Pull sound fixes from Takashi Iwai:
"As usual in a late stage, we received a fair amount of fixes for ASoC,
and it became bigger than wished. But all fixes are rather device-
specific, and they look pretty safe to apply.
A major par of changes are series of fixes for ASoC meson and SOF
drivers as well as for Realtek and Cirrus codecs. In addition, recent
emu10k1 regression fixes and usual HD-audio quirks are included"

Let's use the newly-free PTE SW bit (58) to add support for uffd-wp.
The standard handlers are implemented for set/test/clear for both pte
and pmd. Additionally we must also track the uffd-wp state as a pte swp
bit, so use a free swap pte bit (3).

PTE_PRESENT_INVALID was previously occupying bit 59, which when a PTE is
valid can either be IGNORED, PBHA[0] or AttrIndex[3], depending on the
HW configuration. In practice this is currently not a problem because
PTE_PRESENT_INVALID can only be 1 when PTE_VALID=0 and upstream Linux
always requires the bit set to 0 for a valid pte.
However, if in future Linux wants to use the field (e.g. AttrIndex[3])
then we could end up with confusion when PTE_PRESENT_INVALID comes along
and corrupts the field - we would ideally want to preserve it even for
an invalid (but present) pte.
The other problem with bit 59 is that it prevents the offset field of a
swap entry within a swap pte from growing beyond 51 bits. By moving
PTE_PRESENT_INVALID to a low bit we can lay the swap pte out so that the
offset field could grow to 52 bits in future.
So let's move PTE_PRESENT_INVALID to overlay PTE_NG (bit 11).
There is no need to persist NG for a present-invalid entry; it is always
set for user mappings and is not used by SW to derive any state from the
pte. PTE_NS was considered instead of PTE_NG, but it is RES0 for
non-secure SW, so there is a chance that future architecture may
allocate the bit and we may therefore need to persist that bit for
present-invalid ptes.
These are both marginal benefits, but make things a bit tidier in my
opinion.

Currently the PTE_PRESENT_INVALID and PTE_PROT_NONE functionality
explicitly occupy 2 bits in the PTE when PTE_VALID/PMD_SECT_VALID is
clear. This has 2 significant consequences:
- PTE_PROT_NONE consumes a precious SW PTE bit that could be used for
other things.
- The swap pte layout must reserve those same 2 bits and ensure they
are both always zero for a swap pte. It would be nice to reclaim at
least one of those bits.
But PTE_PRESENT_INVALID, which since the previous patch, applies
uniformly to page/block descriptors at any level when PTE_VALID is
clear, can already give us most of what PTE_PROT_NONE requires: If it is
set, then the pte is still considered present; pte_present() returns
true and all the fields in the pte follow the HW interpretation (e.g. SW
can safely call pte_pfn(), etc). But crucially, the HW treats the pte as
invalid and will fault if it hits.
So let's remove PTE_PROT_NONE entirely and instead represent PROT_NONE
as a present but invalid pte (PTE_VALID=0, PTE_PRESENT_INVALID=1) with
PTE_USER=0 and PTE_UXN=1. This is a unique combination that is not used
anywhere else.
The net result is a clearer, simpler, more generic encoding scheme that
applies uniformly to all levels. Additionally we free up a PTE SW bit
and a swap pte bit (bit 58 in both cases).

As preparation for the next patch, which frees up the PTE_PROT_NONE
present pte and swap pte bit, generalize PMD_PRESENT_INVALID to
PTE_PRESENT_INVALID. This will then be used to mark PROT_NONE ptes (and
entries at any other level) in the next patch.
While we're at it, fix up the swap pte format comment to include
PTE_PRESENT_INVALID. This is not new, it just wasn't previously
documented.

Fix the cmdline parsing of the "blkdevparts=" parameter using strsep(),
which makes the code simpler.
Before commit 146afeb235cc ("block: use strscpy() to instead of
strncpy()"), we used a strncpy() to copy a block device name and partition
names. The commit simply replaced a strncpy() and NULL termination with
a strscpy(). It did not update calculations of length passed to strscpy().
While the length passed to strncpy() is just a length of valid characters
without NULL termination ('\0'), strscpy() takes it as a length of the
destination buffer, including a NULL termination.
Since the source buffer is not necessarily NULL terminated, the current
code copies "length - 1" characters and puts a NULL character in the
destination buffer. It replaces the last character with NULL and breaks
the parsing.
As an example, that buffer will be passed to parse_parts() and breaks
parsing sub-partitions due to the missing ')' at the end, like the
following.
example (Check Point V-80 & OpenWrt):

By the way, strscpy() takes a length of destination buffer and it is
often confusing when copying characters with a specified length. Using
strsep() helps to separate the string by the specified character. Then,
we can use strscpy() naturally with the size of the destination buffer.
Separating the string on the fly is also useful to omit the redundant
string copy, reducing memory usage and improve the code readability.

