clk: samsung: Revert "clk: Use device_get_match_data()"

device_get_match_data() function should not be used on the device other
than the one matched to the given driver, because it always returns the
match_data of the matched driver. In case of exynos-clkout driver, the
original code matches the OF IDs on the PARENT device, so replacing it
with of_device_get_match_data() broke the driver.

This has been already pointed once in commit 2bc5febd05ab ("clk: samsung:
Revert "clk: samsung: exynos-clkout: Use of_device_get_match_data()"").
To avoid further confusion, add a comment about this special case, which
requires direct of_match_device() call to pass custom IDs array.

This partially reverts commit 409c39ec92a35e3708f5b5798c78eae78512cd71.

usb: typec: tcpm: enforce ready state when queueing alt mode vdm

Before sending Enter Mode for an Alt Mode, there is a gap between Discover
Modes and the Alt Mode driver queueing the Enter Mode VDM for the port
partner to send a message to the port.

If this message results in unregistering Alt Modes such as in a DR_SWAP,
then the following deadlock can occur with respect to the DisplayPort Alt
Mode driver:
1. The DR_SWAP state holds port->lock. Unregistering the Alt Mode driver
results in a cancel_work_sync() that waits for the current dp_altmode_work
to finish.
2. dp_altmode_work makes a call to tcpm_altmode_enter. The deadlock occurs
because tcpm_queue_vdm_unlock attempts to hold port->lock.

Before attempting to grab the lock, ensure that the port is in a state
vdm_run_state_machine can run in. Alt Mode unregistration will not occur
in these states.

2. tcpm_pd_event_handler() turns VBUS on before the port is in the default

3. The port resolves as a sink. In the SNK_DISCOVERY state,
tcpm_set_charge() cannot set vbus to charge.

Testing ohci functionality with qemu's pci-ohci emulation often results

The problem is caused by lost interrupts between the emulation and the

ASoC: meson: tdm fixes

Merge series from Jerome Brunet <[email protected]>:

This patchset fixes 2 problems on TDM which both find a solution
by properly implementing the .trigger() callback for the TDM backend.

ATM, enabling the TDM formatters is done by the .prepare() callback
because handling the formatter is slow due to necessary calls to CCF.

The first problem affects the TDMIN. Because .prepare() is called on DPCM
backend first, the formatter are started before the FIFOs and this may
cause a random channel shifts if the TDMIN use multiple lanes with more
than 2 slots per lanes. Using trigger() allows to set the FE/BE order,
solving the problem.

There has already been an attempt to fix this 3y ago [1] and reverted [2]
It triggered a 'sleep in irq' error on the period IRQ. The solution is
to just use the bottom half of threaded IRQ. This is patch #1. Patch #2
and #3 remain mostly the same as 3y ago.

For TDMOUT, the problem is on pause. ATM pause only stops the FIFO and
the TDMOUT just starves. When it does, it will actually repeat the last
sample continuously. Depending on the platform, if there is no high-pass
filter on the analog path, this may translate to a constant position of
the speaker membrane. There is no audible glitch but it may damage the
speaker coil.

Properly stopping the TDMOUT in pause solves the problem. There is
behaviour change associated with that fix. Clocks used to be continuous
on pause because of the problem above. They will now be gated on pause by
default, as they should. The last change introduce the proper support for
continuous clocks, if needed.

btrfs: set correct ram_bytes when splitting ordered extent

[BUG]
When running generic/287, the following file extent items can be
generated:

        item 16 key (258 EXTENT_DATA 2682880) itemoff 15305 itemsize 53
                generation 9 type 1 (regular)
                extent data disk byte 1378414592 nr 462848
                extent data offset 0 nr 462848 ram 2097152
                extent compression 0 (none)

Note that file extent item is not a compressed one, but its ram_bytes is
way larger than its disk_num_bytes.

According to btrfs on-disk scheme, ram_bytes should match disk_num_bytes
if it's not a compressed one.

[CAUSE]
Since commit b73a6fd1b1ef ("btrfs: split partial dio bios before
submit"), for partial dio writes, we would split the ordered extent.

However the function btrfs_split_ordered_extent() doesn't update the
ram_bytes even it has already shrunk the disk_num_bytes.

Originally the function btrfs_split_ordered_extent() is only introduced
for zoned devices in commit d22002fd37bd ("btrfs: zoned: split ordered
extent when bio is sent"), but later commit b73a6fd1b1ef ("btrfs: split
partial dio bios before submit") makes non-zoned btrfs affected.

Thankfully for un-compressed file extent, we do not really utilize the
ram_bytes member, thus it won't cause any real problem.

[FIX]
Also update btrfs_ordered_extent::ram_bytes inside
btrfs_split_ordered_extent().

x86/apic: Don't access the APIC when disabling x2APIC

With 'iommu=off' on the kernel command line and x2APIC enabled by the BIOS
the code which disables the x2APIC triggers an unchecked MSR access error:

  RDMSR from 0x802 at rIP: 0xffffffff94079992 (native_apic_msr_read+0x12/0x50)

This is happens because default_acpi_madt_oem_check() selects an x2APIC
driver before the x2APIC is disabled.

When the x2APIC is disabled because interrupt remapping cannot be enabled
due to 'iommu=off' on the command line, x2apic_disable() invokes
apic_set_fixmap() which in turn tries to read the APIC ID. This triggers
the MSR warning because x2APIC is disabled, but the APIC driver is still
x2APIC based.

