Report event FAN_DIR_MODIFY with name in a variable length record similar
to how fid's are reported. With name info reporting implemented, setting
FAN_DIR_MODIFY in mark mask is now allowed.
When events are reported with name, the reported fid identifies the
directory and the name follows the fid. The info record type for this
event info is FAN_EVENT_INFO_TYPE_DFID_NAME.
For now, all reported events have at most one info record which is
either FAN_EVENT_INFO_TYPE_FID or FAN_EVENT_INFO_TYPE_DFID_NAME (for
FAN_DIR_MODIFY). Later on, events "on child" will report both records.
There are several ways that an application can use this information:
1. When watching a single directory, the name is always relative to
the watched directory, so application need to fstatat(2) the name
relative to the watched directory.
2. When watching a set of directories, the application could keep a map
of dirfd for all watched directories and hash the map by fid obtained
with name_to_handle_at(2). When getting a name event, the fid in the
event info could be used to lookup the base dirfd in the map and then
call fstatat(2) with that dirfd.
3. When watching a filesystem (FAN_MARK_FILESYSTEM) or a large set of
directories, the application could use open_by_handle_at(2) with the fid
in event info to obtain dirfd for the directory where event happened and
call fstatat(2) with this dirfd.
The last option scales better for a large number of watched directories.
The first two options may be available in the future also for non
privileged fanotify watchers, because open_by_handle_at(2) requires
the CAP_DAC_READ_SEARCH capability.

For FAN_DIR_MODIFY event, allocate a variable size event struct to store
the dir entry name along side the directory file handle.
At this point, name info reporting is not yet implemented, so trying to
set FAN_DIR_MODIFY in mark mask will return -EINVAL.

Recent series of patches targeting broadwell boards, while enabling
SOF, changed behavior for non-SOF solutions. In essence replacing
platform 'dummy' with actual 'platform' causes redundant stream
initialization to occur during audio start. hw_params for haswell-pcm
destroys initial stream right after its creation - only to recreate it
again from proceed from there.
While harmless so far, this flow isn't right and should be corrected.
The actual need for dummy components for SSP0 link is questionable but
that issue is subject for another series.

Commit '16f17eda8b ("drm/amd/display: Send vblank and user
events at vsartup for DCN")' introduces a new way of pageflip
completion handling for DCN, and some trouble.
The current implementation introduces a race condition, which
can cause pageflip completion events to be sent out one vblank
too early, thereby confusing userspace and causing flicker:
prepare_flip_isr():
1. Pageflip programming takes the ddev->event_lock.
2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED
3. Releases ddev->event_lock.
--> Deadline for surface address regs double-buffering passes on
target pipe.
4. dc_commit_updates_for_stream() MMIO programs the new pageflip
into hw, but too late for current vblank.
=> pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete
in current vblank due to missing the double-buffering deadline
by a tiny bit.
5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires,
dm_dcn_crtc_high_irq() gets called.
6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the
pageflip has been completed/will complete in this vblank and
sends out pageflip completion event to userspace and resets
pflip_status = AMDGPU_FLIP_NONE.
=> Flip completion event sent out one vblank too early.
This behaviour has been observed during my testing with measurement
hardware a couple of time.
The commit message says that the extra flip event code was added to
dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events
in case the pflip irq doesn't fire, because the "DCH HUBP" component
is clock gated and doesn't fire pflip irqs in that state. Also that
this clock gating may happen if no planes are active. This suggests
that the problem addressed by that commit can't happen if planes
are active.
The proposed solution is therefore to only execute the extra pflip
completion code iff the count of active planes is zero and otherwise
leave pflip completion handling to the pflip irq handler, for a
more race-free experience.
Note that i don't know if this fixes the problem the original commit
tried to address, as i don't know what the test scenario was. It
does fix the observed too early pageflip events though and points
out the problem introduced.

These changes add support for the XUSB pad controller, as well as the
XUSB controller on Tegra194. Furthermore, USB device mode is supported
across Tegra210 and Tegra186 boards. PCIe endpoint mode support is added
for the Jetson AGX Xavier platform.
Various minor fixes eliminate warnings on boot related to missing power
supplies for some devices.
