All new drivers should use fwnode and / or parent to provide the
necessary information to the GPIO library.

There are no more users of these APIs in the mainline kernel, remove
them. This leaves of_get_named_gpio() as the only legacy OF-specific

The DRM fbdev emulation layer sets the struct fb_info .fbdefio field to
a struct fb_deferred_io pointer, that is shared across all drivers that
use the generic drm_fbdev_generic_setup() helper function.
It is a problem because the fbdev core deferred I/O logic assumes that
the struct fb_deferred_io data is not shared between devices, and it's
stored there state such as the list of pages touched and a mutex that
is use to synchronize between the fb_deferred_io_track_page() function
that track the dirty pages and fb_deferred_io_work() workqueue handler
doing the actual deferred I/O.
The latter can lead to the following error, since it may happen that two
drivers are probed and then one is removed, which causes the mutex bo be
destroyed and not existing anymore by the time the other driver tries to
grab it for the fbdev deferred I/O logic:

Currently there is no easy way for a drm driver to safely check and allow
drm_vma_offset_node for a drm file just once. Allow drm drivers to call
non-refcounted version of drm_vma_node_allow() so that a driver doesn't
need to keep track of each drm_vma_node_allow() to call subsequent
drm_vma_node_revoke() to prevent memory leak.

Add a new (static inline) apple_gmux_detect() helper to apple-gmux.h
which can be used for gmux detection instead of apple_gmux_present().
The latter is not really reliable since an ACPI device with a HID
of APP000B is present on some devices without a gmux at all, as well
as on devices with a newer (unsupported) MMIO based gmux model.
This causes apple_gmux_present() to return false-positives on
a number of different Apple laptop models.
This new helper uses the same probing as the actual apple-gmux
driver, so that it does not return false positives.
To avoid code duplication the gmux_probe() function of the actual
driver is also moved over to using the new apple_gmux_detect() helper.
This avoids false positives (vs _HID + IO region detection) on:

This is a preparation patch for adding a new static inline
apple_gmux_detect() helper which actually checks a supported
gmux is present, rather then only checking an ACPI device with
the HID is there as apple_gmux_present() does.

An SCTP endpoint can start an association through a path and tear it
down over another one. That means the initial path will not see the
shutdown sequence, and the conntrack entry will remain in ESTABLISHED
state for 5 days.
By merging the HEARTBEAT_ACKED and ESTABLISHED states into one
ESTABLISHED state, there remains no difference between a primary or
secondary path. The timeout for the merged ESTABLISHED state is set to
210 seconds (hb_interval * max_path_retrans + rto_max). So, even if a
path doesn't see the shutdown sequence, it will expire in a reasonable
amount of time.
With this change in place, there is now more than one state from which
we can transition to ESTABLISHED, COOKIE_ECHOED and HEARTBEAT_SENT, so
handle the setting of ASSURED bit whenever a state change has happened
and the new state is ESTABLISHED. Removed the check for dir==REPLY since
the transition to ESTABLISHED can happen only in the reply direction.

This reverts commit (bff3d0534804: "netfilter: conntrack: add sctp
DATA_SENT state")
Using DATA/SACK to detect a new connection on secondary/alternate paths
works only on new connections, while a HEARTBEAT is required on
connection re-use. It is probably consistent to wait for HEARTBEAT to
create a secondary connection in conntrack.

The PCI and queue number info is missing in IRQ names.
Add PCI and queue number to IRQ names, to allow CPU affinity

The biggest are the UFS devfreq fixes which address a lock inversion
and the two iscsi_tcp fixes which try to prevent a use after free from
userspace still accessing an area which the kernel has released (seen
by KASAN)"

We can easily reproduce by two tasks:
1. while :; do iscsiadm -m node --login; iscsiadm -m node --logout; done
2. while :; do cat \
/sys/devices/platform/host*/iscsi_host/host*/ipaddress; done
iscsid | cat

| |- iscsi_sw_tcp_host_get_param
| |- r/w tcp_sw_host->session (UAF)
|- iscsi_host_remove |
|- iscsi_host_free |
Fix the above bug by splitting the session removal into 2 parts:
1. removal from iSCSI class which includes sysfs and removal from host
tracking.
2. freeing of session.
During iscsi_tcp host and session removal we can remove the session from
sysfs then remove the host from sysfs. At this point we know userspace is
not accessing the kernel via sysfs so we can free the session and host.

