commit b52343d1cb47bb27ca32a3f4952cc2fd3cd165bf upstream.
The current logic to split the 64-bit argument into its 32-bit halves is
byte-order specific and a bit clunky. Use a union instead which is
easier to read and works in all cases.
GCC still generates the same machine code.
While at it, rename the arguments of the __memset64() prototype to
actually reflect their semantics.

commit 8678591b47469fe16357234efef9b260317b8be4 upstream.
Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in
vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it
from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and
ELF_DETAILS was present in all architecture specific vmlinux linker
scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and
COMMON_DISCARDS may be used by other linker scripts, such as the s390
and x86 compressed boot images, which may not expect to have a .modinfo
section. In certain circumstances, this could result in a bootloader
failing to load the compressed kernel [1].
Commit ddc6cbef3ef1 ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with
SecureBoot trailer") recently addressed this for the s390 bzImage but
the same bug remains for arm, parisc, and x86. The presence of .modinfo
in the x86 bzImage was the root cause of the issue worked around with
commit d50f21091358 ("kbuild: align modinfo section for Secureboot
Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes
lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its
MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition.
Split .modinfo out from ELF_DETAILS into its own macro and handle it in
all vmlinux linker scripts. Discard .modinfo in the places where it was
previously being discarded from being in COMMON_DISCARDS, as it has
never been necessary in those uses.

[ Upstream commit 93a04ab480c8bbcb7d9004be139c538c8a0c1bc8 ]
The of_get_child_by_name() function increments the reference count
of child nodes, causing multiple reference leaks in omap_control_init():
1. scm_conf node never released in normal/error paths
2. clocks node leak when checking existence
3. Missing scm_conf release before np in error paths
Fix these leaks by adding proper of_node_put() calls and separate error
handling.

[ Upstream commit 0b2761eb1287bd9f62367cccf6626eb3107cef6f ]
The P66's device tree includes the reference design dtsi files, which
defines a node and properties for the touchpanel in the common design.
The P66 dts file then overrides all the properties to match its own
design, but as the touchpanel model is different, a different schema
is matched. This other schema uses a different name for the GPIO.
The original submission added the correct GPIO property, but did not
delete the one inherited from the reference design, causing validation
errors.
Explicitly delete the incorrect GPIO property.

[ Upstream commit fedadc4137234c3d00c4785eeed3e747fe9036ae ]
gup_pgd_range() is invoked with disabled interrupts and invokes
__kmap_local_page_prot() via pte_offset_map(), gup_p4d_range().
With HIGHPTE enabled, __kmap_local_page_prot() invokes kmap_high_get()
which uses a spinlock_t via lock_kmap_any(). This leads to an
sleeping-while-atomic error on PREEMPT_RT because spinlock_t becomes a
sleeping lock and must not be acquired in atomic context.
The loop in map_new_virtual() uses wait_queue_head_t for wake up which
also is using a spinlock_t.
Since HIGHPTE is rarely needed at all, turn it off for PREEMPT_RT
to allow the use of get_user_pages_fast().

[ Upstream commit edb924a7211c9aa7a4a415e03caee4d875e46b8e ]
In the inline assembly inside load_unaligned_zeropad(), the "addr" is
constrained as input-only operand. The compiler assumes that on exit
from the asm statement these operands contain the same values as they
had before executing the statement, but when kernel page fault happened, the assembly fixup code "bic %2 %2, #0x3" modify the value of "addr", which may lead to an unexpected behavior.
Use a temporary variable "tmp" to handle it, instead of modifying the
input-only operand, just like what arm64's load_unaligned_zeropad()
does.

[ Upstream commit 9c95fc710b0d05f797db9e26d56524efa74f8978 ]
Without a serial console speed specified in chosen/stdout-path in the
DTB, the serial console uses the default speed of the serial driver,
unless explicitly overridden in a legacy console= kernel command-line
parameter.
After dropping "ti,omap3-uart" from the list of compatible values in DT,
AM33xx serial ports can no longer be used with the legacy OMAP serial
driver, but only with the OMAP-flavored 8250 serial driver (which is
mutually-exclusive with the former). However, replacing
CONFIG_SERIAL_OMAP=y by CONFIG_SERIAL_8250_OMAP=y (with/without enabling
CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP) may not be sufficient to restore
serial console functionality: the legacy OMAP serial driver defaults to
115200 bps, while the 8250 serial driver defaults to 9600 bps, causing
no visible output on the serial console when no appropriate console=
kernel command-line parameter is specified.
Fix this for all AM33xx boards by adding ":115200n8" to
chosen/stdout-path. This requires replacing the "&uartN" reference by
the corresponding "serialN" DT alias.

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.

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.

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:

for good.

removed the obsolete EXT3_CONFIG options, since it had been over a

commit didn't fix up. This led to a large number of defconfig test

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.

- 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

Enable support for ftrace's funcgraph-retval feature by capturing r0-r3
and fp.
Since ARM does not provide its own __arch_ftrace_regs structure,
we instead populate pt_regs with the registers required by ftrace.

We can use string choices helper, let's use it.
It makes one line code.
