engine->stats is a union of execlist and guc stat objects. When execlist
specific fields are initialized, the initial state of guc stats is
affected. This results in bad busyness values when using GuC mode. Move
the execlist initialization from common code to execlist specific code.

Invalidate instruction and State cache bit using INDIRECT_CTX on
every gpu context switch for gen12.
The goal of this workaround is to actually perform an explicit
invalidation of that cache (by re-writing the register) during every GPU
context switch, which is accomplished via a "workaround batchbuffer"
that's attached to the context via INDIRECT_CTX. (Matt Roper)

Remove the i915 specific i2c-N symlink from HDMI connectors.
This was added to sort of mirror the DP connectors that alreayd
had their aux ch based i2c adapter sitting beneath them in the
sysfs hierarchy. But now that we have the standard "ddc" symlink
approach provided by the core let's switch to that fully.

Populate connector->ddc, and thus create the "ddc" symlink

As a bonus we can replace a bunch of intel_gmbus_get_adapter()
lookups with just the connector->ddc pointer. Sadly one extra
lookup still remains due to the g4x DVI-I shenanigans. We could
perhaps consider borrowing the ddc proxy idea from SDVO to deal
with that in a perhaps nicer way, but can't really be bothered
right now at least. Also not sure exposing such a dual ddc bus

Currently drm_sysfs_connector_add() attempts to register
the "ddc" symlink (based one connector->ddc) before the
driver's .early_register() hook has been called. That is
too early for i915 which only fully registers the aux ch
and associated i2c bus from said hook (to prevent half
initialized stuff getting exposed to userspace). This
causes my attempt at using drm_connector_init_with_ddc()
to fail, and the entire connector disappears from sysfs
on account of sysfs_create_link() failing.
To fix that split the sysfs symlink stuff into separate
functions (drm_sysfs_connector_add_late() and
drm_sysfs_connector_remove_early()) which are called
on the opposite side of the .later_register() and
.early_unregister() hooks.

Commit:
5a5d7e9bad ("cpuidle: lib/bug: Disable rcu_is_watching() during WARN/BUG")
amended warn_slowpath_fmt() to disable preemption until the WARN splat
has been emitted.
However the commit neglected to reenable preemption in the !fmt codepath,
i.e. when a WARN splat is emitted without additional format string.
One consequence is that users may see more splats than intended. E.g. a
WARN splat emitted in a work item results in at least two extra splats:
BUG: workqueue leaked lock or atomic
(emitted by process_one_work())
BUG: scheduling while atomic
(emitted by worker_thread() -> schedule())
Ironically the point of the commit was to *avoid* extra splats. ;)
Fix it.

Signed-off-by: Steve French <stfrench@microsoft.com>
When a CRC error occurs, the HBA asserts an interrupt to indicate an
interface fatal error (PxIS.IFS). The ISR clears PxIE and PxIS, then
does error recovery. If the adapter receives another SDB FIS
with an error (PxIS.TFES) from the device before the start of the EH
recovery process, the interrupt signaling the new SDB cannot be
serviced as PxIE was cleared already. This in turn results in the HBA
inability to issue any command during the error recovery process after
setting PxCMD.ST to 1 because PxIS.TFES is still set.
According to AHCI 1.3.1 specifications section 6.2.2, fatal errors
notified by setting PxIS.HBFS, PxIS.HBDS, PxIS.IFS or PxIS.TFES will
cause the HBA to enter the ERR:Fatal state. In this state, the HBA
shall not issue any new commands.
To avoid this situation, introduce the function
ahci_port_clear_pending_irq() to clear pending interrupts before
executing a COMRESET. This follows the AHCI 1.3.1 - section 6.2.2.2
specification.

Some devices are reporting controller ready mode support, but return 0
for CRTO. These devices require a much higher time to ready than that,
so they are failing to initialize after the driver starter preferring
that value over CAP.TO.
The spec requires that CAP.TO match the appropritate CRTO value, or be
set to 0xff if CRTO is larger than that. This means that CAP.TO can be
used to validate if CRTO is reliable, and provides an appropriate
fallback for setting the timeout value if not. Use whichever is larger.

The commit 45b58669e5 ("drm/ssd130x: Allocate buffer in the plane's
.atomic_check() callback") moved the allocation of the intermediate and
HW buffers from the encoder's .atomic_enable callback, to the plane's
.atomic_check callback.
This was suggested by Maxime Ripard, because drivers aren't allowed to
fail after the drm_atomic_helper_swap_state() function has been called.
And the encoder's .atomic_enable happens after the new atomic state has
been swapped, so allocations (that can fail) shouldn't be done there.
But the HW buffer isn't really tied to the plane's state. It has a fixed
size that only depends on the (also fixed) display resolution defined in
the Device Tree Blob.
That buffer can be considered part of the CRTC state, and for this reason
makes more sense to do its allocation in the CRTC .atomic_check callback.
The other allocated buffer (used to store a conversion from the emulated
XR24 format to the native R1 format) is part of the plane's state, since
it will be optional once the driver supports R1 and allows user-space to
set that pixel format.
So let's keep the allocation for it in the plane's .atomic_check callback,
this can't be moved to the CRTC's .atomic_check because changing a format
does not trigger a CRTC mode set.

With the configuration PAGE_SIZE 64k and filesystem blocksize 64k,
a problem occurred when more than 13 million files were directly created
under a directory:
EXT4-fs error (device xx): ext4_dx_csum_set:492: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D.
EXT4-fs error (device xx): ext4_dx_csum_verify:463: inode #xxxx: comm xxxxx: dir seems corrupt? Run e2fsck -D.
EXT4-fs error (device xx): dx_probe:856: inode #xxxx: block 8188: comm xxxxx: Directory index failed checksum
When enough files are created, the fake_dirent->reclen will be 0xffff.
it doesn't equal to the blocksize 65536, i.e. 0x10000.
But it is not the same condition when blocksize equals to 4k.
when enough files are created, the fake_dirent->reclen will be 0x1000.
it equals to the blocksize 4k, i.e. 0x1000.
The problem seems to be related to the limitation of the 16-bit field
when the blocksize is set to 64k.
To address this, helpers like ext4_rec_len_{from,to}_disk has already
been introduced to complete the conversion between the encoded and the
plain form of rec_len.
So fix this one by using the helper, and all the other in this file too.

Len Brown has reported that system suspend sometimes fail due to
inability to freeze a task working in ext4_trim_fs() for one minute.
Trimming a large filesystem on a disk that slowly processes discard
requests can indeed take a long time. Since discard is just an advisory
call, it is perfectly fine to interrupt it at any time and the return
number of discarded blocks until that moment. Do that when we detect the
task is being frozen.

Currently we set the group's trimmed bit in ext4_trim_all_free() based
on return value of ext4_try_to_trim_range(). However when we will want
to abort trimming because of suspend attempt, we want to return success
from ext4_try_to_trim_range() but not set the trimmed bit. Instead
implementing awkward propagation of this information, just move setting
of trimmed bit into ext4_try_to_trim_range() when the whole group is
trimmed.