There is a lock inversion and rwsem read-lock recursion in the devfreq
target callback which can lead to deadlocks.
Specifically, ufshcd_devfreq_scale() already holds a clk_scaling_lock
read lock when toggling the write booster, which involves taking the
dev_cmd mutex before taking another clk_scaling_lock read lock.
This can lead to a deadlock if another thread:
1) tries to acquire the dev_cmd and clk_scaling locks in the correct
order, or
2) takes a clk_scaling write lock before the attempt to take the
clk_scaling read lock a second time.
Fix this by dropping the clk_scaling_lock before toggling the write booster
as was done before commit 0e9d4ca43ba8 ("scsi: ufs: Protect some contexts
from unexpected clock scaling").
While the devfreq callbacks are already serialised, add a second
serialising mutex to handle the unlikely case where a callback triggered
through the devfreq sysfs interface is racing with a request to disable
clock scaling through the UFS controller 'clkscale_enable' sysfs
attribute. This could otherwise lead to the write booster being left
disabled after having disabled clock scaling.
Also take the new mutex in ufshcd_clk_scaling_allow() to make sure that any
pending write booster update has completed on return.
Note that this currently only affects Qualcomm platforms since commit
87bd05016a64 ("scsi: ufs: core: Allow host driver to disable wb toggling
during clock scaling").
The lock inversion (i.e. 1 above) was reported by lockdep as:

The struct device driver-data pointer is used for any data that a driver
may need in various callbacks while bound to the device. For
convenience, subsystems typically provide wrappers such as
usb_set_intfdata() of the generic accessor functions for use in bus
callbacks.
There is generally no longer any need for a driver to clear the pointer,
but since commit 0998d0631001 ("device-core: Ensure drvdata = NULL when
no driver is bound") the driver-data pointer is set to NULL by driver
core post unbind anyway.
For historical reasons, USB core also clears this pointer when an
explicitly claimed interface is released.
Due to a misunderstanding, a misleading kernel doc comment for
usb_set_intfdata() was recently added which claimed that the driver data
pointer must not be cleared during disconnect before "all actions [are]
completed", which is both imprecise and incorrect.
Specifically, drivers like cdc-acm which claim additional interfaces use
the driver-data pointer as a flag which is cleared when the first
interface is unbound. As long as a driver does not do something odd like
dereference the pointer in, for example, completion callbacks, this can
be done at any time during disconnect. And in any case this is no
different than for any other resource, like the driver data itself,
which may be freed by the disconnect callback.
Note that the comment actually also claimed that the interface itself
was somehow being set to NULL by driver core.
Fix the kernel doc by removing incorrect, overly specific and misleading
details and adding a comment about why some drivers do clear the
driver-data pointer.

Add a helper to evaluate ACPI usb device specific method (_DSM) provided
in case the USB3 port shouldn't enter U1 and U2 link states.
This _DSM was added as port specific retimer configuration may lead to
exit latencies growing beyond U1/U2 exit limits, and OS needs a way to
find which ports can't support U1/U2 link power management states.
This _DSM is also used by windows:

Pull ARM SoC DT and driver fixes from Arnd Bergmann:
"Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
including:
- A regression fix for SDHCI controllers on Inforce 6540, and another
SDHCI fix on SM8350
- Reenable cluster idle on sm8250 after the the code fix is upstream
- multiple fixes for the QMP PHY binding, needing an incompatible dt
change
- The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
6P, to avoid instabilities caused by use of protected memory
regions
- Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
clock error
- A couple of verdin-imx8mm DT fixes for audio playback support
- Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees
- Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
eMMC CMD8 CRC error in HS400ES/HS400 mode
The remaining ARM and RISC-V platforms only have very few smaller dts
bugfixes this time:
- A fix for the SiFive unmatched board's PCI memory space
- A revert to fix a regression with GPIO on Marvell Armada
- A fix for the UART address on Marvell AC5
- Missing chip-select phandles for stm32 boards
- Selecting the correct clock for the sam9x60 memory controller
- Amlogic based Odroid-HC4 needs a revert to restore USB
functionality.
And finally, there are some minor code fixes:
- Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
firmware
- memory controller driver fixes for an OMAP regression and older
bugs on tegra, atmel and mvebu
- reset controller fixes for ti-sci and uniphier platforms
- ARM SCMI firmware fixes for a couple of rare corner cases
- Qualcomm platform driver fixes for incorrect error handling and a
backwards compatibility fix for the apr driver using older dtb
- NXP i.MX SoC driver fixes for HDMI output, error handling in the
imx8 soc-id and missing reference counting on older cpuid code"

We silently cast an unsigned int into a __le32 which makes sparse
complain. Moreover, we never actually convert endianness between the
CPU's and the expected little-endian value. Fix both at once by calling
cpu_to_le32().

ARM: SoC fixes
These are three fixes for mistakes I discovered during the preparation
of the boardfile removal. Robert noticed the accidental removal
of PXA310 and PXA320 support because of a misplaced Kconfig statement,
and the two OMAP patches were build failures that got introduced
earlier but that I found while testing the removal.

While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like
ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':
drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority'
ld: drivers/dma/ti/omap-dma.o: in function `omap_dma_free_chan_resources':
drivers/dma/ti/omap-dma.c:777: undefined reference to `omap_free_dma'
drivers/dma/ti/omap-dma.c:1685: undefined reference to `omap_get_plat_info'
ld: drivers/usb/gadget/udc/omap_udc.o: in function `next_in_dma':
drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status'
I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like
arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]
As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

It was determined that the do_idr_lock parameter to
bpf_prog_free_id() was not necessary as it should always be true.

syzbot reported a nasty crash [1] in net_tx_action() which
made little sense until we got a repro.
This repro installs a taprio qdisc, but providing an
invalid TCA_RATE attribute.
qdisc_create() has to destroy the just initialized
taprio qdisc, and taprio_destroy() is called.
However, the hrtimer used by taprio had already fired,
therefore advance_sched() called __netif_schedule().
Then net_tx_action was trying to use a destroyed qdisc.
We can not undo the __netif_schedule(), so we must wait
until one cpu serviced the qdisc before we can proceed.
Many thanks to Alexander Potapenko for his help.

When a running wake_tx_queue() call is aborted due to a hw queue stop
the corresponding iTXQ is not always correctly marked for resumption:
wake_tx_push_queue() can stops the queue run without setting
@IEEE80211_TXQ_STOP_NETIF_TX.
Without the @IEEE80211_TXQ_STOP_NETIF_TX flag __ieee80211_wake_txqs()
will not schedule a new queue run and remaining frames in the queue get
stuck till another frame is queued to it.
Fix the issue for all drivers - also the ones with custom wake_tx_queue
callbacks - by moving the logic into ieee80211_tx_dequeue() and drop the
redundant @txqs_stopped.
@IEEE80211_TXQ_STOP_NETIF_TX is also renamed to @IEEE80211_TXQ_DIRTY to
better describe the flag.

The rename from mm->mmap_sem to mm->mmap_lock was performed in commit
da1c55f1b272 ("mmap locking API: rename mmap_sem to mmap_lock") and commit
c1e8d7c6a7a6 ("map locking API: convert mmap_sem comments"), however some
incorrect comments remain.
This patch simply corrects those comments which are obviously incorrect
within mm itself.

