Pull TPM updates from Jarkko Sakkinen:
"The bulk of this is Ross Philipson's TPM enablement for Trenchboot.
That exposes TPM constants, and decouple and improve robustness of
tpm_buf a bit in order to implement a minimal early TPM driver.
Early boot code will call either SKINIT on AMD or GETSEC[SENTER] on
Intel before jumping into kernel's entry point. They re-initalize TPM
PCRs but leave up to the early boot code measure initrd, boot_params
and Trenchboot associated metadata.
The motivation here is just that we would want in future iterations of
the series put our full focus to the x86 part of the review, and call
it a day as per TPM changes. Further, even if Trenchboot turned out to
be empty lottery the worst possible outcome for TPM driver is that
things get cleaned up a bit"

ATM device ci_range fields (vpi_bits and vci_bits) represent the
number of bits supported for VPI and VCI addressing on the device.
net/atm/common.c directly uses these fields as bit shift counts:
vpi >> dev->ci_range.vpi_bits
vci >> dev->ci_range.vci_bits
1 << vcc->dev->ci_range.vpi_bits
1 << vcc->dev->ci_range.vci_bits
usbatm_atm_init() sets ci_range.vpi_bits and ci_range.vci_bits to
ATM_CI_MAX (-1), which is defined in <uapi/linux/atmdev.h> as a
sentinel value for userspace ATM_SETCIRANGE requests, not a valid bit
count. Shifting by -1 is undefined behavior and triggers UBSAN
warnings.
ATM UNI cell headers allow up to 8 bits for VPI (0..255) and 16 bits
for VCI (0..65535). Initialize vpi_bits to 8 and vci_bits to 16, as
done by solos-pci.

fec_ptp_init() is only called when fep->bufdesc_ex is available.
However, fec_probe() unconditionally calls fec_ptp_stop() on the
failed_init path, and fec_drv_remove() unconditionally calls
fec_ptp_stop() during device removal.
Check fep->bufdesc_ex before calling fec_ptp_stop() in both paths
to avoid stopping PTP when it was not initialized.

Jaeyoung Chung and Eulgyu Kim reported a slab-use-after-free read
in slip_receive_buf() when racing against tty hangup.
tty_ldisc_hangup() calls ld->ops->hangup() while holding only
a read lock on tty->ldisc_sem (via tty_ldisc_ref()).
Because slip_hangup() simply called slip_close(), it ran concurrently
with reader functions such as slip_receive_buf().
slip_close() unregisters and frees the net device and its private
struct slip, causing concurrent reader threads in slip_receive_buf()
to dereference freed memory.
Line discipline close() is already guaranteed to be called under
the write lock of tty->ldisc_sem during hangup processing
(in tty_ldisc_reinit() or tty_ldisc_kill()).
Remove slip_hangup() so teardown is serialized cleanly by slip_close().
Fixes: 5342b77c4123 ("slip: Clean up create and destroy")

The MxL862xx driver enables FDB isolation but does not enable assisted
learning on the CPU port. Consequently, MAC addresses learned through a
physical switch port are not updated in hardware when the corresponding
station moves to a foreign bridge port, such as a Wi-Fi interface.
The stale hardware FDB entry continues directing return traffic toward
the original physical port. Traffic entering that same port is then
filtered instead of being forwarded to the CPU and software bridge. This
causes downstream unicast traffic, including DHCP OFFER and ACK packets,
to disappear after a client roams to a local wireless interface. The
client eventually considers the connection unusable and disconnects.
Enable assisted CPU-port learning so DSA installs foreign bridge FDB
entries on the CPU port. This keeps the hardware FDB synchronized with
the software bridge and allows return traffic to reach locally attached
Wi-Fi clients after roaming.
Tested on a BPI R4 PRO with a MxL862xx switch and a BE14000 WiFi interface.
- Without patch, wired uplink on lan6 port (mxl path)
Wifi clients connect but roam away not getting DHCP offers
- Without patch, wired uplink on wan port (no mxl path)
Wifi clients connect and roam successfully
- With this patch, uplink on lan6 (mxl path)
Wifi clients connect and roam successfully

