Pull modules updates from Luis Chamberlain:
"Summary of the changes worth highlighting from most interesting to
boring below:
- Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
circumvent the protection he put in place in year 2020 to prevent
proprietary modules from using GPL only symbols, and also ensuring
proprietary modules which export symbols grandfather their taint.
That was done through year 2020 commit 262e6ae7081d ("modules:
inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
clarifing __symbol_get() was only ever intended to prevent module
reference loops by Linux kernel modules and so making it only find
symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
used by Nvidia was to use symbol_get() to purposely swift through
proprietary module symbols and completely bypass our traditional
EXPORT_SYMBOL*() annotations and community agreed upon
restrictions.
A small set of preamble patches fix up a few symbols which just
needed adjusting for this on two modules, the rtc ds1685 and the
networking enetc module. Two other modules just needed some build
fixing and removal of use of __symbol_get() as they can't ever be
modular, as was done by Arnd on the ARM pxa module and Christoph
did on the mmc au1xmmc driver.
This is a good reminder to us that symbol_get() is just a hack to
address things which should be fixed through Kconfig at build time
as was done in the later patches, and so ultimately it should just
go.
- Extremely late minor fix for old module layout 055f23b74b20
("module: check for exit sections in layout_sections() instead of
module_init_section()") by James Morse for arm64. Note that this
layout thing is old, it is *not* Song Liu's commit ac3b43283923
("module: replace module_layout with module_memory"). The issue
however is very odd to run into and so there was no hurry to get
this in fast.
- Although the fix did not go through the modules tree I'd like to
highlight the fix by Peter Zijlstra in commit 54097309620e
("x86/static_call: Fix __static_call_fixup()") now merged in your
tree which came out of what was originally suspected to be a
fallout of the the newer module layout changes by Song Liu commit
ac3b43283923 ("module: replace module_layout with module_memory")
instead of module_init_section()"). Thanks to the report by
Christian Bricart and the debugging by Song Liu & Peter that turned
to be noted as a kernel regression in place since v5.19 through
commit ee88d363d156 ("x86,static_call: Use alternative RET
encoding").
I highlight this to reflect and clarify that we haven't seen more
fallout from ac3b43283923 ("module: replace module_layout with
module_memory").
- RISC-V toolchain got mapping symbol support which prefix symbols
with "$" to help with alignment considerations for disassembly.
This is used to differentiate between incompatible instruction
encodings when disassembling. RISC-V just matches what ARM/AARCH64
did for alignment considerations and Palmer Dabbelt extended
is_mapping_symbol() to accept these symbols for RISC-V. We already
had support for this for all architectures but it also checked for
the second character, the RISC-V check Dabbelt added was just for
the "$". After a bit of testing and fallout on linux-next and based
on feedback from Masahiro Yamada it was decided to simplify the
check and treat the first char "$" as unique for all architectures,
and so we no make is_mapping_symbol() for all archs if the symbol
starts with "$".
The most relevant commit for this for RISC-V on binutils was:
https://sourceware.org/pipermail/binutils/2021-July/117350.html
- A late fix by Andrea Righi (today) to make module zstd
decompression use vmalloc() instead of kmalloc() to account for
large compressed modules. I suspect we'll see similar things for
other decompression algorithms soon.
- samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and
Chen Jiahao"

to optionally call a function from sharpsl_pm.c if that is
built. However, the two files are always built together
these days, and have been for a long time, so this can
be changed to a normal function call.

ARM exclusively uses GENERIC_IRQ_MULTI_HANDLER, so at some point
set_handle_irq() needs to be called to handle system-wide
interrupts.
For all DT-enabled boards, this call happens down in the
drivers/irqchip subsystem, after locating the target irqchip
driver from the device tree.
We still have a few instances of the boardfiles with machine
descriptors passing a machine-specific .handle_irq() to the
ARM kernel core.
Get rid of this by letting the few remaining machines consistently
call set_handle_irq() from the end of the .init_irq() callback
instead and diet down one member from the machine descriptor.

Making virt_to_pfn() a static inline taking a strongly typed
(const void *) makes the contract of a passing a pointer of that
type to the function explicit and exposes any misuse of the
macro virt_to_pfn() acting polymorphic and accepting many types
such as (void *), (unitptr_t) or (unsigned long) as arguments
without warnings.
Doing this is a bit intrusive: virt_to_pfn() requires
PHYS_PFN_OFFSET and PAGE_SHIFT to be defined, and this is defined in
<asm/page.h>, so this must be included *before* <asm/memory.h>.
The use of macros were obscuring the unclear inclusion order here,
as the macros would eventually be resolved, but a static inline
like this cannot be compiled with unresolved macros.
The naive solution to include <asm/page.h> at the top of
<asm/memory.h> does not work, because <asm/memory.h> sometimes
includes <asm/page.h> at the end of itself, which would create a
confusing inclusion loop. So instead, take the approach to always
unconditionally include <asm/page.h> at the end of <asm/memory.h>
arch/arm uses <asm/memory.h> explicitly in a lot of places,
however it turns out that if we just unconditionally include
<asm/memory.h> into <asm/page.h> and switch all inclusions of
<asm/memory.h> to <asm/page.h> instead, we enforce the right
order and <asm/memory.h> will always have access to the
definitions.
Put an inclusion guard in place making it impossible to include
<asm/memory.h> explicitly.

