Unfortunately, event running time, percentage and noise data are printed
in different positions in normal output than CSV/JSON. I think it's
better to put such details in where it actually prints.
So add before_metric argument to print_noise() and print_running() and
call them twice before and after the metric.

In the printout() function, it checks if the event is bad (i.e. not
counted or not supported) and print the result. But it does the same
what abs_printout() is doing. So add an argument to indicate the value
is ok or not and use the same function in both cases.

Commit 30de14b1884b ("s390: current_stack_pointer shouldn't be a
function") made current_stack_pointer a global register variable like
on many other architectures. Unfortunately on s390 it uncovers old
gcc bug which is fixed only since gcc-9.1 [gcc commit 3ad7fed1cc87
("S/390: Fix PR89775. Stackpointer save/restore instructions removed")]
and backported to gcc-8.4 and later. Due to this bug gcc versions prior
to 8.4 generate broken code which leads to stack corruptions.
Current minimal gcc version required to build the kernel is declared
as 5.1. It is not possible to fix all old gcc versions, so work
around this problem by avoiding using global register variable for
current_stack_pointer.

After the rework from commit 1ebe2e5f9d68 ("block: remove
GENHD_FL_EXT_DEVT"), when calling device_add_disk(), dcssblk will end up
in disk_scan_partitions(), and not break out early w/o GENHD_FL_NO_PART.
This will trigger implicit open/release via blkdev_get/put_whole()
later. dcssblk_release() will then deadlock on dcssblk_devices_sem
semaphore, which is already held from dcssblk_add_store() when calling
device_add_disk().
dcssblk does not support partitions (DCSSBLK_MINORS_PER_DISK == 1), and
never scanned partitions before. Therefore restore the previous
behavior, and explicitly disallow partition scanning by setting the
GENHD_FL_NO_PART flag. This will also prevent this deadlock scenario.

A problem about insmod thunderbolt-net failed is triggered with following
log given while lsmod does not show thunderbolt_net:
insmod: ERROR: could not insert module thunderbolt-net.ko: File exists
The reason is that tbnet_init() returns tb_register_service_driver()
directly without checking its return value, if tb_register_service_driver()
failed, it returns without removing property directory, resulting the
property directory can never be created later.

Yoga laptops
Commit 3ae86d2d4704 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock
LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops
to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam
interrupts until the laptop is rebooted.
Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to
manually set the LED on models on this list.

When an IO error occurs, the function __zonefs_io_error() is used to
issue a zone report to obtain the latest zone information from the
device. This function gets a zone report for all zones used as storage
for a file, which is always 1 zone except for files representing
aggregated conventional zones.
The number of zones of a zone report for a file is calculated in
__zonefs_io_error() by doing a bit-shift of the inode i_zone_size field,
which is equal to or larger than the device zone size. However, this
calculation does not take into account that the last zone of a zoned
device may be smaller than the zone size reported by bdev_zone_sectors()
(which is used to set the bit shift size). As a result, if an error
occurs for an IO targetting such last smaller zone, the zone report will
ask for 0 zones, leading to an invalid zone report.
Fix this by using the fact that all files require a 1 zone report,
except if the inode i_zone_size field indicates a zone size larger than
the device zone size. This exception case corresponds to a mount with
aggregated conventional zones.
A check for this exception is added to the file inode initialization
during mount. If an invalid setup is detected, emit an error and fail
the mount (check contributed by Johannes Thumshirn).

In the initial commit dc452a471dba ("net: dsa: introduce tagger-owned
storage for private and shared data"), we had a call to
tag_ops->disconnect(dst) issued from dsa_tree_free(), which is called at
tree teardown time.
There were problems with connecting to a switch tree as a whole, so this
got reworked to connecting to individual switches within the tree. In
this process, tag_ops->disconnect(ds) was made to be called only from
switch.c (cross-chip notifiers emitted as a result of dynamic tag proto
changes), but the normal driver teardown code path wasn't replaced with
anything.
Solve this problem by adding a function that does the opposite of
dsa_switch_setup_tag_protocol(), which is called from the equivalent
spot in dsa_switch_teardown(). The positioning here also ensures that we
won't have any use-after-free in tagging protocol (*rcv) ops, since the
teardown sequence is as follows:
dsa_tree_teardown
-> dsa_tree_teardown_master
-> dsa_master_teardown
-> unsets master->dsa_ptr, making no further packets match the
ETH_P_XDSA packet type handler
-> dsa_tree_teardown_ports
-> dsa_port_teardown
-> dsa_slave_destroy
-> unregisters DSA net devices, there is even a synchronize_net()
in unregister_netdevice_many()
-> dsa_tree_teardown_switches
-> dsa_switch_teardown
-> dsa_switch_teardown_tag_protocol
-> finally frees the tagger-owned storage