Since the fsverity sysctl registration runs as a builtin initcall, there
is no corresponding sysctl deregistration and the resulting struct
ctl_table_header is not used. This can cause a kmemleak warning just
after the system boots up. (A pointer to the ctl_table_header is stored
in the fsverity_sysctl_header static variable, which kmemleak should
detect; however, the compiler can optimize out that variable.) Avoid
the kmemleak warning by using register_sysctl_init() which is intended
for use by builtin initcalls and uses kmemleak_not_leak().

The per-architecture fbdev code has no dependencies on fbdev and can
be used for any video-related subsystem. Rename the files to 'video'.
Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE.
On arc, arm, arm64, sh, and um the asm header file is an empty wrapper
around the file in asm-generic. Let Kbuild generate the file. The build
system does this automatically. Only um needs to generate video.h
explicitly, so that it overrides the host architecture's header. The
latter would otherwise interfere with the build.
Further update all includes statements, include guards, and Makefiles.
Also update a few strings and comments to refer to video instead of
fbdev.

Various Kconfig options selected the per-architecture helpers for

on CONFIG_VIDEO, which will allow to add more general helpers for

CONFIG_VIDEO protects each architecture's video/ directory. This
allows for the use of more fine-grained control for each directory's

Change the return types of bitops functions (ffs, fls, and fns) from
long to int. The expected return values are in the range [0, 64], for
which int is sufficient.
Additionally, int aligns well with the return types of the corresponding
__builtin_* functions, potentially reducing overall type conversions.
Many of the existing bitops functions already return an int and don't
need to be changed. The bitops functions in arch/ should be considered
separately.
Adjust some return variables to match the function return types.
With GCC 13 and defconfig, these changes reduced the size of a test
kernel image by 5,432 bytes on arm64 and by 248 bytes on riscv; there
were no changes in size on x86_64, powerpc, or m68k.

quotes
Drop unnecessary quotes which aren't needed in yaml. This is checked by
yamllint, but this case was excluded due to the comma and yamllint's
mishandling of some cases with commas. That's now fixed in yamllint
1.34.

The __find_rmem() function is the only place that references the phandle
field of the reserved_mem struct. __find_rmem() is used to match a
device_node object to its corresponding entry in the reserved_mem array
using its phandle value. But, there is already a function called
of_reserved_mem_lookup() which carries out the same action using the
name of the node.
Using the of_reserved_mem_lookup() function is more reliable because
every node is guaranteed to have a name, but not all nodes will have a
phandle.
Nodes are only assigned a phandle if they are explicitly defined in the
DT using "phandle = <phandle_number>", or if they are referenced by
another node in the DT. Hence, If the phandle field is empty, then
__find_rmem() will return a false negative.
Hence, delete the __find_rmem() function and switch to using the
of_reserved_mem_lookup() function to find the corresponding entry of a
device_node in the reserved_mem array. Since the phandle field of the
reserved_mem struct is now unused, delete that as well.

For development purpose, renesas_sdhi_probe() could be called w/
dma_ops = NULL to force the usage of PIO mode. In this case the
renesas_sdhi_enable_dma() will not be called before transferring data.
If renesas_sdhi_enable_dma() is not called, renesas_sdhi_clk_enable()
call from renesas_sdhi_probe() will configure SDBUF by calling the
renesas_sdhi_sdbuf_width() function, but then SDBUF will be reset in
tmio_mmc_host_probe() when calling tmio_mmc_reset() though host->reset().
If SDBUF is zero the data transfer will not work in PIO mode for RZ/G3S.
To fix this call again the renesas_sdhi_sdbuf_width(host, 16) in
renesas_sdhi_reset(). The call of renesas_sdhi_sdbuf_width() was not
removed from renesas_sdhi_clk_enable() as the host->reset() is optional.