The Nokia 770 is using GPIOs from the global numberspace on the
CBUS node to pass down to the LCD controller. This regresses when we
let the OMAP GPIO driver use dynamic GPIO base.
The Nokia 770 now has dynamic allocation of IRQ numbers, so this
needs to be fixed for it to work.
As this is the only user of LCD MIPID we can easily augment the
driver to use a GPIO descriptor instead and resolve the issue.
The platform data .shutdown() callback wasn't even used in the
code, but we encode a shutdown asserting RESET in the remove()
callback for completeness sake.
The CBUS also has the ADS7846 touchscreen attached.
Populate the devices on the Nokia 770 CBUS I2C using software
nodes instead of platform data quirks. This includes the LCD
and the ADS7846 touchscreen so the conversion just brings the LCD
along with it as software nodes is an all-or-nothing design
pattern.
The ADS7846 has some limited support for using GPIO descriptors,
let's convert it over completely to using device properties and then
fix all remaining boardfile users to provide all platform data using
software nodes.
Dump the of includes and of_match_ptr() in the ADS7846 driver as part
of the job.
Since we have to move ADS7846 over to obtaining the GPIOs it is
using exclusively from descriptors, we provide descriptor tables
for the two remaining in-kernel boardfiles using ADS7846:
- PXA Spitz
- MIPS Alchemy DB1000 development board
It was too hard for me to include software node conversion of
these two remaining users at this time: the spitz is using a
hscync callback in the platform data that would require further
GPIO descriptor conversion of the Spitz, and moving the hsync
callback down into the driver: it will just become too big of
a job, but it can be done separately.
The MIPS Alchemy DB1000 is simply something I cannot test, so take
the easier approach of just providing some GPIO descriptors in
this case as I don't want the patch to grow too intrusive.
As we see that several device trees have incorrect polarity flags
and just expect to bypass the gpiolib polarity handling, fix up
all device trees too, in a separate patch.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

There is currently no devicetree support for pxa930 or pxa935
SoCs, and no board files remain. As it seems unlikely that anyone
is going to add DT support soon, let's drop the SoC specific code

The majority of all pxa board files has not been touched in a long time,
and no users have spoken up in favor of keeping them around. This leaves
only support for the platforms that were already converted to DT, as
well as the gumstix and spitz/akita/borzoi machines that work in qemu
and can still be converted to DT later.

After commit b5aaaa666a85 ("ARM: pxa: add Kconfig dependencies for
ATAGS based boards"), the default PXA build no longer includes support
for the board files that are considered unused.
As a side-effect of this, the PXA310 and PXA320 support is not built
into the kernel any more, even though it should work in principle as
long as the symbols are enabled. As Robert points out, there are dts
files for zylonite and cm-x300, though those have not made it into the
mainline kernel.

Pull ARM boardfile deprecation from Arnd Bergmann:
"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"

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.

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.

PXA and StrongARM1100 traditionally map their I/O space 1:1 into virtual
memory, using a per-bus io_offset that matches the base address of the
ioremap mapping.
In order for PXA to work in a multiplatform config, this needs to
change so I/O space starts at PCI_IOBASE (0xfee00000). Since the pcmcia
soc_common support is shared with StrongARM1100, both have to change at
the same time. The affected machines are:
- Anything with a PCMCIA slot now uses pci_remap_iospace, which
is made available to PCMCIA configurations as well, rather than
just PCI. The first PCMCIA slot now starts at port number 0x10000.
- The Zeus and Viper platforms have PC/104-style ISA buses,
which have a static mapping for both I/O and memory space at
0xf1000000, which can no longer work. It does not appear to have
any in-tree users, so moving it to port number 0 makes them
behave like a traditional PC.
- SA1100 does support ISA slots in theory, but all machines that
originally enabled this appear to have been removed from the tree
ages ago, and the I/O space is never mapped anywhere.
- The Nanoengine machine has support for PCI slots, but looks
like this never included I/O space, the resources only define the
location for memory and config space.
With this, the definitions of __io() and IO_SPACE_LIMIT can be simplified,
as the only remaining cases are the generic PCI_IOBASE and the custom
inb()/outb() macros on RiscPC. S3C24xx still has a custom inb()/outb()
in this here, but this is already removed in another branch.

Using MTD-XIP does not work on multiplatform kernels because
it requires SoC specific register accesses to be done from
low-level flash handling functions in RAM while the rest of the
kernel sits in flash.

so remove it from PXA to avoid spending a lot of time on

To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting

Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
