Mukesh Ojha c35dd83866 KVM: arm64: Guard PMSCR_EL1 initialization with SPE presence check
Commit efad60e460 ("KVM: arm64: Initialize PMSCR_EL1 when in VHE")
does not perform sufficient check before initializing PMSCR_EL1 to 0
when running in VHE mode. On some platforms, this causes the system to
hang during boot, as EL3 has not delegated access to the Profiling
Buffer to the Non-secure world, nor does it reinject an UNDEF on sysreg
trap.

To avoid this issue, restrict the PMSCR_EL1 initialization to CPUs that
support Statistical Profiling Extension (FEAT_SPE) and have the
Profiling Buffer accessible in Non-secure EL1. This is determined via a
new helper `cpu_has_spe()` which checks both PMSVer and PMBIDR_EL1.P.

This ensures the initialization only affects CPUs where SPE is
implemented and usable, preventing boot failures on platforms where SPE
is not properly configured.

Stefan Metzmacher 1ef0e16c3d smb: client: let destroy_mr_list() call ib_dereg_mr() before ib_dma_unmap_sg()
This is more consistent as we call ib_dma_unmap_sg() only
when the memory is no longer registered.

This is the same pattern as calling ib_dma_unmap_sg() after
IB_WR_LOCAL_INV.

Oliver Upton a133052666 KVM: selftests: Fix irqfd_test for non-x86 architectures
The KVM_IRQFD ioctl fails if no irqchip is present in-kernel, which
isn't too surprising as there's not much KVM can do for an IRQ if it
cannot resolve a destination.

As written the irqfd_test assumes that a 'default' VM created in
selftests has an in-kernel irqchip created implicitly. That may be the
case on x86 but it isn't necessarily true on other architectures.

Add an arch predicate indicating if 'default' VMs get an irqchip and
make the irqfd_test depend on it. Work around arm64 VGIC initialization
requirements by using vm_create_with_one_vcpu(), ignoring the created
vCPU as it isn't used for the test.

Oliver Upton 0aa1b76fe1 KVM: arm64: Prevent access to vCPU events before init
Another day, another syzkaller bug. KVM erroneously allows userspace to
pend vCPU events for a vCPU that hasn't been initialized yet, leading to
KVM interpreting a bunch of uninitialized garbage for routing /
injecting the exception.

In one case the injection code and the hyp disagree on whether the vCPU
has a 32bit EL1 and put the vCPU into an illegal mode for AArch64,
tripping the BUG() in exception_target_el() during the next injection:

Cristian Ciocaltea ee70bacef1 ASoC: nau8821: Avoid unnecessary blocking in IRQ handler
The interrupt handler offloads the microphone detection logic to
nau8821_jdet_work(), which implies a sleep operation.  However, before
being able to process any subsequent hotplug event, the interrupt
handler needs to wait for any prior scheduled work to complete.

Move the sleep out of jdet_work by converting it to a delayed work.
This eliminates the undesired blocking in the interrupt handler when
attempting to cancel a recently scheduled work item and should help
reducing transient input reports that might confuse user-space.

Cristian Ciocaltea 2b4eda7bf7 ASoC: nau8821: Add DMI quirk to bypass jack debounce circuit
Stress testing the audio jack hotplug handling on a few Steam Deck units
revealed that the debounce circuit is responsible for having a negative
impact on the detection reliability, e.g. in some cases the ejection
interrupt is not fired, while in other instances it goes into a kind of
invalid state and generates a flood of misleading interrupts.

Add new entries to the DMI table introduced via commit 1bc40efdaf
("ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect")
and extend the quirk logic to allow bypassing the debounce circuit used
for jack detection on Valve Steam Deck LCD and OLED models.

While at it, rename existing NAU8821_JD_ACTIVE_HIGH quirk bitfield to
NAU8821_QUIRK_JD_ACTIVE_HIGH.  This should help improve code readability
by differentiating from similarly named register bits.

Cristian Ciocaltea a698679fe8 ASoC: nau8821: Consistently clear interrupts before unmasking
The interrupt handler attempts to perform some IRQ status clear
operations *after* rather than *before* unmasking and enabling
interrupts.  This is a rather fragile approach since it may generally
lead to missing IRQ requests or causing spurious interrupts.

Make use of the nau8821_irq_status_clear() helper instead of
manipulating the related register directly and ensure any interrupt
clearing is performed *after* the target interrupts are disabled/masked
and *before* proceeding with additional interrupt unmasking/enablement
operations.

This also implicitly drops the redundant clear operation of the ejection
IRQ in the interrupt handler, since nau8821_eject_jack() has been
already responsible for clearing all active interrupts.