Joel Granados says:
====================
sysctl: Remove sentinel elements from networking
What?
These commits remove the sentinel element (last empty element) from the
sysctl arrays of all the files under the "net/" directory that register
a sysctl array. The merging of the preparation patches [4] to mainline
allows us to just remove sentinel elements without changing behavior.
This is safe because the sysctl registration code (register_sysctl() and
friends) use the array size in addition to checking for a sentinel [1].
Why?
By removing the sysctl sentinel elements we avoid kernel bloat as
ctl_table arrays get moved out of kernel/sysctl.c into their own
respective subsystems. This move was started long ago to avoid merge
conflicts; the sentinel removal bit came after Mathew Wilcox suggested
it to avoid bloating the kernel by one element as arrays moved out. This
patchset will reduce the overall build time size of the kernel and run
time memory bloat by about ~64 bytes per declared ctl_table array (more
info here [5]).
When are we done?
There are 4 patchest (25 commits [2]) that are still outstanding to
completely remove the sentinels: files under "net/" (this patchset),
files under "kernel/" dir, misc dirs (files under mm/ security/ and
others) and the final set that removes the unneeded check for ->procname
== NULL.
Testing:
* Ran sysctl selftests (./tools/testing/selftests/sysctl/sysctl.sh)
* Ran this through 0-day with no errors or warnings
Savings in vmlinux:
A total of 64 bytes per sentinel is saved after removal; I measured in
x86_64 to give an idea of the aggregated savings. The actual savings
will depend on individual kernel configuration.
* bloat-o-meter
- The "yesall" config saves 3976 bytes (bloat-o-meter output [6])
- A reduced config [3] saves 1263 bytes (bloat-o-meter output [7])
Savings in allocated memory:
None in this set but will occur when the superfluous allocations are
removed from proc_sysctl.c. I include it here for context. The
estimated savings during boot for config [3] are 6272 bytes. See [8]
for how to measure it.
Comments/feedback greatly appreciated
Changes in v6:
- Rebased onto net-next/main.
- Besides re-running my cocci scripts, I ran a new find script [9].
Found 0 hits in net/
- Moved "i" variable declaraction out of for() in sysctl_core_net_init
- Removed forgotten sentinel in mpls_table
- Removed CONFIG_AX25_DAMA_SLAVE guard from net/ax25/ax25_ds_timer.c. It
is not needed because that file is compiled only when
CONFIG_AX25_DAMA_SLAVE is set.
- When traversing smc_table, stop on ARRAY_SIZE instead of ARRAY_SIZE-1.

This commit comes at the tail end of a greater effort to remove the
empty elements at the end of the ctl_table arrays (sentinels) which will
reduce the overall build time size of the kernel and run time memory
bloat by ~64 bytes per sentinel (further information Link :
https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/)
Avoid a buffer overflow when traversing the ctl_table by ensuring that
AX25_MAX_VALUES is the same as the size of ax25_param_table. This is
done with a BUILD_BUG_ON where ax25_param_table is defined and a
CONFIG_AX25_DAMA_SLAVE guard in the unnamed enum definition as well as
in the ax25_dev_device_up and ax25_ds_set_timer functions.
The overflow happened when the sentinel was removed from
ax25_param_table. The sentinel's data element was changed when
CONFIG_AX25_DAMA_SLAVE was undefined. This had no adverse effects as it
still stopped on the sentinel's null procname but needed to be addressed
once the sentinel was removed.

Similar to what has already been changed for eMMC and the MMC_SEND_OP_COND
(CMD1), let's convert the SD_APP_OP_COND (ACMD41) for SD cards to use the
common __mmc_poll_for_busy() too.
This change means the initial delay period, that starts as 10ms will now
increase for every loop when being busy. The total accepted timeout for
being busy is 1s, which is according to the SD spec.

MIPS CPUs usually have 1 to 4 cycles load hazards, thus doing load
and right after move to HI/LO will usually stall the pipeline for
significant amount of time. Let's take it into account and separate
loads and mthi/lo in instruction sequence.
The patch uses t6 and t7 registers as temporaries in addition to t8.
The patch tries to deal with SmartMIPS, but I know little about and
haven't tested it.

The mmu600_pcie is connected with the five PCIe controllers.
The mmu600_php is connected with the USB3 controller, the GMAC
controllers, and the SATA controllers.
See 8.2 Block Diagram, in rk3588 TRM (Technical Reference Manual).
The IOMMUs are disabled by default, as further patches are needed to
program the SID/SSIDs in to the IOMMUs.
iommu: Default domain type: Translated
iommu: DMA domain TLB invalidation policy: strict mode
arm-smmu-v3 fc900000.iommu: ias 48-bit, oas 48-bit (features 0x001c1eaf)
arm-smmu-v3 fc900000.iommu: allocated 65536 entries for cmdq
arm-smmu-v3 fc900000.iommu: allocated 32768 entries for evtq
arm-smmu-v3 fc900000.iommu: msi_domain absent - falling back to wired irqs
Additionally, the IOMMU correctly triggers an IOMMU fault when
a PCIe device performs a write (since the device hasn't been
assigned a SID/SSID):
arm-smmu-v3 fc900000.iommu: event 0x02 received:
arm-smmu-v3 fc900000.iommu: 0x0000010000000002
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
arm-smmu-v3 fc900000.iommu: 0x0000000000000000
While this doesn't provide much value as is, having the devices as
disabled in the device tree will allow developers to see that the rk3588
actually has IOMMUs on the SoC.
