7d9d077c78 RCU pull request for v5.20 (or whatever)
This pull request contains the following branches:
 
 doc.2022.06.21a: Documentation updates.
 
 fixes.2022.07.19a: Miscellaneous fixes.
 
 nocb.2022.07.19a: Callback-offload updates, perhaps most notably a new
 	RCU_NOCB_CPU_DEFAULT_ALL Kconfig option that causes all CPUs to
 	be offloaded at boot time, regardless of kernel boot parameters.
 	This is useful to battery-powered systems such as ChromeOS
 	and Android.  In addition, a new RCU_NOCB_CPU_CB_BOOST kernel
 	boot parameter prevents offloaded callbacks from interfering
 	with real-time workloads and with energy-efficiency mechanisms.
 
 poll.2022.07.21a: Polled grace-period updates, perhaps most notably
 	making these APIs account for both normal and expedited grace
 	periods.
 
 rcu-tasks.2022.06.21a: Tasks RCU updates, perhaps most notably reducing
 	the CPU overhead of RCU tasks trace grace periods by more than
 	a factor of two on a system with 15,000 tasks.	The reduction
 	is expected to increase with the number of tasks, so it seems
 	reasonable to hypothesize that a system with 150,000 tasks might
 	see a 20-fold reduction in CPU overhead.
 
 torture.2022.06.21a: Torture-test updates.
 
 ctxt.2022.07.05a: Updates that merge RCU's dyntick-idle tracking into
 	context tracking, thus reducing the overhead of transitioning to
 	kernel mode from either idle or nohz_full userspace execution
 	for kernels that track context independently of RCU.  This is
 	expected to be helpful primarily for kernels built with
 	CONFIG_NO_HZ_FULL=y.

Pull random number generator updates from Jason Donenfeld:
 "Though there's been a decent amount of RNG-related development during
  this last cycle, not all of it is coming through this tree, as this
  cycle saw a shift toward tackling early boot time seeding issues,
  which took place in other trees as well.

  Here's a summary of the various patches:

   - The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot
     option have been removed, as they overlapped with the more widely
     supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and
     "random.trust_cpu". This change allowed simplifying a bit of arch
     code.

   - x86's RDRAND boot time test has been made a bit more robust, with
     RDRAND disabled if it's clearly producing bogus results. This would
     be a tip.git commit, technically, but I took it through random.git
     to avoid a large merge conflict.

   - The RNG has long since mixed in a timestamp very early in boot, on
     the premise that a computer that does the same things, but does so
     starting at different points in wall time, could be made to still
     produce a different RNG state. Unfortunately, the clock isn't set
     early in boot on all systems, so now we mix in that timestamp when
     the time is actually set.

   - User Mode Linux now uses the host OS's getrandom() syscall to
     generate a bootloader RNG seed and later on treats getrandom() as
     the platform's RDRAND-like faculty.

   - The arch_get_random_{seed_,}_long() family of functions is now
     arch_get_random_{seed_,}_longs(), which enables certain platforms,
     such as s390, to exploit considerable performance advantages from
     requesting multiple CPU random numbers at once, while at the same
     time compiling down to the same code as before on platforms like
     x86.

   - A small cleanup changing a cmpxchg() into a try_cmpxchg(), from
     Uros.

   - A comment spelling fix"

architecture trees in the full commentary in the pull request:

7d0d3fa733 ARM: boardfile deprecation for 6.0
Over the past ten years, new machine support was based on device tree,
 and an initial set of about 400 boards using ATAGS with boardfile
 for booting were grandfathered in, with about half of them either
 removed or converted to DT over time.
 
 Based on the recent mailing list discussion I started, I have now
 turned the findings into a set of patches that marks most board files as
 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
 
 For the boards that are marked as unused, there are two final chances
 for potential users: The removal is scheduled to take place after the
 longterm stable kernel at the end of 2022, so users can stay on that
 version for another few years, and if anyone still has one of these
 machines and is planning to keep updating kernels beyond that version,
 they can speak up now to have their boards taken off the list again.
 