Prevent that by adding an argument to apic_set_fixmap() which makes the
APIC ID read out conditional and set it to false from the x2APIC disable
path. That's correct as the APIC ID has already been read out during early
discovery.

x86/sev: Add callback to apply RMP table fixups for kexec

Handle cases where the RMP table placement in the BIOS is not 2M aligned
and the kexec-ed kernel could try to allocate from within that chunk
which then causes a fatal RMP fault.

The kexec failure is illustrated below:

  SEV-SNP: RMP table physical range [0x0000007ffe800000 - 0x000000807f0fffff]

aligned to 2MB and not reserved but it is usable as RAM.

Subsequently, kexec -s (KEXEC_FILE_LOAD syscall) loads it's purgatory
code and boot_param, command line and other setup data into this RAM

softirq: Fix suspicious RCU usage in __do_softirq()

Currently, the condition "__this_cpu_read(ksoftirqd) == current" is used to
invoke rcu_softirq_qs() in ksoftirqd tasks context for non-RT kernels.

This works correctly as long as the context is actually task context but
this condition is wrong when:

     - the current task is ksoftirqd
     - the task is interrupted in a RCU read side critical section
     - __do_softirq() is invoked on return from interrupt

Syzkaller triggered the following scenario:

  -> finish_task_switch()
    -> put_task_struct_rcu_user()
      -> call_rcu(&task->rcu, delayed_put_task_struct)
        -> __kasan_record_aux_stack()
          -> pfn_valid()
            -> rcu_read_lock_sched()
              <interrupt>
                __irq_exit_rcu()
                -> __do_softirq)()
                   -> if (!IS_ENABLED(CONFIG_PREEMPT_RT) &&
                     __this_cpu_read(ksoftirqd) == current)
                     -> rcu_softirq_qs()
                       -> RCU_LOCKDEP_WARN(lock_is_held(&rcu_sched_lock_map))

The rcu quiescent state is reported in the rcu-read critical section, so
the lockdep warning is triggered.

Fix this by splitting out the inner working of __do_softirq() into a helper
function which takes an argument to distinguish between ksoftirqd task
context and interrupted context and invoke it from the relevant call sites
with the proper context information and use that for the conditional
invocation of rcu_softirq_qs().

ALSA: emu10k1: use mutex for E-MU FPGA access locking

The FPGA access through the GPIO port does not interfere with other
sound processor register access, so there is no need to subject it to
emu_lock. And after moving all FPGA access out of the interrupt handler,
it does not need to be IRQ-safe, either.

What's more, attaching the dock causes a firmware upload, which takes
several seconds. We really don't want to disable IRQs for this long, and
even less also have someone else spin with IRQs disabled waiting for us.

Therefore, use a mutex for FPGA access locking.

This makes the code somewhat more noisy, as we need to wrap bigger
sections into the mutex, as it needs to enclose the spinlocks.

The latter has the "side effect" of fixing dock FPGA programming in a
corner case: a really badly timed mixer access right between entering
FPGA programming mode and uploading the netlist would mess up the
protocol.

ALSA: emu10k1: move the whole GPIO event handling to the workqueue

move the event dispatching there as well, rather than doing it already
in the interrupt handler callback.

This change has a rather profound "side effect" on the reliability of
the FPGA programming: once we enter programming mode, we must not issue
any snd_emu1010_fpga_{read,write}() calls until we're done, as these
would badly mess up the programming protocol. But exactly that would
happen when trying to program the dock, as that triggers GPIO interrupts
as a side effect. This is mitigated by deferring the actual interrupt
handling, as workqueue items are not re-entrant.

To avoid scheduling the dispatcher on non-events, we now explicitly
ignore GPIO IRQs triggered by "uninteresting" pins, which happens a lot

sched/isolation: Fix boot crash when maxcpus < first housekeeping CPU

housekeeping_setup() checks cpumask_intersects(present, online) to ensure
that the kernel will have at least one housekeeping CPU after smp_init(),
but this doesn't work if the maxcpus= kernel parameter limits the number of
processors available after bootup.

For example, a kernel with "maxcpus=2 nohz_full=0-2" parameters crashes at
boot time on a virtual machine with 4 CPUs.

Change housekeeping_setup() to use cpumask_first_and() and check that the
returned CPU number is valid and less than setup_max_cpus.

Another corner case is "nohz_full=0" on a machine with a single CPU or with
the maxcpus=1 kernel argument. In this case non_housekeeping_mask is empty
and tick_nohz_full_setup() makes no sense. And indeed, the kernel hits the
WARN_ON(tick_nohz_full_running) in tick_sched_do_timer().

And how should the kernel interpret the "nohz_full=" parameter? It should
be silently ignored, but currently cpulist_parse() happily returns the
empty cpumask and this leads to the same problem.

Change housekeeping_setup() to check cpumask_empty(non_housekeeping_mask)
and do nothing in this case.

housekeeping CPU up.

Change housekeeping_any_cpu() to check the result of cpumask_any_and() and

   - The Qualcomm MSI support that was improved for 6.9 ended up being
     wrong on some chips and now gets fixed.

   - The i.MX8MP camera interface broke due to a typo and gets updated
     again.

  The main driver fix is also for Qualcomm platforms, rewriting an
  interface in the QSEECOM firmware support that could lead to crashing
  the kernel from a trusted application.
