USB: add RESET_RESUME quirk for NVIDIA Jetson devices in RCM
NVIDIA Jetson devices in Force Recovery mode (RCM) do not support
suspending, ie. flashing fails if the device has been suspended. The
devices are still visible in lsusb and seem to work otherwise, making
the issue hard to debug. This has been discovered in various forum
posts, eg. [1].
The patch has been tested on NVIDIA Jetson AGX Xavier, but I'm adding
all the Jetson models listed in [2] on the assumption that they all
behave similarly.

usb: chipidea: make configs for glue drivers visible with EXPERT
Commit
6a108a14fa35 ("kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT")
introduces CONFIG_EXPERT to carry the previous intent of CONFIG_EMBEDDED
and just gives that intent a much better name. That has been clearly a good
and long overdue renaming, and it is clearly an improvement to the kernel
build configuration that has shown to help managing the kernel build
configuration in the last decade.
However, rather than bravely and radically just deleting CONFIG_EMBEDDED,
this commit gives CONFIG_EMBEDDED a new intended semantics, but keeps it
open for future contributors to implement that intended semantics:
A new CONFIG_EMBEDDED option is added that automatically selects
CONFIG_EXPERT when enabled and can be used in the future to isolate
options that should only be considered for embedded systems (RISC
architectures, SLOB, etc).
Since then, this CONFIG_EMBEDDED implicitly had two purposes:
- It can make even more options visible beyond what CONFIG_EXPERT makes
visible. In other words, it may introduce another level of enabling the
visibility of configuration options: always visible, visible with
CONFIG_EXPERT and visible with CONFIG_EMBEDDED.
- Set certain default values of some configurations differently,
following the assumption that configuring a kernel build for an
embedded system generally starts with a different set of default values
compared to kernel builds for all other kind of systems.
Considering the first purpose, at the point in time where CONFIG_EMBEDDED
was renamed to CONFIG_EXPERT, CONFIG_EXPERT already made 130 more options
become visible throughout all different menus for the kernel configuration.
Over the last decade, this has gradually increased, so that currently, with
CONFIG_EXPERT, roughly 170 more options become visible throughout all
different menus for the kernel configuration. In comparison, currently with
CONFIG_EMBEDDED enabled, just seven more options are visible, one in x86,
one in arm, and five for the ChipIdea Highspeed Dual Role Controller.
As the numbers suggest, these two levels of enabling the visibility of even
more configuration options---beyond what CONFIG_EXPERT enables---never
evolved to a good solution in the last decade. In other words, this
additional level of visibility of configuration option with CONFIG_EMBEDDED
compared to CONFIG_EXPERT has since its introduction never become really
valuable. It requires quite some investigation to actually understand what
is additionally visible and it does not differ significantly in complexity
compared to just enabling CONFIG_EXPERT. This CONFIG_EMBEDDED---or any
other config to show more detailed options beyond CONFIG_EXPERT---is
unlikely to be valuable unless somebody puts significant effort in
identifying how such visibility options can be properly split and creating
clear criteria, when some config option is visible with CONFIG_EXPERT and
when some config option is visible only with some further option enabled
beyond CONFIG_EXPERT, such as CONFIG_EMBEDDED attempted to do. For now, it
is much more reasonable to simply make those additional seven options that
visible with CONFIG_EMBEDDED, visible with CONFIG_EXPERT, and then remove
CONFIG_EMBEDDED. If anyone spends significant effort in structuring the
visibility of config options, they may re-introduce suitable new config
options simply as they see fit.
Make the configs for usb chipidea glue drivers visible when CONFIG_EXPERT
is enabled.

- A fix and a revert for some changes to use READ/WRITE_ONCE() which
caused problems with KASAN enabled due to sanitisation calls being
introduced in low-level paths that can't cope with it.
- Fix build errors on 32-bit caused by the syscall table being
misaligned sometimes.
- Two fixes to get IBM Cell native machines booting again, which had
bit-rotted while my QS22 was temporarily out of action.
- Fix the papr_scm driver to not assume the order of events returned by
the hypervisor is stable, and a related compile fix.

Makefile.extrawarn: re-enable -Wformat for clang; take 2
-Wformat was recently re-enabled for builds with clang, then quickly
re-disabled, due to concerns stemming from the frequency of default
argument promotion related warning instances.
commit
258fafcd0683 ("Makefile.extrawarn: re-enable -Wformat for clang")
commit
21f9c8a13bb2 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"")
ISO WG14 has ratified N2562 to address default argument promotion
explicitly for printf, as part of the upcoming ISO C2X standard.
The behavior of clang was changed in clang-16 to not warn for the cited
cases in all language modes.
Add a version check, so that users of clang-16 now get the full effect
of -Wformat. For older clang versions, re-enable flags under the
-Wformat group that way users still get some useful checks related to
format strings, without noisy default argument promotion warnings. I
intentionally omitted -Wformat-y2k and -Wformat-security from being
re-enabled, which are also part of -Wformat in clang-16.

mm: pagewalk: Fix race between unmap and page walker
The mmap lock protects the page walker from changes to the page tables
during the walk. However a read lock is insufficient to protect those
areas which don't have a VMA as munmap() detaches the VMAs before
downgrading to a read lock and actually tearing down PTEs/page tables.
For users of walk_page_range() the solution is to simply call pte_hole()
immediately without checking the actual page tables when a VMA is not
present. We now never call __walk_page_range() without a valid vma.
For walk_page_range_novma() the locking requirements are tightened to
require the mmap write lock to be taken, and then walking the pgd
directly with 'no_vma' set.
This in turn means that all page walkers either have a valid vma, or
it's that special 'novma' case for page table debugging. As a result,
all the odd '(!walk->vma && !walk->no_vma)' tests can be removed.

Now acpi_os_ioremap() is marked with __init because it calls memblock_
is_memory() which is also marked with __init in the !ARCH_KEEP_MEMBLOCK

as acpi_os_{read, write}_memory() and causes section mismatch warnings:
