2022-11-16perf stat: Split print_noise_pct() functionNamhyung Kim
Likewise, split print_noise_pct() for each output mode. Although it's a tiny function, more logic will be added soon so it'd be better split it and treat it in the same way.

2022-11-16s390: avoid using global register for current_stack_pointerVasily Gorbik
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.

2022-11-16s390/dcssblk: fix deadlock when adding a DCSSGerald Schaefer
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.

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.

2022-11-16zonefs: fix zone report size in __zonefs_io_error()Damien Le Moal
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).

2022-11-15net: dsa: don't leak tagger-owned storage on switch driver unbindVladimir Oltean
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 Fixes: 7f2973149c22 ("net: dsa: make tagging protocols connect to individual switches from a tree") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Saeed Mahameed <saeed@kernel.org> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Link: https://lore.kernel.org/r/20221114143551.1906361-1-vladimir.oltean@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-11-15drm/display: Don't assume dual mode adaptors support i2c sub-addressingSimon Rettberg
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.

2022-11-15drm/amd/display: don't enable DRM CRTC degamma property for DCEMelissa Wen
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.

2022-11-15Revert "drm: hide unregistered connectors from GETCONNECTOR IOCTL"Simon Ser
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.
