This comment has been present since the start of git. Since no one is going to do anything about it, and all seems to work well, just drop the thing entirely.

The USB OTG code has the ability to disable external hubs, but the configuration option for it is oddly named. Rename it to be more obvious as to what it does.

Mediatek's LTE modem needs up to 8 ports to connect to PC for logging and debugging under some scenarios. Hence we suggest to increase the definition of MAX_U_SERIAL_PORTS to 8 for some complex embedded systems.

Several newer USB Device classes are not presently reported individually at /sys/kernel/debug/usb/devices, (reported as "unk."). This patch adds the following classes: 0fh (Personal Healthcare devices), 10h (USB Type-C combined Audio/Video devices) 11h (USB billboard), 12h (USB Type-C Bridge).

2020-06-14security: Add LSM hooks to set*gid syscallsThomas Cedeno5-1/+40
The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba4-166/+169
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

2020-06-14net: ethernet: ti: ale: fix allmulti for nu type aleGrygorii Strashko1-9/+40
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().