Commit 449c796768c9 ("mm: teach release_pages() to take an array of
encoded page pointers too") added the kernel doc comment for
release_pages() on top of 'union release_pages_arg', so making 'make
htmldocs' complains as below:
./include/linux/mm.h:1268: warning: cannot understand function prototype: 'typedef union '
The kernel doc comment for the function is already on top of the
function's definition in mm/swap.c, and the new comment is actually not
for the function but indeed release_pages_arg. Fixing the comment to
reflect the intent would be one option. But, kernel doc cannot parse
the union as below due to the attribute.
./include/linux/mm.h:1272: error: Cannot parse struct or union!
Modify the comment to reflect the intent but do not mark it as a kernel
doc comment.

free_anon_vma_name() is missing a check for anonymous shmem VMA which
leads to a memory leak due to refcount not being dropped. Fix this by
calling anon_vma_name_put() unconditionally. It will free vma->anon_name
whenever it's non-NULL.

Nathan reports that recent kernels built with LTO will crash when doing
EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a
misaligned load from the TPM event log, which is annotated with
READ_ONCE(), and under LTO, this gets translated into a LDAR instruction
which does not tolerate misaligned accesses.
Interestingly, this does not happen when booting the same kernel
straight from the UEFI shell, and so the fact that the event log may
appear misaligned in memory may be caused by a bug in GRUB or SHIM.
However, using READ_ONCE() to access firmware tables is slightly unusual
in any case, and here, we only need to ensure that 'event' is not
dereferenced again after it gets unmapped, but this is already taken
care of by the implicit barrier() semantics of the early_memunmap()
call.

The Dell Latitude E6430 both with and without the optional NVidia dGPU
has a bug in its ACPI tables which is causing Linux to assign the wrong
ACPI fwnode / companion to the pci_device for the i915 iGPU.
Specifically under the PCI root bridge there are these 2 ACPI Device()s :
Scope (_SB.PCI0)
{
Device (GFX0)
{
Name (_ADR, 0x00020000) // _ADR: Address
}
...
Device (VID)
{
Name (_ADR, 0x00020000) // _ADR: Address
...
Method (_DOS, 1, NotSerialized) // _DOS: Disable Output Switching
{
VDP8 = Arg0
VDP1 (One, VDP8)
}
Method (_DOD, 0, NotSerialized) // _DOD: Display Output Devices
{
...
}
...
}
}
The non-functional GFX0 ACPI device is a problem, because this gets
returned as ACPI companion-device by acpi_find_child_device() for the iGPU.
This is a long standing problem and the i915 driver does use the ACPI
companion for some things, but works fine without it.
However since commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()")
acpi_get_pci_dev() relies on the physical-node pointer in the acpi_device
and that is set on the wrong acpi_device because of the wrong
acpi_find_child_device() return. This breaks the ACPI video code,
leading to non working backlight control in some cases.
Add a type.backlight flag, mark ACPI video bus devices with this and make
find_child_checks() return a higher score for children with this flag set,
so that it picks the right companion-device.

Pull arm64 fixes from Will Deacon:
"Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What
could possibly go wrong?
The obvious reason we have so much here is because of the holiday
season right after the merge window, but we've also brought back an
erratum workaround that was previously dropped at the last minute and
there's an MTE coredumping fix that strays outside of the arch/arm64
directory.
Summary:
- Fix PAGE_TABLE_CHECK failures on hugepage splitting path
- Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header
- Fix NULL deref when accessing debugfs node if PSCI is not present
- Fix MTE core dumping when VMA list is being updated concurrently
- Fix SME signal frame handling when SVE is not implemented by the
CPU
- Fix asm constraints for cmpxchg_double() to hazard both words
- Fix build failure with stack tracer and older versions of Clang
- Bring back workaround for Cortex-A715 erratum 2645198"
