This commit adds a new flag, devmem_only, to the drm_gpusvm structure. The
purpose of this flag is to ensure that the get_pages function allocates
memory exclusively from the device's memory. If the allocation from
device memory fails, the function will return an -EFAULT error.
Required for shared CPU and GPU atomics on certain devices.
v3:
- s/vram_only/devmem_only/

On VCN v4.0.5 there is a race condition where the WPTR is not
updated after starting from idle when doorbell is used. Adding
register read-back after written at function end is to ensure
all register writes are done before they can be used.

software cursor"
This reverts commit 272e6aab14bbf98d7a06b2b1cd6308a02d4a10a1.
Applying degamma curve to the cursor by default breaks Linux userspace
expectation.
On Linux, AMD display manager enables cursor degamma ROM just for
implict sRGB on HW versions where degamma is split into two blocks:
degamma ROM for pre-defined TFs and `gamma correction` for user/custom
curves, and degamma ROM settings doesn't apply to cursor plane.

When executing the "perf probe" and "perf stat" test cases about some
cryptographic algorithm, the output shows that "Trace/breakpoint trap".
This is because it uses the software singlestep breakpoint for uprobes
on LoongArch, and no need to use the hardware singlestep. So just remove
the related function call to user_{en,dis}able_single_step() for uprobes
on LoongArch.
How to reproduce:
Please make sure CONFIG_UPROBE_EVENTS is set and openssl supports sm2
algorithm, then execute the following command.
cd tools/perf && make
./perf probe -x /usr/lib64/libcrypto.so BN_mod_mul_montgomery
./perf stat -e probe_libcrypto:BN_mod_mul_montgomery openssl speed sm2

Save and restore CSR.CNTC for hibernation which is similar to suspend.
For host this is unnecessary because sched clock is ensured continuous,
but for kvm guest sched clock isn't enough because rdtime.d should also
be continuous.
Host::rdtime.d = Host::CSR.CNTC + counter
Guest::rdtime.d = Host::CSR.CNTC + Host::CSR.GCNTC + Guest::CSR.CNTC + counter
so,
Guest::rdtime.d = Host::rdtime.d + Host::CSR.GCNTC + Guest::CSR.CNTC
To ensure Guest::rdtime.d continuous, Host::rdtime.d should be at first
continuous, while Host::CSR.GCNTC / Guest::CSR.CNTC is maintained by KVM.

When CONFIG_PREEMPT_COUNT is not configured (i.e. CONFIG_PREEMPT_NONE/
CONFIG_PREEMPT_VOLUNTARY), preempt_disable() / preempt_enable() merely
acts as a barrier(). However, in these cases cond_resched() can still
trigger a context switch and modify the CSR.EUEN, resulting in do_fpu()
exception being activated within the kernel-fpu critical sections, as
demonstrated in the following path:
dcn32_calculate_wm_and_dlg()
DC_FP_START()
dcn32_calculate_wm_and_dlg_fpu()
dcn32_find_dummy_latency_index_for_fw_based_mclk_switch()
dcn32_internal_validate_bw()
dcn32_enable_phantom_stream()
dc_create_stream_for_sink()
kzalloc(GFP_KERNEL)
__kmem_cache_alloc_node()
__cond_resched()
DC_FP_END()
This patch is similar to commit d02198550423a0b (x86/fpu: Improve crypto
performance by making kernel-mode FPU reliably usable in softirqs). It
uses local_bh_disable() instead of preempt_disable() for non-RT kernels
so it can avoid the cond_resched() issue, and also extend the kernel-fpu
application scenarios to the softirq context.

Fix a potential deadlock bug. Observe that in the mtk-cqdma.c
file, functions like mtk_cqdma_issue_pending() and
mtk_cqdma_free_active_desc() properly acquire the pc lock before the vc
lock when handling pc and vc fields. However, mtk_cqdma_tx_status()
violates this order by first acquiring the vc lock before invoking
mtk_cqdma_find_active_desc(), which subsequently takes the pc lock. This
reversed locking sequence (vc → pc) contradicts the established
pc → vc order and creates deadlock risks.
Fix the issue by moving the vc lock acquisition code from
mtk_cqdma_find_active_desc() to mtk_cqdma_tx_status(). Ensure the pc lock
is acquired before the vc lock in the calling function to maintain correct
locking hierarchy. Note that since mtk_cqdma_find_active_desc() is a
static function with only one caller (mtk_cqdma_tx_status()), this
modification safely eliminates the deadlock possibility without affecting
other components.
This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs to extract
function pairs that can be concurrently executed, and then analyzes the
instructions in the paired functions to identify possible concurrency bugs
including deadlocks, data races and atomicity violations.