 Waiting for the LTS release also makes sure that there will be at
 least one longterm kernel that contains the recent multiplatform
 conversion along while still supporting all legacy boards.
 
 The short summary of the current status is:
 
  - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
    users and will be removed entirely.
 
  - The mmp and davinci platforms have DT support for the important
    machines and will become DT-only after this.
 
  - s3c64xx, dove, orion5x, and pxa keep some board files to allow
    those to be migrated over to DT more easily, but most board files
    are getting removed now. DT support on these platforms is partially
    working but requires changes to additional drivers for the other
    boards.
 
  - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at
    the moment but have some boards with known users. Removing the board
    files that nobody uses should make it easier to try a DT conversion
    if anyone cares.
 
 There is no explicit timeline what happens with the boards that remain
 after this removal, but I expect to revisit this in the future, and
 with most boards gone, there will be a good time to do a treewide
 review of platform drivers that never gained DT support and have no
 remaining in-tree board files.

3a829d267e ARM: SoC defconfig updates for 6.0
This branch includes the usual updates to defconfig files, enabling
 additional driver support for the supported platforms.
 
 There is also a global refresh for all of them that reorders the
 lines according to the 'savedefconfig' output, but without removing
 lines that are no longer part of the refresh.
 
 I went through the most common removed lines to also address them
 while making sure to catch renamed options and add them back
 under the new name.
 
 The boardfile deprecation branch is based on top of this to avoid
 conflicts against removing the unused boardfile configs from the
 generic defconfig files.

3976d758e0 ARM: DT changes for 6.0
As usual, the bulk of the changes for the SoC tree are devicetree file
 updates, and most of these changes are for 64-bit embedded machines.
 As before, there are a ton of style cleanups, and additional hardware
 support for existing machines.
 
 Looking only at the new SoC, the notable additions are:
 
  - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
    BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
    BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
    Each SoC comes with a corresponding reference board.
 
  - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
    i.MX8 embedded SoCs, now using Cortex-A55 cores and the
    Ethos-U65 NPU.
 
  - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
    of Arm based Laptop SoCs, and its automotive cousin, the
    SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
    laptop that also gets added here in addition to the reference
    boards.
 
  - Allwinner H616, a newer version of the H6 SoC, targeted at
    Set-top-box applications. It comes with dts files for the
    Orange Pi zero2 single-board computer and the X96 Mate
    set-top-box
 
  - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
    in the Armada SoC family based on the Cortex-A55 core.
 
 New machines based on previously supported SoCs include:
 
  - Several new machines on NXP i.MX platforms: multiple Toradex
    Colibri boards using the "Iris" and "Ixora" carriers,
    DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
    TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
 
  - Google Chameleon v3 FPGA board based on Intel Arria10 and
    Stratix 10 Software Virtual platform, both in the SoCFPGA
    platform.
 
  - Two new wireless devices based on Broadcom SoCs:
    The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
 
  - Improved Chromebook support for both the Mediatek and Qualcomm
    SoC families brought added machines: Acer Chromebook 514 (MT8192),
    Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
    machines including the Lenovo IdeaPad Chromebook Duet 3.
 
  - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
    Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
 
  - Finally, there are a few development board on other chips:
    PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
    DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm
    SDM660)

ec85bd369f ARM: findbit: fix overflowing offset
When offset is larger than the size of the bit array, we should not
attempt to access the array as we can perform an access beyond the
end of the array. Fix this by changing the pre-condition.

Using "cmp r2, r1; bhs ..." covers us for the size == 0 case, since
this will always take the branch when r1 is zero, irrespective of
the value of r2. This means we can fix this bug without adding any
additional code!

fb0fd3469e ARM: 9216/1: Fix MAX_DMA_ADDRESS overflow
Commit 26f09e9b3a06 ("mm/memblock: add memblock memory allocation apis")
added a check to determine whether arm_dma_zone_size is exceeding the
amount of kernel virtual address space available between the upper 4GB
virtual address limit and PAGE_OFFSET in order to provide a suitable
definition of MAX_DMA_ADDRESS that should fit within the 32-bit virtual
address space. The quantity used for comparison was off by a missing
trailing 0, leading to MAX_DMA_ADDRESS to be overflowing a 32-bit
quantity.