Since the RX path was converted to zero-copy, the page pool page is handed
to the stack directly as the skb head, and the offset the DMA engine writes
at is what determines the alignment of the packet headers.
Before the conversion the payload was copied into an skb obtained from
napi_alloc_skb(), which reserves NET_SKB_PAD + NET_IP_ALIGN. The
conversion moved the headroom into stmmac_rx_offset() but did not carry
over NET_IP_ALIGN, so on architectures where NET_IP_ALIGN is 2 the IP
header now lands misaligned:
64 (NET_SKB_PAD) + 14 (ethernet) + 20 (IP) = 98
Same for the XDP branch:
256 (XDP_PACKET_HEADROOM) + 14 (ethernet) + 20 (IP) = 290
On ARM32 this is fatal, because ldm and ldrd trap on unaligned addresses
even when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set.
Any received echo request panics the machine, e.g:
Unhandled fault: alignment exception (0x001) at 0x81873062

Kernel panic - not syncing: Fatal exception in interrupt
The faulting instruction is the ldm of *icmp_hdr(skb) in icmp_echo().
Fix by adding NET_IP_ALIGN back to the RX offset, which restores the
alignment the stack used to get.
Note that commit a955318fe67e ("stmmac: align RX buffers") made a similar
change in 2021 and was reverted by commit 12d125b4574b ("stmmac: Revert
"stmmac: align RX buffers"") because it caused packet corruption. That
patch raised the offset from 0 without adjusting the buffer size
accounting, so the DMA engine could arguably write past the end of the RX
buffers, though this was never root caused.
Commit df542f669307 ("net: stmmac: Switch to zero-copy in non-XDP RX
path") since derives the page pool allocation from stmmac_rx_offset(), so
the extra bytes are accounted for.

The gso_enabled_types field is used by stmmac_xmit() to decide whether a
GSO skb should be passed to stmmac_tso_xmit(). It is updated in
stmmac_set_features() based solely on NETIF_F_TSO, so disabling IPv4
TSO while keeping IPv6 TSO (NETIF_F_TSO6) enabled zeroes the mask. As a
result IPv6 GSO frames, which the networking stack still generates since
NETIF_F_TSO6 is enabled, fall through to the non-TSO xmit path where
they are not handled.
The networking stack already manages the GSO logic: a GSO skb is only
delivered to the driver when the matching offload feature (NETIF_F_TSO,
NETIF_F_TSO6 or NETIF_F_GSO_UDP_L4) is enabled, otherwise the frame is
segmented in software before reaching ndo_start_xmit().
stmmac_features_check() also validates each GSO frame against the TSO
hardware constraints and falls back to software GSO when they are not met.
Drop the gso_enabled_types field and rely on skb_is_gso() in
stmmac_xmit() instead, which correctly routes IPv6 GSO frames to the TSO
path when NETIF_F_TSO is disabled. This also removes the data race
between stmmac_set_gso_types(), called from the feature-set path, and
the lockless read of gso_enabled_types in stmmac_xmit().

On dwmac1000, dwmac4 and dwxgmac, we only emit pause frames if there's
at least 4096 bytes in each queue's fifo.
The phylink mac capabilities are still MAC_ASYM_PAUSE | MAC_SYM_PAUSE as
otherwise we won't be able to negotiate 'rx on' pause. ASYM only will
prevent negotiating 'rx off tx on', while SYM only doesn't really
matche the reality (not symmetric if we can only do RX pause).

On dwmac, one of the Unicast filter entries is used to store the local
HW addr. This means that we have to use promisc mode for any kind of
unicast filtering if we only have one slot in our unicast filter.
The number of slots available depends on how the IP is integrated, and
we can't autodiscover how many of these slots we have available, so
the DT property snps,perfect-filter-entries can be used to specify how
many are available.
Most IP variants default to 1 if this isn't specified, which is the case
for the amlogic variants (in this case, S905X3).
The stmmac selftests for UC filtering look if we have enough slots in
the filter to store the dev->uc list, but doesn't account for the
device's own MAC address. The dev->uc list's size we get with
netdev_uc_count() also doesn't account for the HW addr.
As the selftest only requires one available slot, in the case of
single-slot platforms, that means we erroneously consider we have enough
room for the test, when we actually don't, and the filtering test fails.

