In the current vendor hook, if next_uptodate_folio returns NULL, the
first_pgoff is set to zero, and the last_pgoff is set to start_pgoff.
Therefore, the collection range is from 0 to the start_pgoff.
|-----------|------------|-------------|------------------|
0 start_pgoff first_pgoff last_pgoff end_pgoff
We want to collect the first_pgoff to last_pgoff, so we have to add a
new vendor hook.

Allow the memfd-ashmem-shim ioctl handler to run for any shmem file,
so that memfds can handle ashmem ioctl commands.
While this allows ashmem ioctl commands to be invoked on more than just
memfds, this should be fine, since the ioctl commands don't expose any
additional functionality than what is already achievable via other
system calls.

Certain applications treat any shared memory buffer that they obtain
as an ashmem buffer, meaning that they will attempt to invoke ashmem
ioctl commands on that buffer.
Android is transitioning to replacing ashmem with memfd, and memfd
currently does not support ashmem ioctl commands. So, when an
application attempts to invoke an ashmem ioctl command on a memfd,
the invocation will fail and report an error back to the app.
In order to preserve compatibility between these apps and memfds,
add a shim layer which will handle ashmem ioctl commands for memfds.

Memfd does not support preventing a file from being mapped with PROT_EXEC,
as ashmem does. It would be useful to expose a knob to userspace to
change ashmem's behavior to match memfd to see if any issues arise
during tests.
Therefore, expose a tunable that userspace can use to cause ashmem to
ignore requests to deny PROT_EXEC mappings.

The final version of ashmem will not support unpinning buffers.
Therefore, to be able to have the ashmem driver behave as close as
possible to its final configuration for testing, add a device node
that can be used to disable unpinning.
This node will make it so that the ashmem shrinker stops running,
and that all unpinning requests are ignored.

The Source can drop its output voltage to the minimum of the requested
PPS APDO voltage range when it is in Current Limit Mode. If this voltage
falls within the range of vPpsShutdown, the Source initiates a Hard
Reset and discharges Vbus. However, currently the Sink may disconnect
before the voltage reaches vPpsShutdown, leading to unexpected behavior.
Prevent premature disconnection by setting the Sink's disconnect
threshold to the minimum vPpsShutdown value. Additionally, consider the
voltage drop due to IR drop when calculating the appropriate threshold.
This ensures a robust and reliable interaction between the Source and
Sink during SPR PPS Current Limit Mode operation.

Below race case can cause data corruption:
Thread A GC thread

- ra_data_block
- locked meta_inode page
- f2fs_inplace_write_data
- invalidate_mapping_pages
: fail to invalidate meta_inode page
due to lock failure or dirty|writeback

- f2fs_submit_page_bio
: write last dirty data to old blkaddr
- move_data_block
- load old data from meta_inode page
- f2fs_submit_page_write
: write old data to new blkaddr
Because invalidate_mapping_pages() will skip invalidating page which
has unclear status including locked, dirty, writeback and so on, so
we need to use truncate_inode_pages_range() instead of
invalidate_mapping_pages() to make sure meta_inode page will be dropped.

Commit "mm,page_alloc,cma: conditionally prefer cma pageblocks for
movable allocations" (1686766493) introduced balancing of movable
allocations between CMA and normal areas.
Commit "ANDROID: cma: redirect page allocation to CMA" (f60c5572d2)
removes it, making allocations go in CMA area first.
1. Reintroduce the condition, so that CMA and normal area are used
in a balanced way(as it used to be), so it prevents depleting of CMA
region;
2. Back-port a command line option(from 6.6), "restrict_cma_redirect",
that can be used if only MOVABLE allocations marked as __GFP_CMA are
eligible to be redirected to CMA region. By default it is true.
The purpose of this change is to keep using CMA for movable allocations,
but at the same time, to have enough free CMA pages for critical system
areas such as modem initialization, GPU initialization and so on.

When allocating guest stage-2 page-table pages at EL2, pKVM can consume
pages from the host-provided kvm_hyp_memcache. As pgtable.c expects
zeroed pages, guest_s2_zalloc_page() actively implements this zeroing
with a PAGE_SIZE memset. Unfortunately, we don't check the page
alignment of the host-provided address before doing so, which could
lead to the memset overrunning the page if the host was malicious.
Fix this by simply force-aligning all kvm_hyp_memcache allocations to
page boundaries.

This change adds an android_trigger_vendor_lmk_kill() trace event
which can be used by vendor modules to send LMKD kill requests.
LMKD attaches a BPF program to this trace event if it exists and
expects it to be in a particular format. To provide a standardized
definition for this event, we define and export it inside the GKI
even though there are no users. Android vendors can use this event
to emit this trace event inside their modules and experiment with
different kill strategies before upstreaming them into LMKD.

If a command is queued to the final usable TRB of a ring segment, the
enqueue pointer is advanced to the subsequent link TRB and no further.
If the command is later aborted, when the abort completion is handled
the dequeue pointer is advanced to the first TRB of the next segment.
If no further commands are queued, xhci_handle_stopped_cmd_ring() sees
the ring pointers unequal and assumes that there is a pending command,
so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL.
Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell
ring likely is unnecessary too, but it's harmless. Leave it alone.
This is probably Bug 219532, but no confirmation has been received.
The issue has been independently reproduced and confirmed fixed using
a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever.
Everything continued working normally after several prevented crashes.

Commit b50a013d33 ("BACKPORT: OPP: Extend support for the opp-level
beyond required-opps") used dev_pm_genpd_set_performance_state()
as a substitute for dev_pm_domain_set_performance_state(), since
introducing dev_pm_domain_set_performance_state() required breaking the
ABI on this branch.
However, directly invoking dev_pm_genpd_set_performance_state() is not
equivalent to dev_pm_domain_set_performance_state(), as the latter
only invokes a PM domain's set_performance_state callback if the device
it is invoked on uses a PM domain, and if that PM domain supports that
callback. If that check fails, then the invocation is simply a nop, and
no error code is returned.
In contrast, dev_pm_genpd_set_performance_state() checks to ensure that the
device uses a PM domain, and that the PM domain is a generic PM domain.
If that is not the case, then the invocation returns an error which is
then propagated up the call chain.
Therefore, fix _set_opp_level() to function as a nop for devices without
PM domains to align it to its original intent.

commit 48c6253fef upstream.
'Headphone Switch' control is already registered from
sound/soc/codecs/wm_hubs.c:479, so duplicating it in midas_wm1811
causes following probe failure:
midas-audio sound: control 2:0:0:Headphone Switch:0 is already present
midas-audio sound: ASoC: Failed to add Headphone Switch: -16
midas-audio sound: Failed to register card: -16
midas-audio: probe of sound failed with error -16
Fix this by dropping duplicated control.
