The i.MX6UL reference manual lists two possible interrupt lines for
SAI3 (56 and 57, offset +32). The current device tree entry uses
the first one (24), which prevents IRQs from being handled properly.
Use the second interrupt line (25), which does allow interrupts
to work as expected.

In former times, ext4 was enabled implicitely by enabling ext3 but with
the ext3 fs gone, it does not get enabled, which lets devices fail to
mount root on non-initrd based boots with an ext4 root.

Rename the 'ssi2' and 'aud3' nodes to 'mux-ssi2' and 'mux-aud3' in the
audmux configuration of imx51-zii-rdu1.dts to comply with the naming
convention in imx-audmux.yaml.

The 'report-rate-hz' property for the edt-ft5x06 driver was added and
handled in the Linux kernel by me with patches [1] and [2] for this
specific board.
The v1 upstream version, which was the one applied to the customer's
kernel, used the 'report-rate' property, which was written directly to
the controller register. During review, the 'hz' suffix was added,
changing its handling so that writing the value directly to the register
was no longer possible for the M06 controller.
Once the patches were accepted in mainline, I did not reapply them to
the customer's kernel, and when upstreaming the DTS for this board, I
forgot to correct the 'report-rate-hz' property value.
The property must be set to 60 because this board uses the M06 controller,
which expects the report rate in units of 10 Hz, meaning the actual value
written to the register is 6.

"mac3" controller was removed from the initial version of fuji-data64
dts because the rgmii setting is incorrect, but dropping mac3 leads to
regression in the existing fuji platform, because fuji.dts simply
includes fuji-data64.dts.
This patch adds mac3 back to fuji-data64.dts to fix the fuji regression[1],
and rgmii settings need to be fixed later.

Until commit 919d6924ae9b ("clk: bcm: rpi: Turn firmware clock on/off
when preparing/unpreparing") the clk-raspberrypi driver wasn't able
to change the state of the V3D clock. Only the clk-bcm2835 was able
to do this before. After this commit both drivers were able to work
against each other, which could result in a system freeze. One step
to avoid this conflict is to switch all V3D consumer to the firmware
clock.

Inspired by commit c065b6046b34 ("Use CONFIG_EXT4_FS instead of
CONFIG_EXT3_FS in all of the defconfigs") I looked around for any other
left-over EXT3 config options, and found some old defconfig files still
mentioned CONFIG_EXT3_DEFAULTS_TO_ORDERED.
That config option was removed a decade ago in commit c290ea01abb7 ("fs:
Remove ext3 filesystem driver"). It had a good run, but let's remove it
for good.

Commit d6ace46c82fd ("ext4: remove obsolete EXT3 config options")
removed the obsolete EXT3_CONFIG options, since it had been over a
decade since fs/ext3 had been removed. Unfortunately, there were a
number of defconfigs that still used CONFIG_EXT3_FS which the cleanup
commit didn't fix up. This led to a large number of defconfig test
builds to fail. Oops.

Lots of functions in mm/highmem.c do not write to the given pointers and
do not call functions that take non-const pointers and can therefore be
constified.
This includes functions like kunmap() which might be implemented in a way
that writes to the pointer (e.g. to update reference counters or mapping
fields), but currently are not.
kmap() on the other hand cannot be made const because it calls
set_page_address() which is non-const in some
architectures/configurations.

Call kasan_init_generic() which handles Generic KASAN initialization. For
architectures that do not select ARCH_DEFER_KASAN, this will be a no-op
for the runtime flag but will print the initialization banner.
For SW_TAGS and HW_TAGS modes, their respective init functions will handle
the flag enabling, if they are enabled/implemented.

Patch series "Add and use memdesc_flags_t".
At some point struct page will be separated from struct slab and struct
folio. This is a step towards that by introducing a type for the 'flags'
word of all three structures. This gives us a certain amount of type
safety by establishing that some of these unsigned longs are different
from other unsigned longs in that they contain things like node ID,
section number and zone number in the upper bits. That lets us have
functions that can be easily called by anyone who has a slab, folio or
page (but not easily by anyone else) to get the node or zone.
There's going to be some unusual merge problems with this as some odd bits
of the kernel decide they want to print out the flags value or something
similar by writing page->flags and now they'll need to write page->flags.f
instead. That's most of the churn here. Maybe we should be removing
these things from the debug output?
This patch (of 11):
Wrap the unsigned long flags in a typedef. In upcoming patches, this will
provide a strong hint that you can't just pass a random unsigned long to
functions which take this as an argument.