This was caught thanks to CONFIG_DEBUG_VIRTUAL on the bcm2711 platform
where we define a dma_zone_size of 1GB and we have a PAGE_OFFSET value
of 0xc000_0000 (CONFIG_VMSPLIT_3G) leading to MAX_DMA_ADDRESS being
0x1_0000_0000 which overflows the unsigned long type used throughout
__pa() and then __virt_addr_valid(). Because the virtual address passed
to __virt_addr_valid() would now be 0, the function would loudly warn
and flood the kernel log, thus making the platform unable to boot
properly.

Let's make timer-ti-dm selectable for ARCH_K3, and add a separate option

For older TI SoCs, we are already selecting OMAP_DM_TIMER in
arch/arm/mach-omap*/Kconfig. For mach-omap2, we need to now also select
OMAP_DM_SYSTIMER.

ARM: pxa2xx: Fix GPIO descriptor tables
Laurence reports:

"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:

sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!

Looking at the recent changes, I found that commit 31455bbda208 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."

After reviewing the change I conclude that the same fix is needed
for all affected boards.

1785ab7698 ARM: cns3xxx: add CONFIG_UNUSED_BOARD_FILES dependency
Krzysztof Halasa has kept the cns3xxx platform working for a long time
but has moved away from working on it. The OpenWRT port was dropped in
2020, and support for the Gateworks Laguna platform never made it into
the mainline kernel, which only supports the reference design.

Further, the ARM11MPCore has an unresolved issue with instruction cache
coherency, and removing support for the remaining platforms using this
core would be the easiest solution.

Mark the entire platform as unused now, to be removed in early 2023 if
no users show up.

Most of the s3c64xx board files appear to be unused, as the better

the Wolfson Cragganmore board, which remains in use as the reference
design for Wolfson/Cirrus devices. As the other boards get removed,
this one stays around along with the DT based machines.

The s3c6400_defconfig file now disables the unused boards, while the
s3c24xx defconfig files all turn on CONFIG_UNUSED_BOARD_FILES to
remain usable.

Legacy board files with no known users are planned to get removed in

According to Tony, the actual users are all on OSK, Nokia770, and
AMS-Delta. Additionally, the sx1 and palmte boards are supported by qemu,
which is convenient for testing, so all five stay around past the initial
board removal.

As omap1 is now part of the multiplatform build and uses the common-clk
framework, it has become easier to convert these to use devicetree
based booting in the future.

0c00a537bc ARM: orion: add ATAGS dependencies
Most of the remaining arm board files in the kernel are unused and will be
removed in early 2023 if no users step up.  So far I got no user replies
about the orion5x and mv78xx0 machines, but these are still supported
in the default kernel of the Debian 'armel' (armv5 softfloat) distro,
and there is an active project on github that tries to keep some of
these machines working, and Mauri Sandberg is working on a DT conversion
for the D-Link DNS-323.

It appears the Debian-on-Buffalo project has not got the Terastation WXL
working in a few years, and the other mv78xx0 machines are just the
reference designs, so I assume none of these have remaining users.

For the Orion5x family, the same is probably true for its reference
implementations (RD88Fxxxxx, DB88F281) and the machines with less than
64MB of memory (WNR854T, WRT350N v2).

The remaining nine machines are now scheduled to be kept for at least
2023, hopefully to be replaced with DT based versions.

The mv78xx0_defconfig file needs to enable CONFIG_UNUSED_BOARD_FILES
to still build, while the other affected defconfig files lose the
specific boards.

b5aaaa666a ARM: pxa: add Kconfig dependencies for ATAGS based boards
Most of the traditional board files are no longer used by anyone and
will be removed next year, while the DT based machine support remains.

Adding a CONFIG_ATAGS dependency around all the board files means
that they now actaully get disabled when ATAGS support is left out,
and the individual boards that have no known users are marked
as depending on CONFIG_UNUSED_BOARD_FILES, with the plan to remove
them in early 2023 unless someone else shows interest.