Cristian Ciocaltea 6e54919cb5 ASoC: nau8821: Cancel jdet_work before handling jack ejection
The microphone detection work scheduled by a prior jack insertion
interrupt may still be in a pending state or under execution when a jack
ejection interrupt has been fired.

This might lead to a racing condition or nau8821_jdet_work() completing
after nau8821_eject_jack(), which will override the currently
disconnected state of the jack and incorrectly report the headphone or
the headset as being connected.

Cancel any pending jdet_work or wait for its execution to finish before
attempting to handle the ejection interrupt.

Proceed similarly before launching the eject handler as a consequence of
detecting an invalid insert interrupt.

Sudeep Holla 11fb1a82ae firmware: arm_ffa: Add support for IMPDEF value in the memory access descriptor
FF-A v1.2 introduced 16 byte IMPLEMENTATION DEFINED value in the endpoint
memory access descriptor to allow any sender could to specify an its any
custom value for each receiver. Also this value must be specified by the
receiver when retrieving the memory region. The sender must ensure it
informs the receiver of this value via an IMPLEMENTATION DEFINED mechanism
such as a partition message.

So the FF-A driver can use the message interfaces to communicate the value
and set the same in the ffa_mem_region_attributes structures when using
the memory interfaces.

The driver ensure that the size of the endpoint memory access descriptors
is set correctly based on the FF-A version.

Alice Ryhl b5ce7a5cc5 rust_binder: report freeze notification only when fully frozen
Binder only sends out freeze notifications when ioctl_freeze() completes
and the process has become fully frozen. However, if a freeze
notification is registered during the freeze operation, then it
registers an initial state of 'frozen'. This is a problem because if
the freeze operation fails, then the listener is not told about that
state change, leading to lost updates.

Alice Ryhl 99559e5bb4 rust_binder: don't delete FreezeListener if there are pending duplicates
When userspace issues commands to a freeze listener, it identifies it
using a cookie. Normally this cookie uniquely identifies a freeze
listener, but when userspace clears a listener with the intent of
deleting it, it's allowed to "regret" clearing it and create a new
freeze listener for the same node using the same cookie. (IMO this was
an API mistake, but userspace relies on it.)

Currently if the active freeze listener gets fully deleted while there
are still pending duplicates, then the code incorrectly deletes the
pending duplicates too. To fix this, do not delete the entry if there
are still pending duplicates.

Since the current data structure requires a main freeze listener, we
convert one pending duplicate into the primary listener in this
scenario.

3. The message for step 2 is delivered to thread 2 and ignored because

4. Thread 1 acknowledges the notification from step 1.

Dave Penkler 92a2b74a6b staging: gpib: Fix sending clear and trigger events
This driver was not sending device clear or trigger events when the
board entered the DCAS or DTAS state respectively in device mode.

DCAS is the Device Clear Active State which is entered on receiving a
selective device clear message (SDC) or universal device clear message
(DCL) from the controller in charge.

DTAS is the Device Trigger Active State which is entered on receiving
a group execute trigger (GET) message from the controller.

In order for an application, implementing a particular device, to
detect when one of these states is entered the driver needs to send
the appropriate event.

Send the appropriate gpib_event when DCAS or DTAS is set in the
reported status word. This sets the DCAS or DTAS bits in the board's
status word which can be monitored by the application.

Dave Penkler d3c4c1f29a staging: gpib: Fix no EOI on 1 and 2 byte writes
EOI (End Or Identify) is a hardware line on the GPIB bus that can be
asserted with the last byte of a message to indicate the end of the
transfer to the receiving device.

In this driver, a write with send_eoi true is done in 3 parts:
  Send first byte directly
  Send remaining but 1 bytes using the fifo
  Send the last byte directly with EOI asserted

The first byte in a write is always sent by writing to the tms9914
chip directly to setup for the subsequent fifo transfer.  We were not
checking for a 1 byte write with send_eoi true resulting in EOI not
being asserted. Since the fifo transfer was not executed
(fifotransfersize == 0) the retval in the test after the fifo transfer
code was still 1 from the preceding direct write. This caused it to
return without executing the final direct write which would have sent
an unsollicited extra byte.

For a 2 byte message the first byte was sent directly. But since the
fifo transfer was not executed (fifotransfersize == 1) and the retval
in the test after the fifo transfer code was still 1 from the
preceding first byte write it returned before the final direct byte
write with send_eoi true. The second byte was then sent as a separate
1 byte write to complete the 2 byte write count again without EOI
being asserted as above.

Only send the first byte directly if more than 1 byte is to be
transferred with send_eoi true.

Also check for retval < 0 for the error return in case the fifo code
is not used (1 or 2 byte message with send_eoi true).
