[ Upstream commit 071d583e01c88272f6ff216d4f867f8f35e94d7d ]
Having a limit of 64 DRM devices is not good enough for modern world
where we have multi-GPU servers, SR-IOV virtual functions and virtual
devices used for testing.
Let's utilize full minor range for DRM devices.
To avoid regressing the existing userspace, we're still maintaining the
numbering scheme where 0-63 is used for primary, 64-127 is reserved
(formerly for control) and 128-191 is used for render.
For minors >= 192, we're allocating minors dynamically on a first-come,
first-served basis.

Commit 82b74cac28 ("blk-ioprio: Convert from rqos policy to direct
call") pushed setting bio I/O priority down into blk_mq_submit_bio()
-- which is too low within block core's submit_bio() because it
skips setting I/O priority for block drivers that implement
fops->submit_bio() (e.g. DM, MD, etc).
Fix this by moving bio_set_ioprio() up from blk-mq.c to blk-core.c and
call it from submit_bio(). This ensures all block drivers call
bio_set_ioprio() during initial bio submission.

A Linux guest on Hyper-V gets the TSC frequency from a synthetic MSR, if
available. In this case, set X86_FEATURE_TSC_KNOWN_FREQ so that Linux
doesn't unnecessarily do refined TSC calibration when setting up the TSC
clocksource.
With this change, a message such as this is no longer output during boot
when the TSC is used as the clocksource:
[ 1.115141] tsc: Refined TSC clocksource calibration: 2918.408 MHz
Furthermore, the guest and host will have exactly the same view of the
TSC frequency, which is important for features such as the TSC deadline
timer that are emulated by the Hyper-V host.

[ Upstream commit 258905cb9a6414be5c9ca4aa20ef855f8dc894d4 ]
We use komeda_crtc_normalize_zpos to normalize zpos of affected planes
to their blending zorder in CU. If there's only one slave plane in
affected planes and its layer_split property is enabled, order++ for
its split layer, so that when calculating the normalized_zpos
of master planes, the split layer of the slave plane is included, but
the max_slave_zorder does not include the split layer and keep zero
because there's only one slave plane in affacted planes, although we
actually use two slave layers in this commit.
In most cases, this bug does not result in a commit failure, but assume
the following situation:
slave_layer 0: zpos = 0, layer split enabled, normalized_zpos =
0;(use slave_layer 2 as its split layer)
master_layer 0: zpos = 2, layer_split enabled, normalized_zpos =
2;(use master_layer 2 as its split layer)
master_layer 1: zpos = 4, normalized_zpos = 4;
master_layer 3: zpos = 5, normalized_zpos = 5;
kcrtc_st->max_slave_zorder = 0;
When we use master_layer 3 as a input of CU in function
komeda_compiz_set_input and check it with function
komeda_component_check_input, the parameter idx is equal to
normailzed_zpos minus max_slave_zorder, the value of idx is 5
and is euqal to CU's max_active_inputs, so that
komeda_component_check_input returns a -EINVAL value.
To fix the bug described above, when calculating the max_slave_zorder
with the layer_split enabled, count the split layer in this calculation
directly.

[ Upstream commit 094513f8a2fbddee51b055d8035f995551f98fce ]
When the firmware crashes, we first told the op_mode and only then,
changed the transport's state. This is a problem if the op_mode's
nic_error() handler needs to send a host command: it'll see that the
transport's state still reflects that the firmware is alive.
Today, this has no consequences since we set the STATUS_FW_ERROR bit and
that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording
looks at this bit to know not to send a host command for example.
To fix the hibernation, we needed to reset the firmware without having
an error and checking STATUS_FW_ERROR to see whether the firmware is
alive will no longer hold, so this change is necessary as well.
Change the flow a bit.
Change trans->state before calling the op_mode's nic_error() method and
check trans->state instead of STATUS_FW_ERROR. This will keep the
current behavior of iwl_fw_dbg_stop_restart_recording upon firmware
error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording
safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not
alive.

wait for TX queues to become empty after firmware died. Clearly,

Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some

of the code running even when the firmware is not running.
