Pull sh updates from John Paul Adrian Glaubitz:
 "This is a bit larger than my previous one and mainly consists of
  clean-up work in the arch/sh directory by Geert Uytterhoeven and Randy
  Dunlap.

  Additionally, this fixes a bug in the Storage Queue code that was
  discovered while I was reviewing a patch to switch the code to the
  bitmap API by Christophe Jaillet.

  So this contains both a fix for the original bug in the Storage Queue
  code that can be backported later as well as the Christophe's patch to
  swich the code to the bitmap API.

  Summary:

   - Use generic GCC library routines

   - sq: Use the bitmap API when applicable

   - sq: Fix incorrect element size for allocating bitmap buffer

   - pci: Remove unused variable in SH-7786 PCI Express code

   - mcount.S: fix build error when PRINTK is not enabled

   - remove sh5/sh64 last fragments

   - math-emu: fix macro redefined warning

   - init: use OF_EARLY_FLATTREE for early init

   - nmi_debug: fix return value of __setup handler

   - SH2007: drop the bad URL info"

Pull driver core updates from Greg KH:
 "Here is the large set of driver core changes for 6.4-rc1.

  Once again, a busy development cycle, with lots of changes happening
  in the driver core in the quest to be able to move "struct bus" and
  "struct class" into read-only memory, a task now complete with these
  changes.

  This will make the future rust interactions with the driver core more
  "provably correct" as well as providing more obvious lifetime rules
  for all busses and classes in the kernel.

  The changes required for this did touch many individual classes and
  busses as many callbacks were changed to take const * parameters
  instead. All of these changes have been submitted to the various
  subsystem maintainers, giving them plenty of time to review, and most
  of them actually did so.

  Other than those changes, included in here are a small set of other
  things:

   - kobject logging improvements

   - cacheinfo improvements and updates

   - obligatory fw_devlink updates and fixes

   - documentation updates

   - device property cleanups and const * changes

   - firwmare loader dependency fixes.

  All of these have been in linux-next for a while with no reported
  problems"

Instead of open-coding it everywhere introduce a tiny helper that can be
used to iterate over each resource of a PCI device, and convert the most
obvious users into it.

While at it drop doubled empty line before pdev_sort_resources().

No functional changes intended.

Direct access to the struct bus_type dev_root pointer is going away soon
so replace that with a call to bus_get_dev_root() instead, which is what
it is there for.

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);

            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);

Add these PCI class codes to pci_ids.h:

  PCI_CLASS_BRIDGE_PCI_SUBTRACTIVE

Use these defines in all kernel code for describing PCI class codes for
normal and subtractive PCI bridges.

When G2_DMA is enabled and SH_DMA is disabled, it results in the following
Kbuild warning:

WARNING: unmet direct dependencies detected for SH_DMA_API
  Depends on [n]: SH_DMA [=n]
  Selected by [y]:
  - G2_DMA [=y] && SH_DREAMCAST [=y]

The reason is that G2_DMA selects SH_DMA_API without depending on or
selecting SH_DMA while SH_DMA_API depends on SH_DMA.

When G2_DMA was first introduced with commit 40f49e7ed77f
("sh: dma: Make G2 DMA configurable."), this wasn't an issue since
SH_DMA_API didn't have such dependency, and this way was the only way to
enable it since SH_DMA_API was non-visible. However, later SH_DMA_API was
made visible and dependent on SH_DMA with commit d8902adcc1a9
("dmaengine: sh: Add Support SuperH DMA Engine driver").

Let G2_DMA depend on SH_DMA_API instead to avoid Kbuild issues.