- The maths in the unlock loop is dodgy as it could, theoretically,

Current dual mode adaptor ("DP++") detection code assumes that all
adaptors support i2c sub-addressing for read operations from the
DP-HDMI adaptor ID buffer. It has been observed that multiple
adaptors do not in fact support this, and always return data starting
at register 0. On affected adaptors, the code fails to read the proper
registers that would identify the device as a type 2 adaptor, and
handles those as type 1, limiting the TMDS clock to 165MHz, even if
the according register would announce a higher TMDS clock.
Fix this by always reading the ID buffer starting from offset 0, and
discarding any bytes before the actual offset of interest.
We tried finding authoritative documentation on whether or not this is
allowed behaviour, but since all the official VESA docs are paywalled,
the best we could come up with was the spec sheet for Texas Instruments'
SNx5DP149 chip family.[1] It explicitly mentions that sub-addressing is
supported for register writes, but *not* for reads (See NOTE in
section 8.5.3). Unless TI openly decided to violate the VESA spec, one
could take that as a hint that sub-addressing is in fact not mandated
by VESA.
The other two adaptors affected used the PS8409(A) and the LT8611,
according to the data returned from their ID buffers.

The workaround designed for some specific ASICs is wrongly applied
to SMU13 ASICs. That leads to some runpm hang.

If we enable virtual display functionality on parts with
no display hardware we can end up trying to check for and
reserve the vbios FB area on devices where it doesn't exist.
Check if display hardware is actually present on the hardware
before trying to reserve the memory.
v2: move the check into common code

It is to resolve a regression, which fails to allocate
VRAM due to no free memory in application, the reason
is we add check of vram_pin_size for memory limit, and
application is pinning the memory for Peerdirect, KFD
should not count it in memory limit. So removing
vram_pin_size will resolve it.

DM maps DRM CRTC degamma to DPP (pre-blending) degamma block, but DCE doesn't
support programmable degamma curve anywhere. Currently, a custom degamma is
accepted by DM but just ignored by DCE driver and degamma correction isn't
actually applied. There is no way to map custom degamma in DCE, therefore, DRM
CRTC degamma property shouldn't be enabled for DCE drivers.

[WHY?]
Max number of lines that can be used for prefetch due to type constraints is
63.75.
[HOW?]
Enforce maximum prefetch lines as 63.75.

[WHY?]
DCN32 uses fclk pstate watermarks for dummy pstate, and must always be
supported.
[HOW?]
Validation needs to be run with fclk pstate latency set
as the dummy pstate latency to get correct prefetch and bandwidth outputs.

[Why]
dcn314 uses optc2_configure_crc() that wraps
optc1_configure_crc() + set additional registers
not applicable to dcn314.
It's not critical but when used leads to warning like:
WARNING: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c
Call Trace:

[Why]
The cursor size (in memory) is currently incorrectly calculated,
resulting not enough CAB being allocated for static screen cursor
in MALL refresh. This results in cursor image corruption.
[How]
Use cursor pitch instead of cursor width when calculating cursor size.
Update num cache lines calculation to use the result of the cursor size
calculation instead of manually recalculating again.

This reverts commit 981f09295687f856d5345e19c7084aca481c1395.
It turns out this causes logically active but disconnected DP MST
connectors to disappear from the KMS resources list, and Mutter
then assumes the connector is already disabled. Later on Mutter tries
to re-use the same CRTC but fails since on the kernel side it's still
tied to the disconnected DP MST connector.

[Why]
For DCN3.2 and DCN3.21, VBIOS has switch to using v3.0 of the VRAM
info struct. We should read and override the VRAM info in driver with
values provided by VBIOS to support memory downbin cases.
