initramfs: move the legacy keepinitrd parameter to core code
No need to handle the freeing disable in arch code when we already have a core hook (and a different name for the option) for it.

This is the bulk of the GPIO changes for the v5.2 kernel cycle:
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to
be handled consistently. Unsurprisingly, we enforce the lines to
be either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone
does, so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed.
Such nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs
and outputs at the same time and after improving the MMIO library
we handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM
work as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update.

We have a couple new features and changes in the core clk framework this time
around because we've finally gotten around to fixing some long standing issues.
There's still work to do though, so this PR is largely laying down the
foundation for all the driver changes to come in the next merge window.
The first problem we're alleviating is how parents of clks are specified. With
the new method, we should see lots of drivers migrate away from the current
design of string comparisons on the entire clk tree to a more direct method
where they can use clk_hw pointers or more localized names specified in DT or
via clkdev. This should reduce our reliance on string comparisons for all the
topology description logic that we've been using for years and hopefully speed
some things up while avoiding problems we have with generating clk names.
Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't really
helping anyone and we introduced big-endian versions of the basic clk types so
that we can get rid of clk_{readl,writel}(). Both of these are things that
driver developers have tried to use over the years that I typically bat away
during code reviews because they're not useful. It's great to see these two
things go away so maintainers can save time not worrying about these things.
On the driver side we got the usual collection of new SoC support and
non-critical fixes and updates to existing code. The big topics that stand out
are the new driver support for Mediatek MT8183 and MT8516 SoCs, Amlogic Meson8b
and G12a SoCs, and the SiFive FU540 SoC. The other patches in the driver pile
are mostly fixes for things that are being used for the first time or additions
for clks that couldn't be tested before because there wasn't a consumer driver
that exercised them. Details are below and also in the sub-maintainer tags.
Core:
- Remove clk_readl() and introduce BE versions of basic clk types
- Rewrite how clk parents can be specified to allow DT/clkdev lookups
- Removal of the CLK_IS_BASIC clk flag
- Framework documentation updates and fixes
New Drivers:
- Support for STM32F769

- Qualcomm QCS404 CDSP clk support
- Qualcomm QCS404 Turing clk support
- Mediatek MT8183 clock support
- Mediatek MT8516 clock support
- Milbeaut M10V clk controller support
- Support for Cirrus Logic Lochnagar clks
Updates:
- Rework AT91 sckc DT bindings
- Fix slow RC oscillator issue on sama5d3
- Mark UFS clk as critical on Hi-Silicon hi3660 SoCs
- Various static analysis fixes/finds and const markings
- Video Engine (ECLK) support on Aspeed SoCs

- Convert Xilinx ZynqMP driver to be struct oriented

- Allwinner H6 fixes to support a finer clocking of the video and VPU engines
- Add g12a support in the Amlogic axg audio clock controller
- Add missing PCI USB clock on Rensas RZ/N1
- Add Z2 (Cortex-A53) clocks on Rensas R-Car E3 and RZ/G2E
- A new helper DIV64_U64_ROUND_CLOSEST() in <linux/math64.h>
- VPU and Video Decoder clocks on Amlogic Meson8b
- Finally remove the wrong ABP Meson8b clock id
- Add Video Decoder, PCIe PLL, and CPU Clocks on Amlogic G12A

Pull audit updates from Paul Moore:
"We've got a reasonably broad set of audit patches for the v5.2 merge
window, the highlights are below:
- The biggest change, and the source of all the arch/* changes, is
the patchset from Dmitry to help enable some of the work he is
doing around PTRACE_GET_SYSCALL_INFO.
To be honest, including this in the audit tree is a bit of a
stretch, but it does help move audit a little further along towards
proper syscall auditing for all arches, and everyone else seemed to
agree that audit was a "good" spot for this to land (or maybe they
just didn't want to merge it? dunno.).
- We can now audit time/NTP adjustments.
- We continue the work to connect associated audit records into a
single event"

Staging / IIO driver patches for 5.2-rc1
Here is the big staging and iio driver update for 5.2-rc1.
Lots of tiny fixes all over the staging and IIO driver trees here, along
with some new IIO drivers.
Also we ended up deleting two drivers, making this pull request remove a
few hundred thousand lines of code, always a nice thing to see. Both of
the drivers removed have been replaced with "real" drivers in their
various subsystem directories, and they will be coming to you from those
locations during this merge window.
There are some core vt/selection changes in here, that was due to some
cleanups needed for the speakup fixes. Those have all been acked by the
various subsystem maintainers (i.e. me), so those are ok.
We also added a few new drivers, for some odd hardware, giving new
developers plenty to work on with basic coding style cleanups to come in
the near future.
Other than that, nothing unusual here.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon.