Laurence de Bruxelles intends to work on converting the Spitz/Akita/Borzoi
family of Sharp Zaurus SL machines to DT, to make that easier those
remain for the moment.

In addition, the "Gumstix" machine is the one that is supported in
qemu with 256MB of RAM, which makes it particularly nice for testing,
I'm leaving it in hoping that someone can take care of converting it to
DT as well.

Finally, Marc Zyngier is still able to test the Zeus and Viper machines,
so these could be saved as well if anyone wants to conver them to DT.
This seems less likely, so I'm marking them as unused for the time being.

For the defconfig files, both the pxa3xx_defconfig and pxa_defconfig
now only enable the boards that are not marked as unused, while all the
other ones explicitly enable CONFIG_UNUSED_BOARD_FILES to still allow
building the kernels.

acb926d618 ARM: add CONFIG_UNUSED_BOARD_FILES
Based on the recent mailing list discussion, most board file support
has no remaining users and can be scheduled for removal early next
year.

If a board is still found to have users, it will remain for this round
but users are encouraged to migrate to devicetree based booting where
possible.

The timing is meant to ensure the next longterm supported kernel
still contains all the board files, giving another year of support
for potential users that did not speak up and would otherwise be
stuck on the v5.15.y longterm kernel from 2021.

96a4ce30c2 ARM: add ATAGS dependencies to non-DT platforms
There are a total of eight platforms that only suppor ATAGS based boot
with board files but no devicetree booting.

For dove, the DT support is part of the mvebu platform, which shares
driver but no code in arch/arm.

Most of these will never get converted to DT, and the majority of the
board files appear to be entirely unused already. There are still known
users on a few machines, and there may be interest in converting some
omap1, ep93xx or footbridge machines over in the future.

For the moment, just add a Kconfig dependency to hide these platforms
completely when CONFIG_ATAGS is disabled, and reorder the priority
of the options: Rather than offering to turn ATAGS off for platforms
that have DT support, make it a top-level setting that determines
which platforms are visible.

The s3c24xx platform supports one machine with DT support, but it
cannot be built without also including ATAGS support, and the
entire platform is scheduled for removal, so leaving the entire
platform behind a dependency seems good enough.

All defconfig files should keep working, as the option remains default
enabled.

fa8bbb13ab49 ("ARM: use new LEDS CPU trigger stub to replace old one"),
but some defconfig files still reference it.

Replace it and its sub-options with the corresponding new versions.

Some of these machines may not actually have a new-style LED driver,
and I did not check them individually as most of the machines are
going away soon anyway.

5746240f21 ARM: defconfig: remove broken CONFIG_THUMB disables
Since commit 1515b186c235 ("ARM: make configuration of userspace
Thumb support an expert option"), CONFIG_THUMB cannot be disabled
unless one turns on CONFIG_EXPERT first.

This is probably for the better, so remove the statements that
turn it off.

ddd366bf01 ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y
CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

Fixes: f9b3cd245784 ("Kconfig.debug: make DEBUG_INFO selectable from a choice")

186d24bff2 ARM: defconfig: remove stale CONFIG_ZBOOT_ROM entries
The default is always 0x0 after commit 39c3e304567a ("ARM: 8984/1:
Kconfig: set default ZBOOT_ROM_TEXT/BSS value to 0x0"), so any
defconfig file that has these two lines can now drop them to reduce
the diff against the 'make savedefconfig' version.

2002f39687 ARM: refresh defconfig files
A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.

I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

99978d2fd9 More Qualcomm driver changes for v5.20
This adds support for booting secondary cores, SPM, SMD-RPM and RPM
 power-domain support for the MSM8909 platform.
 
 It drops an unnecessary print in icc-bwmon, corrects SA8540P entries in
 socinfo and a Kconfig build dependency for QCOM_RPMPD.
 
 Lastly it continues to clean up up the Devicetree bindings for the
 Qualcomm drivers.