The MMC counters report MAC statistics. Multiple counters can be
enabled when the IP is integrated, however there's no way to know
exactly which ones. Un-implemented counters seem to report 0.
It was found that on StarFive JH7110 and Amlogic SM1, the counter that's
used by the selftest (mmc_tx_framecount_g) isn't implemented, triggering
an MMC selftest failure.
Both the above SoCs seem to implement mmc_rx_framecount_gb, let's use
this counter as well for MMC counter validation.
Note that this doesn't guarantee that we won't encounter the same issue
again if another IP implements yet another set of counters that don't
include that new one.
If the game of whack-a-mole with implemented counters becomes too hard to
maintain, we may simply consider removing the MMC selftest entirely.

to resolve confusion around reverse mapping for zeroed and CoW'd
file-backed memory.
Use this new VMA anonymous page offset tracking to eliminate index
conflicts and lay the foundation for scalable CoW performance
improvements.

executable file folios after their first usage to give executable
code a better chance to stay in memory and improve workload
performance.
- "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong
Chen)
Fix per-node proactive reclaim interface's ignoring the swappiness
parameter when CONFIG_MEMCG is disabled by consolidating
sc_swappiness() into a single function that checks
proactive_swappiness regardless of kernel configuration.
- "mm/vmscan: reduce lru_lock contention via vmstat-derived
scan-balance cost" (Usama Arif)
Reduce lru_lock contention in the reclaim path by deriving
scan-balance costs from vmstat counters rather than lock-acquired
producer updates.
Read and decay these cost signals on the reclaim side under a
dedicated per-lruvec lock, reducing total LRU lock wait time by over
60% without impacting scan throughput.
- "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky)
Fix two low-risk zram bugs which Sashiko spotted in drive-by review.
- "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's

Fix xas_split_alloc() by enabling target folio memcg charging during
splits and adding the missing __GFP_ACCOUNT flag for proper XArray
node memory accounting.
- "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick)
Replace hardcoded binary names in selftests/mm/.gitignore with a
generic pattern-matching rule to automatically ignore generated test
files and avoid manual updates when adding new tests.
- "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon)
Make the incompatibility between FLATMEM and NUMA explicit in
mm/Kconfig and remove the unused pgdat_page_ext_init() function.
- "zram: fix zstd error paths and add parameter validation" (Haoqin
Huang)
Clean up zram compression backends by removing redundant error
cleanup, adding parameter and dictionary validation, auto-prefixing
algorithm error logs, and resetting parameters prior to
reinitialization.
- "zram: fix stale scan bounds after reinitialization" (Longlong Xia)
Prevent out-of-bounds slot accesses during concurrent zram resets by
moving table scan bound calculations under dev_lock in
writeback_store() and read_block_state().
- "add anon mTHP collapse test cases" (Baolin Wang)
Extend selftests helper functions to support arbitrary page orders
and add new test cases and options for mTHP collapse in khugepaged.
- "selftests/mm: Handle unsupported and transient test conditions"
(Muhammad Usama Anjum)
Update MM selftests to report a SKIP status instead of a failure when
required kernel or filesystem features are unsupported, while adding
retry logic for transient page migration errors.
- "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia)
Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled
and extend shrink_memcg() to support batch writeback for improved
writeback efficiency.
- "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren
Baghdasaryan)
Introduce an IOCTL-based binary interface for memory allocation
profiling that enables kernel-side filtering before per-CPU counter
aggregation.
This eliminates the text-parsing overhead of /proc/allocinfo and
provides up to a 20x speedup by transferring only filtered allocation
data to userspace.
- "better block swap batching and a different take on swap_ops v5"
(Christoph Hellwig)
Refactor block swap I/O to use swap_iocb for batching instead of
single-bio requests and rebase the swap_ops interface, achieving
faster swap throughput during kernel builds.
- "mm: kmemleak: reduce transient false positives by confirming leaks"
(Catalin Marinas)
Reduce false-positive kmemleak reports by combining two kmemleak
enhancements that add a second confirmation scan and a configurable
minimum unreferenced scan count module parameter.
- "mm: kmemleak: default min_unref_scans to 2 for verbose kernels"
(Breno Leitao)
Auto-scanning kernels can generate false-positive memory leak reports
on single scans, so this patch defaults min_unref_scans to 2 when
CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second
confirming scan.
- "swap_ops updates" (Christoph Hellwig)
Batching I/O for synchronous swap devices causes performance
regressions and filesystem-based swap suffers from double-indirection
overhead. This series resolves both issues by reintroducing per-folio
writes for synchronous swap and allowing filesystems to directly
export their own swap_ops.
- "mm/khugepaged: several cleanups" (Nico Pache)
khugepaged accumulated redundant state-checking patterns and outdated
comments following mTHP integration. Introduce dedicated helpers for
PTE validation and event counting while refreshing the internal
documentation.
- "maple_tree: lock checking and clean ups" (Liam Howlett)
Syzbot reports incorrectly blame memory management exit paths for
locking bugs, maple tree erase operations risk allocation failures
without gfp flags and internal documentation lacks clarity.
Improve lock error detection, update docs, fix race and allocation
edge cases and optimize erase allocations using a fallback to
GFP_KERNEL | GFP_NOFAIL.