Pull block updates from Jens Axboe:
- NVMe pull request via Keith:
- FC target fixes (Daniel)
- Authentication fixes and updates (Martin, Chris)
- Admin controller handling (Kamaljit)
- Target lockdep assertions (Max)
- Keep-alive updates for discovery (Alastair)
- Suspend quirk (Georg)
- MD pull request via Yu:
- Add support for a lockless bitmap.
A key feature for the new bitmap are that the IO fastpath is
lockless. If a user issues lots of write IO to the same bitmap
bit in a short time, only the first write has additional overhead
to update bitmap bit, no additional overhead for the following
writes.
By supporting only resync or recover written data, means in the
case creating new array or replacing with a new disk, there is no
need to do a full disk resync/recovery.
- Switch ->getgeo() and ->bios_param() to using struct gendisk rather
than struct block_device.
- Rust block changes via Andreas. This series adds configuration via
configfs and remote completion to the rnull driver. The series also
includes a set of changes to the rust block device driver API: a few
cleanup patches, and a few features supporting the rnull changes.
The series removes the raw buffer formatting logic from
`kernel::block` and improves the logic available in `kernel::string`
to support the same use as the removed logic.
- floppy arch cleanups
- Reduce the number of dereferencing needed for ublk commands
- Restrict supported sockets for nbd. Mostly done to eliminate a class
of issues perpetually reported by syzbot, by using nonsensical socket
setups.
- A few s390 dasd block fixes
- Fix a few issues around atomic writes
- Improve DMA interation for integrity requests
- Improve how iovecs are treated with regards to O_DIRECT aligment
constraints.
We used to require each segment to adhere to the constraints, now
only the request as a whole needs to.
- Clean up and improve p2p support, enabling use of p2p for metadata
payloads
- Improve locking of request lookup, using SRCU where appropriate
- Use page references properly for brd, avoiding very long RCU sections
- Fix ordering of recursively submitted IOs
- Clean up and improve updating nr_requests for a live device
- Various fixes and cleanups

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, the first depends line of
ARM_HAS_GROUP_RELOCS is always true, so it can be safely removed.
Combine the !COMPILE_TEST dependency into the 'def_bool' line and update
the comment as well.

Commit d1bef995f61a ("ARM: rockchip: force built-in regulator support for PM")
introduced the REGULATOR if PM dependency for the suspend code, while
commit d1558dfd9f22 ("ARM: rockchip: Force CONFIG_PM on Rockchip systems")
later always enabled PM.
So we can simplify the REGULATOR dependency by dropping the if PM.

This improves readability and consistency across

There is an issue possible where TI AM33xx SoCs do not boot properly after
a reset if EMU0/EMU1 pins were used as GPIO and have been driving low level
actively prior to reset [1].
"Advisory 1.0.36 EMU0 and EMU1: Terminals Must be Pulled High Before
ICEPick Samples
The state of the EMU[1:0] terminals are latched during reset to determine
ICEPick boot mode. For normal device operation, these terminals must be
pulled up to a valid high logic level ( > VIH min) before ICEPick samples
the state of these terminals, which occurs
[five CLK_M_OSC clock cycles - 10 ns] after the falling edge of WARMRSTn.
Many applications may not require the secondary GPIO function of the
EMU[1:0] terminals. In this case, they would only be connected to pull-up
resistors, which ensures they are always high when ICEPick samples.
However, some applications may need to use these terminals as GPIO where
they could be driven low before reset is asserted. This usage of the
EMU[1:0] terminals may require special attention to ensure the terminals
are allowed to return to a valid high-logic level before ICEPick samples
the state of these terminals.
When any device reset is asserted, the pin mux mode of EMU[1:0] terminals
configured to operate as GPIO (mode 7) will change back to EMU input
(mode 0) on the falling edge of WARMRSTn. This only provides a short period
of time for the terminals to return high if driven low before reset is
asserted...
If the EMU[1:0] terminals are configured to operate as GPIO, the product
should be designed such these terminals can be pulled to a valid high-logic
level within 190 ns after the falling edge of WARMRSTn."
We've noticed this problem with custom am335x hardware in combination with
recently implemented cold reset method
(commit 6521f6a195c70 ("ARM: AM33xx: PRM: Implement REBOOT_COLD")).
It looks like the problem can affect other HW, for instance AM335x
Chiliboard, because the latter has LEDs on GPIO3_7/GPIO3_8 as well.
One option would be to check if the pins are in GPIO mode and either switch
to output active high, or switch to input and poll until the external
pull-ups have brought the pins to the desired high state. But fighting
with GPIO driver for these pins is probably not the most straight forward
approch in a reboot handler.
Fortunately we can easily control pinmuxing here and rely on the external
pull-ups. TI recommends 4k7 external pull up resistors [2] and even with
quite conservative estimation for pin capacity (1 uF should never happen)
the required delay shall not exceed 5ms.

The at91_mckx_ps_restore() assembly function is responsible for setting
back MCKx system bus clocks after exiting low power modes.
Fix a typo and use tmp3 variable instead of tmp2 to correctly set MCKx
to previously saved state.
Tmp2 was used without the needed changes in CSS and DIV. Moreover the
required bit 7, telling that MCR register's content is to be changed
(CMD/write), was not set.
Fix function comment to match tmp variables actually used.

Having a platform need a mach-* directory should be seen as a negative,
it means the platform needs special non-standard handling. ARM64 support
does not allow mach-* directories at all. While we may not get to that
given all the non-standard architectures we support, we should still try
to get as close as we can and reduce the number of mach directories.
The mach-hpe/ directory and files, provides just one "feature":
having the kernel print the machine name if the DTB does not also contain
a "model" string (which they always do). To reduce the number of mach-*
directories let's do without that feature and remove this directory.
Note, we drop the l2c_aux_mask = ~0 line, but this is safe as
the fallback GENERIC_DT machine has that as the default.