Linus originally suggested to implement this as a new flag to clone() instead of making it a separate system call. After a thorough review from Oleg CLONE_PIDFD returns pidfds in the parent_tidptr argument. This means we can give back the associated pid and the pidfd at the same time. Access to process metadata information thus becomes rather trivial. As has been agreed, CLONE_PIDFD creates file descriptors based on anonymous inodes similar to the new mount api. They are made unconditional by this patchset as they are now needed by core kernel code (vfs, pidfd) even more than they already were before (timerfd, signalfd, io_uring, epoll etc.). The core patchset is rather small. The bulky looking changelist is caused by David's very simple changes to Kconfig to make anon inodes unconditional. A pidfd comes with additional information in fdinfo if the kernel supports procfs. The fdinfo file contains the pid of the process in the callers pid namespace in the same format as the procfs status file, i.e. "Pid:\t%d". To remove worries about missing metadata access this patchset comes with a sample/test program that illustrates how a combination of CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free access to process metadata through /proc/<pid>. Further work based on this patchset has been done by Joel. His work makes pidfds pollable. It finished too late for this merge window. I would prefer to have it sitting in linux-next for a while and send it for inclusion during the 5.3 merge window" * tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: samples: show race-free pidfd metadata access signal: support CLONE_PIDFD with pidfd_send_signal clone: add CLONE_PIDFD Make anon_inodes unconditional |

One small feature was added this release but the bulk of the diffstat
and the changelog comes from the fact that several older drivers got
some fairly hefty reworks and a couple of new drivers were added:
- Support for detailed control of timing around chip selects from
Sowjanya Komatineni.
- A big set of fixes and imrovements for the Tegra114 driver from
Sowjanya Komatineni.
- A big simplification of the GPIO driver from Andrey Smirnov.
- DMA support and fixes for the Freescale LPSPI driver from Clark Wang.
- Fixes and optimizations for the bcm2835aux from Martin Sparl.
- New drivers for Mediatek MT7621 (graduated from staging) and Zynq QSPI.

Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be successfully compiled because they are never built as a module by anyone, i.e, the MODULE_ALIAS() calls are always no-op. A problem showed up when a patch "moduleparam: Save information about built-in modules in separate file" was applied. With this new feature, MODULE_*() will be populated even if the callers are built-in. To avoid the build errors, the lines referencing to the undefined macro must be removed. The complete fix is to remove all MODULE_* and #include <linux/module.h> like many "make ... explicitly non-modular" commits did. For now, I am touching only the offending lines.

Merge branch 'core-stacktrace-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull stack trace updates from Ingo Molnar:
"So Thomas looked at the stacktrace code recently and noticed a few
weirdnesses, and we all know how such stories of crummy kernel code
meeting German engineering perfection end: a 45-patch series to clean
it all up! :-)
Here's the changes in Thomas's words:
'Struct stack_trace is a sinkhole for input and output parameters
which is largely pointless for most usage sites. In fact if embedded
into other data structures it creates indirections and extra storage
overhead for no benefit.
Looking at all usage sites makes it clear that they just require an
interface which is based on a storage array. That array is either on
stack, global or embedded into some other data structure.
Some of the stack depot usage sites are outright wrong, but
fortunately the wrongness just causes more stack being used for
nothing and does not have functional impact.
Another oddity is the inconsistent termination of the stack trace
with ULONG_MAX. It's pointless as the number of entries is what
determines the length of the stored trace. In fact quite some call
sites remove the ULONG_MAX marker afterwards with or without nasty
comments about it. Not all architectures do that and those which do,
do it inconsistenly either conditional on nr_entries == 0 or
unconditionally.
The following series cleans that up by:
1) Removing the ULONG_MAX termination in the architecture code
2) Removing the ULONG_MAX fixups at the call sites
3) Providing plain storage array based interfaces for stacktrace
and stackdepot.
4) Cleaning up the mess at the callsites including some related
cleanups.
5) Removing the struct stack_trace based interfaces
This is not changing the struct stack_trace interfaces at the
architecture level, but it removes the exposure to the generic
code'"