The mailbox PHASE bit in SYSCTRL_MB_CTRL is toggled per-message and
was tracked in software as sc->phase_bit, reset to 0 on error paths.
If the cached value ever drifts from what the hardware last saw, all
following messages carry the wrong phase and get silently misread by
firmware.
Drop the cache and read PHASE directly from SYSCTRL_MB_CTRL before
each frame instead, removing xe_sysctrl_mailbox_init() and its call

Some platforms make an assumption that the i2c controller's
enabled state indicates also the power state of the
controller. This can create a problem when the controller is
in disabled state, because the hardware may assume
incorrectly that it is then also in low-power state.
To fix this, the controller is kept enabled by taking over
the IC_ENABLE register. The controller has to be disabled
when the configuration is updated and when the target
address or the slave address are assigned, so disabling it
when IC_CON, IC_TAR or IC_SAR registers are programmed, and
then re-enabling it again.

The platforms that support the interrupt from the I2C
adapter can not handle the amount of interrupts the adapter
generates because of the way the IRQ is routed in the
hardware. The I2C controller driver has to be kept in
polling mode because of that.
The AMC MCU can still generate critical alerts that have to
be handled. The interrupt from SMBus Alert is left enabled
and handled separately in the Xe. The alerts from the AMC
will cause the device to be declared wedged for now.

The driver calls dma_set_coherent_mask() but never dma_set_mask(),
leaving the streaming DMA mask at the bus default. On the non-coherent
EN7581 platform (Cortex-A53), this causes the NPU mailbox to hang
after approximately 41 calls when using streaming DMA mappings.
Replace dma_set_coherent_mask() with dma_set_mask_and_coherent() to
set both the streaming and coherent DMA masks, matching standard
driver practice.

Revert commit dc948f8b384a ("ACPI: scan: Defer device power
initialization") that is incomplete and may cause ACPI power
management of devices to fail.
The problem is that PCI devices are associated with the
corresponding ACPI device objects before acpi_bus_attach()
runs for them, so after commit dc948f8b384a, ACPI power
management will not be initialized for them before making
that association. Consequently, the reference counting of
ACPI power resources may not work as expected going forward
and power management issues may appear. If they appear, they
may be elusive and hard to diagnose.
While this is fixable, I am not sure if fixing it on top of
commit dc948f8b384a is the best way to go, so it is better to
revert that commit for now and revisit the whole thing in the
next cycle.