Bug: When we compile the kernel with CONFIG_XFS_SUPPORT_V4=y,
remount with "-o remount,noattr2" on a v5 XFS does not
fail explicitly.
Reproduction:
mkfs.xfs -f /dev/loop0
mount /dev/loop0 /mnt/scratch
mount -o remount,noattr2 /dev/loop0 /mnt/scratch
However, with CONFIG_XFS_SUPPORT_V4=n, the remount
correctly fails explicitly. This is because the way the
following 2 functions are defined:
static inline bool xfs_has_attr2 (struct xfs_mount *mp)
{
return !IS_ENABLED(CONFIG_XFS_SUPPORT_V4) ||
(mp->m_features & XFS_FEAT_ATTR2);
}
static inline bool xfs_has_noattr2 (const struct xfs_mount *mp)
{
return mp->m_features & XFS_FEAT_NOATTR2;
}
xfs_has_attr2() returns true when CONFIG_XFS_SUPPORT_V4=n
and hence, the following if condition in
xfs_fs_validate_params() succeeds and returns -EINVAL:
/*
* We have not read the superblock at this point, so only the attr2
* mount option can set the attr2 feature by this stage.
*/
if (xfs_has_attr2(mp) && xfs_has_noattr2(mp)) {
xfs_warn(mp, "attr2 and noattr2 cannot both be specified.");
return -EINVAL;
}
With CONFIG_XFS_SUPPORT_V4=y, xfs_has_attr2() always return
false and hence no error is returned.
Fix: Check if the existing mount has crc enabled(i.e, of
type v5 and has attr2 enabled) and the
remount has noattr2, if yes, return -EINVAL.
I have tested xfs/{189,539} in fstests with v4
and v5 XFS with both CONFIG_XFS_SUPPORT_V4=y/n and
they both behave as expected.
This patch also fixes remount from noattr2 -> attr2 (on a v4 xfs).

xfs_zone_gc_write_chunk writes out the data buffer read in earlier using
the same bio, and currenly looks at bv_offset for the offset into the
scratch folio for that. But commit 26064d3e2b4d ("block: fix adding
folio to bio") changed how bv_page and bv_offset are calculated for
adding larger folios, breaking this fragile logic.
Switch to extracting the full physical address from the old bio_vec,
and calculate the offset into the folio from that instead.
This fixes data corruption during garbage collection with heavy rockdsb
workloads. Thanks to Hans for tracking down the culprit commit during
long bisection sessions.

Not everything requires locking in there, which is why the 'has_lock'
variable exists. But enough does that it's a bit unwieldy to manage.
Wrap the whole thing in a ->uring_lock trylock, and just return
with no output if we fail to grab it. The existing trylock() will
already have greatly diminished utility/output for the failure case.
This fixes an issue with reading the SQE fields, if the ring is being
actively resized at the same time.

If device_add() fails, do not use device_unregister() for error
handling. device_unregister() consists two functions: device_del() and
put_device(). device_unregister() should only be called after
device_add() succeeded because device_del() undoes what device_add()
does if successful. Change device_unregister() to put_device() call
before returning from the function.
As comment of device_add() says, 'if device_add() succeeds, you should
call device_del() when you want to get rid of it. If device_add() has
not succeeded, use only put_device() to drop the reference count'.

The phy-rcar-gen3-usb2 driver exposes four individual PHYs that are
requested and configured by PHY users. The struct phy_ops APIs access the
same set of registers to configure all PHYs. Additionally, PHY settings can
be modified through sysfs or an IRQ handler. While some struct phy_ops APIs
are protected by a driver-wide mutex, others rely on individual
PHY-specific mutexes.
This approach can lead to various issues, including:
1/ the IRQ handler may interrupt PHY settings in progress, racing with
hardware configuration protected by a mutex lock
2/ due to msleep(20) in rcar_gen3_init_otg(), while a configuration thread
suspends to wait for the delay, another thread may try to configure
another PHY (with phy_init() + phy_power_on()); re-running the
phy_init() goes to the exact same configuration code, re-running the
same hardware configuration on the same set of registers (and bits)
which might impact the result of the msleep for the 1st configuring
thread
3/ sysfs can configure the hardware (though role_store()) and it can
still race with the phy_init()/phy_power_on() APIs calling into the
drivers struct phy_ops
To address these issues, add a spinlock to protect hardware register access
and driver private data structures (e.g., calls to
rcar_gen3_is_any_rphy_initialized()). Checking driver-specific data remains
necessary as all PHY instances share common settings. With this change,
the existing mutex protection is removed and the cleanup.h helpers are
used.
While at it, to keep the code simpler, do not skip
regulator_enable()/regulator_disable() APIs in
rcar_gen3_phy_usb2_power_on()/rcar_gen3_phy_usb2_power_off() as the
regulators enable/disable operations are reference counted anyway.

