These options have moved around when generating the defconfig. Update
them to reduce noise when generating future changes.
The exceptions are:
- NEW_LEDS and LEDS_TRIGGERS which should drop out as they are selected
by SND_CTL_LED. Instead we will improve the logic so SND_CTL_LED
doesn't force-enable the subsystem.
- The SPI_AX88796C network device. This was enabled in v5.11 for Exynos
boards. The driver is not yet merged but there's work being done, so
leave it alone for now.
- PTP_1588_CLOCK is implied by enabled drivers STMMAC_ETH, IGB, E1000E
and FEC, but this may be changed in the future as imply does not do
what it was originally intended to do.

A number of options in the defconfig are enabled by other options;
either through selects or defaults.
SECCOMP is on by default as of commit 282a181b1a ("seccomp: Move config
option SECCOMP to arch/Kconfig").
NET_SWITCHDEV is enabled by NET_DSA. I think this is a result of commit
227d72063f ("dsa: simplify Kconfig symbols and dependencies").
SIMPLE_PM_BUS is selected ARCH_OMAP2PLUS as of commit 2a39af3870 ("ARM:
OMAP2+: Fix booting for am335x after moving to simple-pm-bus").
MICREL_PHY is selected by the ks8851 ethernet driver as of f0791b92d2 ("net:
ks8851: Select PHYLIB and MICREL_PHY in Kconfig").
SMSC_PHY is selected by USB_NET_SMSC95XX as of commit 05b35e7eb9 ("smsc95xx:
add phylib support").
STMPE_I2C is default y. It was explicitly added to the defconfig in commit
d8f0ddc838 ("ARM: defconfig: add STMPE ADC driver for P4 Note") but it's not
required.
CLK_ACTIONS and CLK_OWL_S500 was explicitly added in commit 26ba4a474a ("ARM:
multi_v7_defconfig: Enable Actions Semi platform and drivers"), but it defaults
on when ARCH_ACTIONS is enabled. Drop them.
CROS_EC_CHARDEV defaults to MFD_CROS_EC_DEV, which defaults to CROS_EC since
commit 2fa2b980e3 ("mfd / platform: cros_ec: Rename config to a better name").
TEGRA20_APB_DMA is selected by SOC_TEGRA_FUSE if ARCH_TEGRA_2x_SOC since commit
19d41e5e9c ("soc/tegra: fuse: Add APB DMA dependency for Tegra20").
USB_CHIPIDEA_TEGRA is enabled when USB_CHIPIDEA is enabled. It falls out
of the defconfig but is enabled, as intended by d50229cee6 ("ARM:
multi_v7_defconfig: Stop using deprecated USB_EHCI_TEGRA").
SERIAL_OWL_CONSOLE defaults to on when SERIAL_OWL=y, and has since it
was introduced.
Commit c6774ee035 ("media: Kconfig: make filtering devices optional")
made MEDIA_PLATFORM_SUPPORT, MEDIA_CAMERA_SUPPORT and MEDIA_CEC_SUPPORT
default y if MEDIA_SUPPORT_FILTER is disabled, so they fall out of the
defconfig.
MEDIA_CONTROLLER is selected by a number of drivers in the config, and
additionally defaults to MEDIA_PLATFORM_SUPPORT which is enabled.

- The Cirrus Logic EP93xx platform loses support for the old

The MaverickCrunch support for ep93xx never made it into glibc and
was removed from gcc in its 4.8 release in 2012. It is now one of
the last parts of arch/arm/ that fails to build with the clang
integrated assembler, which is unlikely to ever want to support it.
The two alternatives are to force the use of binutils/gas when
building the crunch support, or to remove it entirely.
According to Hartley Sweeten:
"Martin Guy did a lot of work trying to get the maverick crunch working
but I was never able to successfully use it for anything. It "kind"
of works but depending on the EP93xx silicon revision there are still
a number of hardware bugs that either give imprecise or garbage results.
I have no problem with removing the kernel support for the maverick
crunch."
Unless someone else comes up with a good reason to keep it around,
remove it now. This touches mostly the ep93xx platform, but removes
a bit of code from ARM common ptrace and signal frame handling as well.
If there are remaining users of MaverickCrunch, they can use LTS
kernels for at least another five years before kernel support ends.

The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has
been a "regression source" a lot of times. The last case is breakage of
USB mass storage boot has been commit e590474768 ("driver core: Set
fw_devlink=on by default") for multi_v7_defconfig. As long as
NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing
endlessly and prevent booting from USB mass storage device. So make
the driver built-in as in bcm2835_defconfig and arm64/defconfig.