Having scratch enabled does not make a VM capable of handling recoverable
page faults. Allowing scratch VMs through the ASID lookup also admits
dma-fence mode VMs.
If such a VM faults on an already valid VMA, the handler reports success
without fixing the fault, causing the GPU to retry indefinitely.
Only allow fault-mode VMs through the ASID lookup. Fault-mode VMs using
scratch remain supported, while faults from 3D VMs are rejected.

slip_devs[] stores bare net_device pointers and takes no reference on
them. sl_sync() and sl_alloc() walk that table from slip_open() under
rtnl_lock(), while an entry is dropped by sl_free_netdev(), which
sl_setup() installs as dev->priv_destructor.
priv_destructor is called from netdev_run_todo(), which deliberately
runs with the RTNL semaphore released so that it can sleep while waiting
for the device refcount to drop:
/* Snapshot list, allow later requests */
list_replace_init(&net_todo_list, &list);
__rtnl_unlock();
...
if (dev->priv_destructor)
dev->priv_destructor(dev); /* slip_devs[i] = NULL */
if (dev->needs_free_netdev)
free_netdev(dev);
...
/* Free network device */
kobject_put(&dev->dev.kobj);
So rtnl_lock() does not serialise slip_open() against the teardown at
all. sl_sync() can load slip_devs[i] while the entry is still published
and dereference it after netdev_run_todo() has run the destructor and
released the device:
CPU0 (slip_open) CPU1 (slip_close)
unregister_netdev()
rtnl_unlock()
netdev_run_todo()
__rtnl_unlock()
rtnl_lock()
sl_sync()
dev = slip_devs[i]
priv_destructor(dev)
slip_devs[i] = NULL
kobject_put(&dev->dev.kobj)
/* dev is freed */
sl = netdev_priv(dev)
if (sl->tty || sl->leased) /* use-after-free */

Commit e58c19124189 ("slip: Fix use-after-free Read in slip_open") fixed
a different source of stale entries - a device left in slip_devs[] after
slip_open() freed it on the registration error path - and does not
address this race, which is why the report survives it.
Drop the entry from ndo_uninit instead. unregister_netdevice() calls
ndo_uninit under RTNL, before the device is queued to netdev_run_todo(),
so an entry that sl_sync() can still see while holding RTNL belongs to a
device that cannot be freed until RTNL is dropped. sl_free_netdev()
stays only for the slip_open() error path, where register_netdevice()
may have failed before ndo_init and ndo_uninit is then not called
either. Both running for the same device is harmless: they run under
the same RTNL section, so the slot cannot have been reused in between.
This also removes the second symptom of the missing exclusion: a
destructor running after sl_alloc() had already handed the slot out to
another channel used to clear a live entry, so sl_sync() stopped at that
NULL, sl_alloc() returned the same index again, and
register_netdevice() failed with -EEXIST because slN was still there.
Reproduced on x86_64 with several threads looping over
open("/dev/ptmx") + ioctl(TIOCSETD, N_SLIP) + close().

The macros TXGBE_INTR_MISC() and WX_INTR_Q() rely on the standard BIT()
macro to generate interrupt masks based on the queue vector index.
On 32-bit architectures, BIT() evaluates to a 32-bit `unsigned long`.
Since the number of queue vectors can be up to 63 on txgbe devices,
performing a left shift of 32 or more results in an integer overflow
and undefined behavior. This causes incorrect interrupt masking and
unmasking logic for both the queue and miscellaneous interrupts on
32-bit systems.
Fix this by replacing BIT() with BIT_ULL() in these macros. This
ensures that the bitwise shift is always performed safely on a 64-bit
`unsigned long long` type, regardless of the underlying architecture.

The LED GPIO pins (GPIO3/4/5, mapped to LED2/LED1/LED0) are only ever
configured as outputs once, in .probe(). But .config_init() restarts
the MD32 MCU via en8811h_restart_mcu() on every call after the first
(priv->mcu_needs_restart), and that restart resets buckpbus-mapped MCU
state, including EN8811H_GPIO_OUTPUT. As a result the LED GPIOs fall
back to inputs after the first event that re-triggers .config_init()
(link renegotiation, ifdown/ifup, resume), and the PHY's LEDs stop
reflecting link/activity state even though they worked right after
probe.
Move the GPIO-as-output configuration from .probe() to the end of
.config_init(), so it is reapplied every time the MCU may have been
restarted.

