commit 0b207d02bd9ab8dcc31b262ca9f60dbc1822500d upstream.

rbd_dev_refresh() has been holding header_rwsem across header and
parent info read-in unnecessarily for ages.  With commit 870611e4877e
("rbd: get snapshot context after exclusive lock is ensured to be
held"), the potential for deadlocks became much more real owning to
a) header_rwsem now nesting inside lock_rwsem and b) rw_semaphores
not allowing new readers after a writer is registered.

For example, assuming that I/O request 1, I/O request 2 and header
read-in request all target the same OSD:

1. I/O request 1 comes in and gets submitted
2. watch error occurs
3. rbd_watch_errcb() takes lock_rwsem for write, clears owner_cid and
   releases lock_rwsem
4. after reestablishing the watch, rbd_reregister_watch() calls
   rbd_dev_refresh() which takes header_rwsem for write and submits
   a header read-in request
5. I/O request 2 comes in: after taking lock_rwsem for read in
   __rbd_img_handle_request(), it blocks trying to take header_rwsem
   for read in rbd_img_object_requests()
6. another watch error occurs
7. rbd_watch_errcb() blocks trying to take lock_rwsem for write
8. I/O request 1 completion is received by the messenger but can't be
   processed because lock_rwsem won't be granted anymore
9. header read-in request completion can't be received, let alone
   processed, because the messenger is stranded

Change rbd_dev_refresh() to take header_rwsem only for actually
updating rbd_dev-&gt;header.  Header and parent info read-in don't need
any locking.

commit c10311776f0a8ddea2276df96e255625b07045a8 upstream.

Unlike header read-in, parent info read-in is already decoupled in
get_parent_info(), but it's buried in rbd_dev_v2_parent_info() along
with the processing logic.

Separate the initial read-in and update read-in logic into
rbd_dev_setup_parent() and rbd_dev_update_parent() respectively and
have rbd_dev_v2_parent_info() just populate struct parent_image_info
(i.e. what get_parent_info() did).  Some existing QoI issues, like
flatten of a standalone clone being disregarded on refresh, remain.

commit 510a7330c82a7754d5df0117a8589e8a539067c7 upstream.

Make rbd_dev_header_info() populate a passed struct rbd_image_header
instead of rbd_dev-&gt;header and introduce rbd_dev_update_header() for
updating mutable fields in rbd_dev-&gt;header upon refresh.  The initial
read-in of both mutable and immutable fields in rbd_dev_image_probe()
passes in rbd_dev-&gt;header so no update step is required there.

rbd_init_layout() is now called directly from rbd_dev_image_probe()
instead of individually in format 1 and format 2 implementations.

<title>drm/amd/display: fix the ability to use lower resolution modes on eDP</title>

commit 2de19022c5d7ff519dd5b9690f7713267bd1abfe upstream.

On eDP we can receive invalid modes from dm_update_crtc_state() for
entirely new streams for which drm_mode_set_crtcinfo() shouldn't be
called on. So, instead of calling drm_mode_set_crtcinfo() from within
create_stream_for_sink() we can instead call it from
amdgpu_dm_connector_mode_valid(). Since, we are guaranteed to only call
drm_mode_set_crtcinfo() for valid modes from that function (invalid
modes are rejected by that callback) and that is the only user
of create_validate_stream_for_sink() that we need to call
drm_mode_set_crtcinfo() for (as before commit cb841d27b876
("drm/amd/display: Always pass connector_state to stream validation"),
that is the only place where create_validate_stream_for_sink()'s
dm_state was NULL).

commit dc77721ea4aa1e8937e2436f230b5a69065cc508 upstream.

I had the following weird phenomena on a mobile phone: while
the capacity in /sys/class/power_supply/ab8500_fg/capacity
would reflect the actual charge and capacity of the battery,
only 1/3 of the value was shown on the battery status
indicator and warnings for low battery appeared.

It turns out that UPower, the Freedesktop power daemon,
will average all the power supplies of type "battery" in
/sys/class/power_supply/* if there is more than one battery.

For the AB8500, there was "battery" ab8500_fg, ab8500_btemp
and ab8500_chargalg. The latter two don't know anything
about the battery, and should not be considered. They were
however averaged and with the capacity of 0.

Flag ab8500_btemp and ab8500_chargalg with type "unknown"
so they are not averaged as batteries.

Remove the technology prop from ab8500_btemp as well, all
it does is snoop in on knowledge from another supply.

After this the battery indicator shows the right value.

commit dc77721ea4aa1e8937e2436f230b5a69065cc508 upstream.

I had the following weird phenomena on a mobile phone: while
the capacity in /sys/class/power_supply/ab8500_fg/capacity
would reflect the actual charge and capacity of the battery,
only 1/3 of the value was shown on the battery status
indicator and warnings for low battery appeared.

It turns out that UPower, the Freedesktop power daemon,
will average all the power supplies of type "battery" in
/sys/class/power_supply/* if there is more than one battery.

For the AB8500, there was "battery" ab8500_fg, ab8500_btemp
and ab8500_chargalg. The latter two don't know anything
about the battery, and should not be considered. They were
however averaged and with the capacity of 0.

Flag ab8500_btemp and ab8500_chargalg with type "unknown"
so they are not averaged as batteries.

Remove the technology prop from ab8500_btemp as well, all
it does is snoop in on knowledge from another supply.

After this the battery indicator shows the right value.

commit cbcdfbf5a6cd66e47e5ee5d49c4c5a27a07ba082 upstream.

Similar to the rk817 codec alias that was missing, the rk817 charger
driver is missing a module alias as well. This absence prevents the
driver from autoprobing on OF systems when it is built as a module.

Add the right MODULE_ALIAS to fix this.

<title>drm/i915/gt: Fix reservation address in ggtt_reserve_guc_top</title>

commit b7599d241778d0b10cdf7a5c755aa7db9b83250c upstream.

There is an assertion in ggtt_reserve_guc_top that the global GTT
is of size at least GUC_GGTT_TOP, which is not the case on a 32-bit
platform; see commit 562d55d991b39ce376c492df2f7890fd6a541ffc
("drm/i915/bdw: Only use 2g GGTT for 32b platforms"). If GEM_BUG_ON
is enabled, this triggers a BUG(); if GEM_BUG_ON is disabled, the
subsequent reservation fails and the driver fails to initialise
the device:

i915 0000:00:02.0: [drm:i915_init_ggtt [i915]] Failed to reserve top of GGTT for GuC
i915 0000:00:02.0: Device initialization failed (-28)
i915 0000:00:02.0: Please file a bug on drm/i915; see https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs for details.
i915: probe of 0000:00:02.0 failed with error -28

Make the reservation at the top of the available space, whatever
that is, instead of assuming that the top will be GUC_GGTT_TOP.