The platform lost the framebuffer due to a commit solving a
circular dependency in v5.14-rc1, so add it back in by explicitly
selecting the framebuffer.
The U8500 has also gained a few systems using touchscreens from
Cypress, Melfas and Zinitix so add these at the same time as
we're updating the defconfig anyway.

Commit f611b1e762 ("drm: Avoid circular dependencies for CONFIG_FB")
changed the Kconfig dependencies, so COFNIG_FB is no longer selected in
defconfigs. Restore support for it in exynos_defconfig, because most
Exynos platforms had graphical console running on framebuffer device
emulated on the Exynos DRM drivers.

Patch series "drivers/char: remove /dev/kmem for good".
Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and
memory ballooning, I started questioning the existence of /dev/kmem.
Comparing it with the /proc/kcore implementation, it does not seem to be
able to deal with things like
a) Pages unmapped from the direct mapping (e.g., to be used by secretmem)
-> kern_addr_valid(). virt_addr_valid() is not sufficient.
b) Special cases like gart aperture memory that is not to be touched
-> mem_pfn_is_ram()
Unless I am missing something, it's at least broken in some cases and might
fault/crash the machine.
Looks like its existence has been questioned before in 2005 and 2010 [1],
after ~11 additional years, it might make sense to revive the discussion.
CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by
mistake?). All distributions disable it: in Ubuntu it has been disabled
for more than 10 years, in Debian since 2.6.31, in Fedora at least
starting with FC3, in RHEL starting with RHEL4, in SUSE starting from
15sp2, and OpenSUSE has it disabled as well.
1) /dev/kmem was popular for rootkits [2] before it got disabled
basically everywhere. Ubuntu documents [3] "There is no modern user of
/dev/kmem any more beyond attackers using it to load kernel rootkits.".
RHEL documents in a BZ [5] "it served no practical purpose other than to
serve as a potential security problem or to enable binary module drivers
to access structures/functions they shouldn't be touching"
2) /proc/kcore is a decent interface to have a controlled way to read
kernel memory for debugging puposes. (will need some extensions to
deal with memory offlining/unplug, memory ballooning, and poisoned
pages, though)
3) It might be useful for corner case debugging [1]. KDB/KGDB might be a
better fit, especially, to write random memory; harder to shoot
yourself into the foot.
4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems
to be incompatible with 64bit [1]. For educational purposes,
/proc/kcore might be used to monitor value updates -- or older
kernels can be used.
5) It's broken on arm64, and therefore, completely disabled there.
Looks like it's essentially unused and has been replaced by better
suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's
just remove it.

The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
that remains in use on Supermicro X9 server boards among others. Support
gets added for a particular server board using this SoC along with the
basic platform bringup.
As the platform is a predecessor to the npcm7xx platform we already
support, it is added to the same directory, despite using a different
name. It also seems to be related to the older w90x900/nuc9xx platform
that was removed last year.

Update defconfig to have nefilter available as loadable modules

select SIMPLE_PM_BUS so it can be dropped. And some devices use
EEPROM_AT25 so let's add it as a loadable module.

Summary of modules changes for the 5.12 merge window:
- Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These export
types were introduced between 2006 - 2008. All the of the unused symbols have
been long removed and gpl future symbols were converted to gpl quite a long
time ago, and I don't believe these export types have been used ever since.
So, I think it should be safe to retire those export types now. (Christoph Hellwig)
- Refactor and clean up some aged code cruft in the module loader (Christoph Hellwig)
- Build {,module_}kallsyms_on_each_symbol only when livepatching is enabled, as
it is the only caller (Christoph Hellwig)
- Unexport find_module() and module_mutex and fix the last module
callers to not rely on these anymore. Make module_mutex internal to
the module loader. (Christoph Hellwig)
- Harden ELF checks on module load and validate ELF structures before checking
the module signature (Frank van der Linden)
- Fix undefined symbol warning for clang (Fangrui Song)
- Fix smatch warning (Dan Carpenter)

There are a lot of platforms that have not seen any interesting code
changes in the past five years or more.
I made a list and asked around which ones are no longer in use [1], and
received confirmation about six ARM platforms and the TI C6x architecture
that have all reached the end of their life upstream, with no known
users remaining:
- efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
- picoxcell -- added in 2011, abandoned after 2012 acquisition
- prima2 -- added in 20111, no notable changes since 2015
- tango -- added in 2015, sporadic changes until 2017, but abandoned
- u300 -- added in 2009, no notable changes since 2013
- zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
- arch/c6x -- added in 2011, but work stalled soon after that
A number of other platforms on the original list turned out to still
have users. In some cases there are out-of-tree patches and users
that plan to contribute them in the future, in other cases the code
is complete and works reliably.