Commit 08b0ad375ca6 ("phy: renesas: rcar-gen3-usb2: move IRQ registration
to init") moved the IRQ request operation from probe to
struct phy_ops::phy_init API to avoid triggering interrupts (which lead to
register accesses) while the PHY clocks (enabled through runtime PM APIs)
are not active. If this happens, it results in a synchronous abort.
One way to reproduce this issue is by enabling CONFIG_DEBUG_SHIRQ, which
calls free_irq() on driver removal.
Move the IRQ request and free operations back to probe, and take the
runtime PM state into account in IRQ handler. This commit is preparatory
for the subsequent fixes in this series.

It has been observed on the Renesas RZ/G3S SoC that unbinding and binding
the PHY driver leads to role autodetection failures. This issue occurs when
PHY 3 is the first initialized PHY. PHY 3 does not have an interrupt
associated with the USB2_INT_ENABLE register (as
rcar_gen3_int_enable[3] = 0). As a result, rcar_gen3_init_otg() is called
to initialize OTG without enabling PHY interrupts.
To resolve this, add rcar_gen3_is_any_otg_rphy_initialized() and call it in
role_store(), role_show(), and rcar_gen3_init_otg(). At the same time,
rcar_gen3_init_otg() is only called when initialization for a PHY with
interrupt bits is in progress. As a result, the
struct rcar_gen3_phy::otg_initialized is no longer needed.

max20086_parse_regulators_dt() calls of_regulator_match() using an
array of struct of_regulator_match allocated on the stack for the
matches argument.
of_regulator_match() calls devm_of_regulator_put_matches(), which calls
devres_alloc() to allocate a struct devm_of_regulator_matches which will
be de-allocated using devm_of_regulator_put_matches().
struct devm_of_regulator_matches is populated with the stack allocated
matches array.
If the device fails to probe, devm_of_regulator_put_matches() will be
called and will try to call of_node_put() on that stack pointer,
generating the following dmesg entries:
max20086 6-0028: Failed to read DEVICE_ID reg: -121
kobject: '\xc0$\xa5\x03' (000000002cebcb7a): is not initialized, yet
kobject_put() is being called.
Followed by a stack trace matching the call flow described above.
Switch to allocating the matches array using devm_kcalloc() to
avoid accessing the stack pointer long after it's out of scope.
This also has the advantage of allowing multiple max20086 to probe
without overriding the data stored inside the global of_regulator_match.

The SPI interface is activated before the CPOL setting is applied. In
that moment, the clock idles high and CS goes low. After a short delay,
CPOL and other settings are applied, which may cause the clock to change
state and idle low. This transition is not part of a clock cycle, and it
can confuse the receiving device.
To prevent this unexpected transition, activate the interface while CPOL
and the other settings are being applied.

A change to QEMU resulted in all nvme controllers (single and
multi-controller subsystems) to have its CMIC.MCTRS bit set which
indicates the subsystem supports multiple controllers and it is possible
a namespace can be shared between those multiple controllers in a
multipath configuration.
When a namespace of a CMIC.MCTRS enabled subsystem is allocated, a
multipath node is created. The queue limits for this node are inherited
from the namespace being allocated. When inheriting queue limits, the
features being inherited need to be specified. The atomic write feature
(BLK_FEAT_ATOMIC_WRITES) was not specified so the atomic queue limits
were not inherited by the multipath disk node which resulted in the sysfs
atomic write attributes being zeroed. The fix is to include
BLK_FEAT_ATOMIC_WRITES in the list of features to be inherited.

MACsec offload feature must be cleared from the netdevice's features.
If left enabled, attempts to add offloads result in a null pointer
dereference, as the uplink representor does not support MACsec offload
even though the feature bit remains set.