clocksource/arm_arch_timer: Direcly assign set_next_event workaround
When a given timer is affected by an erratum and requires an alternative implementation of set_next_event, we do a rather complicated dance to detect and call the workaround on each set_next_event call. This is clearly idiotic, as we can perfectly detect whether this CPU requires a workaround while setting up the clock event device. This only requires the CPU-specific detection to be done a bit earlier, and we can then safely override the set_next_event pointer if we have a workaround associated to that CPU.

crypto: shash - remove shash_desc::flags
The flags field in 'struct shash_desc' never actually does anything. The only ostensibly supported flag is CRYPTO_TFM_REQ_MAY_SLEEP. However, no shash algorithm ever sleeps, making this flag a no-op. With this being the case, inevitably some users who can't sleep wrongly pass MAY_SLEEP. These would all need to be fixed if any shash algorithm actually started sleeping. For example, the shash_ahash_*() functions, which wrap a shash algorithm with the ahash API, pass through MAY_SLEEP from the ahash API to the shash API. However, the shash functions are called under kmap_atomic(), so actually they're assumed to never sleep. Even if it turns out that some users do need preemption points while hashing large buffers, we could easily provide a helper function crypto_shash_update_large() which divides the data into smaller chunks and calls crypto_shash_update() and cond_resched() for each chunk. It's not necessary to have a flag in 'struct shash_desc', nor is it necessary to make individual shash algorithms aware of this at all. Therefore, remove shash_desc::flags, and document that the crypto_shash_*() functions can be called from any context.

ARM: 8857/1: efi: enable CP15 DMB instructions before cleaning the cache
The EFI stub is entered with the caches and MMU enabled by the firmware, and once the stub is ready to hand over to the decompressor, we clean and disable the caches. The cache clean routines use CP15 barrier instructions, which can be disabled via SCTLR. Normally, when using the provided cache handling routines to enable the caches and MMU, this bit is enabled as well. However, but since we entered the stub with the caches already enabled, this routine is not executed before we call the cache clean routines, resulting in undefined instruction exceptions if the firmware never enabled this bit. So set the bit explicitly in the EFI entry code, but do so in a way that guarantees that the resulting code can still run on v6 cores as well (which are guaranteed to have CP15 barriers enabled) Cc: <stable@vger.kernel.org> # v4.9+ Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> |

ARM: fix function graph tracer and unwinder dependencies
Naresh Kamboju recently reported that the function-graph tracer crashes on ARM. The function-graph tracer assumes that the kernel is built with frame pointers. We explicitly disabled the function-graph tracer when building Thumb2, since the Thumb2 ABI doesn't have frame pointers. We recently changed the way the unwinder method was selected, which seems to have made it more likely that we can end up with the function- graph tracer enabled but without the kernel built with frame pointers. Fix up the function graph tracer dependencies so the option is not available when we have no possibility of having frame pointers, and adjust the dependencies on the unwinder option to hide the non-frame pointer unwinder options if the function-graph tracer is enabled.

But skcipher_walk_virt() can fail afterwards, and then if the caller unconditionally accesses walk.iv, it's a use-after-free. arm32 xts-aes-neonbs doesn't set an alignmask, so currently it isn't affected by this despite unconditionally accessing walk.iv. However this is more subtle than desired, and it was actually broken prior to the alignmask being removed by commit |

mtd: rawnand: Clarify Kconfig entry MTD_NAND
MTD_NAND is large and encloses much more than what the symbol is actually used for: raw NAND. Clarify the symbol by naming it MTD_RAW_NAND instead. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> |

mtd: nand: Clarify Kconfig entry for software Hamming ECC entries
The software Hamming ECC correction implementation is referred as MTD_NAND_ECC which is too generic. Rename it MTD_NAND_ECC_SW_HAMMING. Also rename MTD_NAND_ECC_SMC which is an SMC quirk in the Hamming implementation as MTD_NAND_ECC_SW_HAMMING_SMC. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> |
