irq with the txn_* functions.
Signed-off-by: Helge Deller <deller@gmx.de>

Add the missing logic to allow Lasi, WAX and Dino to set the
CPU affinity. This fixes IRQ migration to other CPUs when a
CPU is shutdown which currently holds the IRQs for one of those
chips.

Pull device properties code update from Rafael Wysocki:
 "This is based on new i2c material for 5.18-rc1 and simply reorganizes
  the code on top of it so as to group similar functions together (Andy
  Shevchenko)"

  Points) library and the power management documentation.

  Specifics:

   - Add per core DVFS support for QCom SoC (Bjorn Andersson), convert
     to yaml binding (Manivannan Sadhasivam) and various other fixes to
     the QCom drivers (Luca Weiss).

   - Add OPP table for imx7s SoC (Denys Drozdov) and minor fixes (Stefan
     Agner).

   - Fix CPPC driver's freq/performance conversions (Pierre Gondois).

   - Minor generic cleanups (Yury Norov).

   - Introduce opp-microwatt property to the OPP core, bindings, etc
     (Lukasz Luba).

   - Convert DT bindings to schema format and various related fixes
     (Yassine Oudjana).