When the driver is handed a burst of packets, the doorbell is deferred
until the end. If the last packet has a huge number of frags, but fails
to linearize, the doorbell will not be written adding latency on TX for
any packets in the ring and holding their DMA mappings until the next
TX. Note that the queue is not stopped, so this issue would delay
pending BDs until the next TX.
This issue was discovered by Sashiko and reading the code verifies that,
while unlikely, it is possible.
Fix this by jumping to tx_free, which replicates the same pre-existing
logic but also writes the doorbell.

Pull clk updates from Stephen Boyd:
"Mostly the usual clk driver updates and new SoC additions plus
non-critical data fixes for things that weren't used yet.
One thing that's new here in the core is SSC spread spectrum support
(SSC) in the clk provider API. The idea is that DT authors will
configure SSC for certain clks and they'll be configured at clk
provider registration time or when a consumer device is probed,
similar to how we handle assigned clk rates or parents.
On the clk driver side we have Qualcomm adding almost half the diff
because they add support for 4 different SoCs and then a long tail of
other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more
SoC support this time around. Luckily it's mostly clk data for these
new SoCs because the actual clk_ops are already there. Beyond the new
drivers we get all the little fixups for more compilation coverage or
usage of more modern APIs. That all looks normal.
Finally, I kinda buried the lede, I'm bringing on Brian and Jerome to
help out with maintaining the clk subsystem. The current working model
is already semi-distributed in that silicon vendors typically take
care of their drivers and send me pull requests but I'm becoming a
bottleneck for new drivers and core framework review because this has
become a 100% volunteer effort on my part.
Mike is stepping down after all these years (thanks Mike!) and that
jump started the conversation around finding co-maintainers. Brian and
Jerome have graciously offered to help me with the work load, meaning
in the future they'll be sending pull requests and committing directly
to the clk.git tree. They've both been around on the list for a while,
I've met them both in person, and they've been making changes to the
core clk framework along with helping review patches so I'm pretty
confident this will work well.
Core:
- devm_clk_bulk_get_enable() consumer API
- devm_clk_hw_register_composite_pdata() provider API

Merge additional cpufreq updates and one update related to system sleep
for 7.3-rc1:
- Unblock runtime PM when device prepare fails that was not done by
mistake (Shibo Zhu)
- Fix possible rate limit overflow on 32-bit systems in the schedutil
cpufreq governor (Hui Su)
- Consolidate HWP P-states initialization in the intel_pstate cpufreq
driver and make that driver avoid using the DESIRED_PERF HWP hint
when the Dynamic Efficiency Control (DEC) is enabled in the processor
to avoid inconsistent behavior (Rafael Wysocki)
* pm-cpufreq:
cpufreq: intel_pstate: Avoid using DESIRED_PERF when DEC is enabled
cpufreq: intel_pstate: Consolidate HWP P-states initialization
cpufreq: schedutil: Fix rate limit overflow
* pm-sleep:

Merge updates of assorted ACPI drivers for 7.3-rc1:
- Protect all battery properties with a separated mutex in the ACPI
battery driver to prevent race conditions from occurring and avoid
evaluating the _BST ACPI control method multiple times in parallel
for the same battery device (Rong Zhang)
- Add DMI quirk for Razer Blade Pro 17 early 2020 lid switch to the
ACPI button driver (Robin Everaars)
- Convert fixed clock rates in the ACPI driver for AMD SoCs (APD) to
use HZ_PER_MHZ and add a clock frequency for the HJMC01 I2C
controller to it (Hongnan Li and Xiangyang Yu)
- Fix a stack buffer overflow in query_capability() in the ACPI
platform firmware runtime update driver (Anirudh Prasad)
* acpi-battery:
ACPI: battery: Protect all properties with a separated mutex
* acpi-button:
ACPI: button: Add DMI quirk for Razer Blade Pro 17 early 2020 lid switch
