5e931c88b6 drm/edid: Avoid multiple log lines for HFVSDB parsing
Replace multiple log lines with a single log line at the end of
parsing HF-VSDB. Also use drm_dbg_kms instead of DRM_DBG_KMS, and
add log for DSC1.2 support.

v2: Fixed the formatting issues in the logging (Jani).

a07e6f56b3 drm/edid: Refactor HFVSDB parsing for DSC1.2
DSC capabilities are given in bytes 11-13 of VSDB (i.e. bytes 8-10 of
SCDS). Since minimum length of Data block is 7, all bytes greater than 7
must be read only after checking the length of the data block.

This patch adds check for data block length before reading relavant DSC
bytes.

18feaf6d07 drm/edid: Fix minimum bpc supported with DSC1.2 for HDMI sink
HF-VSDB/SCDB has bits to advertise support for 16, 12 and 10 bpc.
If none of the bits are set, the minimum bpc supported with DSC is 8.

This patch corrects the min bpc supported to be 8, instead of 0.

bd04b9192e ceph: fail the open_by_handle_at() if the dentry is being unlinked
When unlinking a file the kclient will send a unlink request to MDS
by holding the dentry reference, and then the MDS will return 2 replies,
which are unsafe reply and a deferred safe reply.

After the unsafe reply received the kernel will return and succeed
the unlink request to user space apps.

Only when the safe reply received the dentry's reference will be
released. Or the dentry will only be unhashed from dcache. But when
the open_by_handle_at() begins to open the unlinked files it will
succeed.

The inode->i_count couldn't be used to check whether the inode is
opened or not.

7c3ea9870e ceph: no need to wait for transition RDCACHE|RD -> RD
For write when trying to get the Fwb caps we need to keep waiting
on transition from WRBUFFER|WR -> WR to avoid a new WR sync write
from going before a prior buffered writeback happens.

While for read there is no need to wait on transition from
RDCACHE|RD -> RD, and we can just exclude the revoking caps and
force to sync read.

42172b551c drm/i915: Document and future-proof preemption control policy
Intel hardware allows some preemption settings to be controlled either
by the kernel-mode driver exclusively, or placed under control of the
user-mode drivers; on Linux we always select the userspace control
option.  The various registers involved in this are not documented very
clearly; let's add some clarifying comments to help explain how this all
works and provide some history on why our Linux drivers take the
approach they do (which I believe differs from the path taken by certain
other operating systems' drivers).

While we're at it, let's also remove the graphics version 12 upper bound
on this programming.  As described, we don't have any plans to move away
from UMD control of preemption settings on future platforms, and there's
currently no reason to believe that the hardware will fundamentally
change how these registers and settings work after version 12.

728c2edfcf xen-pcifront: Handle missed Connected state
An HVM guest with linux stubdomain and 2 PCI devices failed to start as
libxl timed out waiting for the PCI devices to be added.  It happens
intermittently but with some regularity.  libxl wrote the two xenstore
entries for the devices, but then timed out waiting for backend state 4
(Connected) - the state stayed at 7 (Reconfiguring).  (PCI passthrough
to an HVM with stubdomain is PV passthrough to the stubdomain and then
HVM passthrough with the QEMU inside the stubdomain.)

The stubdomain kernel never printed "pcifront pci-0: Installing PCI
frontend", so it seems to have missed state 4 which would have
called pcifront_try_connect() -> pcifront_connect_and_init_dma()

Have pcifront_detach_devices() special-case state Initialised and call
pcifront_connect_and_init_dma().  Don't use pcifront_try_connect()
because that sets the xenbus state which may throw off the backend.
After connecting, skip the remainder of detach_devices since none have
been initialized yet.  When the backend switches to Reconfigured,
pcifront_attach_devices() will pick them up again.

415fed694f ACPI: APEI: do not add task_work to kernel thread to avoid memory leak
If an error is detected as a result of user-space process accessing a
corrupt memory location, the CPU may take an abort. Then the platform
firmware reports kernel via NMI like notifications, e.g. NOTIFY_SEA,
NOTIFY_SOFTWARE_DELEGATED, etc.

For NMI like notifications, commit 7f17b4a121 ("ACPI: APEI: Kick the
memory_failure() queue for synchronous errors") keep track of whether
memory_failure() work was queued, and make task_work pending to flush out
the queue so that the work is processed before return to user-space.

The code use init_mm to check whether the error occurs in user space:

    if (current->mm != &init_mm)

The condition is always true, becase _nobody_ ever has "init_mm" as a real
VM any more.

In addition to abort, errors can also be signaled as asynchronous
exceptions, such as interrupt and SError. In such case, the interrupted
current process could be any kind of thread. When a kernel thread is
interrupted, the work ghes_kick_task_work deferred to task_work will never
be processed because entry_handler returns to call ret_to_kernel() instead
of ret_to_user(). Consequently, the estatus_node alloced from
ghes_estatus_pool in ghes_in_nmi_queue_one_entry() will not be freed.
After around 200 allocations in our platform, the ghes_estatus_pool will
run of memory and ghes_in_nmi_queue_one_entry() returns ENOMEM. As a
result, the event failed to be processed.

    sdei: event 805 on CPU 113 failed with error: -2

Finally, a lot of unhandled events may cause platform firmware to exceed
some threshold and reboot.

The condition should generally just do

    if (current->mm)

as described in active_mm.rst documentation.

Then if an asynchronous error is detected when a kernel thread is running,
(e.g. when detected by a background scrubber), do not add task_work to it
as the original patch intends to do.

Using S5 for reboot is default behavior under Windows: "A full shutdown

a6c05e1223 ACPI: PM: Take wake IRQ into consideration when entering suspend-to-idle
This change adds support for ACPI devices that use ExclusiveAndWake or
SharedAndWake in their _CRS GpioInt definition (instead of using _PRW),
and also provide power resources. Previously the ACPI subsystem had no
idea if the device had a wake capable interrupt armed. This resulted
in the ACPI device PM system placing the device into D3Cold, and thus
cutting power to the device. With this change we will now query the
_S0W method to figure out the appropriate wake capable D-state.

b38f2d5d96 i2c: acpi: Use ACPI wake capability bit to set wake_irq
Device tree already has a mechanism to pass the wake_irq. It does this
by looking for the wakeup-source property and setting the
I2C_CLIENT_WAKE flag. This CL adds the ACPI equivalent. It uses the
ACPI interrupt wake flag to determine if the interrupt can be used to
wake the system. Previously the i2c drivers had to make assumptions and
blindly enable the wake IRQ. This can cause spurious wake events. e.g.,
If there is a device with an Active Low interrupt and the device gets
powered off while suspending, the interrupt line will go low since it's
no longer powered and wakes the system. For this reason we should
respect the board designers wishes and honor the wake bit defined on the
interrupt.