As all AT91 platforms are converted to DT for a long time, adapt the
defconfigs by:

- removing the CONFIG_ARM_APPENDED_DTB option on SAMA5 devices as the
vast majority of systems will use a DT-aware bootloader on these
devices.

The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

The smp8758 (tango4) SoC was the last generation of set-top-box chips
to come out of Sigma Designs, and support was added by Marc Gonzalez
and Måns Rullgård between 2015 and 2017, before the company went out of
business and the products were abandoned.
The chip is used in some set-top-boxes such as the Popcorn Hour A-500,
which could have seen some adoption by hobbyists. This has not happened
in the past four years, and support for the more widely used MIPS based
SoCs was never merged at all.
Thanks to Marc and Måns for maintaining for the past years even after the
death of the platform.

The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.
However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.
Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.
Thanks to Jun and Shawn for maintaining this platform over the past
five years.

The SiRF Prima2 and Atlas platform code was contributed by Cambridge
Silicon Radio (CSR) after aquiring the original SiRF company, and
maintained by Barry Song. CSR was subsequently acquired by Qualcomm,
who no longer have an interest in maintaining the SoC platform but
instead have released more recent SoCs for the same market in the
Snapdragon family.
As Barry is no longer working for the company, nobody else there
wants to maintain it, and there are no third-party users, the
best way forward seems to be to completely remove it.
Thanks to Barry for maintaining the platform for the past ten years.

- Two small defconfig changes for omap2, to reflect changes in drivers
- Warning fixes for DT issues on omap2, picoxcell and bitmap SoCs.

This cleans up two ancient timer features that were never completed in
the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
of clocksource implementations, the ARM EBSA110 platform. Rather than
changing to use modern timekeeping, we remove the platform entirely as
Russell no longer uses his machine and nobody else seems to have one
any more.
The conditional code for using arch_gettimeoffset() is removed as
a result.
For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
not using clockevent drivers: parisc, ia64, most of m68k, and one
Arm platform. These all do timer ticks slighly differently, and this
gets cleaned up to the point they at least all call the same helper
function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
in Kconfig, the polarity is now reversed, with the few remaining ones
selecting LEGACY_TIMER_TICK instead.

the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
of clocksource implementations, the ARM EBSA110 platform. Rather than
changing to use modern timekeeping, we remove the platform entirely as
Russell no longer uses his machine and nobody else seems to have one
any more.
The conditional code for using arch_gettimeoffset() is removed as a
result.
For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
not using clockevent drivers: parisc, ia64, most of m68k, and one Arm
platform. These all do timer ticks slighly differently, and this gets
cleaned up to the point they at least all call the same helper
function.
Instead of most platforms using 'select GENERIC_CLOCKEVENTS' in
Kconfig, the polarity is now reversed, with the few remaining ones
selecting LEGACY_TIMER_TICK instead"

We can fix this by removing the ZSMALLOC_PGTABLE_MAPPING feature (which
contains the offending calling code) from zsmalloc.
Even though this option showed some amount improvement(e.g., 30%) in
some arm32 platforms, it has been headache to maintain since it have
abused APIs[1](e.g., unmap_kernel_range in atomic context).
Since we are approaching to deprecate 32bit machines and already made
the config option available for only builtin build since v5.8, lastly it
has been not default option in zsmalloc, it's time to drop the option
for better maintenance.

The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf30 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

/lib/firmware directory, it makes sense to have it as a module to have
more control over the loading process.

Drop the separate Kconfig symbol for Xircom / Entrega and always include
support in the keyspan_pda driver.
Note that all configs that enabled CONFIG_USB_SERIAL_XIRCOM also enable
CONFIG_USB_SERIAL_KEYSPAN_PDA.

Russell said that he is no longer using this machine, and it seems that
nobody else has in a long time, so it's time to say goodbye to it.
As this is the last platform using CONFIG_ARCH_USES_GETTIMEOFFSET,
there are some follow-up patches to remove that as well.

The media tree Kconfig has changed recently, and a lot of modules were
built unintentionally, like the dvb frontends and encoders.
Resync the defconfig to build the ISI drivers and tested sensors.

Since commit 12d16b397c ("gpio: mxc: Support module build") the
CONFIG_GPIO_MXC option needs to be explicitly selected.
Select it to avoid boot issues on imx25/imx27 due to the lack of the
GPIO driver.
