This patch introduces userclock sysfs interfaces for AFU, user could use these interfaces for clock setting to AFU. Please note that, this is only working for port header feature with revision 0, for later revisions, userclock setting is moved to a separated private feature, so one revision sysfs interface is exposed to userspace application for this purpose too.

2019-09-03ice: Only disable VLAN pruning for the VF when all VLANs are removedBrett Creeley
Currently if the VF adds a VLAN, VLAN pruning will be enabled for that VSI. Also, when a VLAN gets deleted it will disable VLAN pruning even if other VLAN(s) exists for the VF. Fix this by only disabling VLAN pruning on the VF VSI when removing the last VF (i.e. vf->num_vlan == 0).

2019-09-03ice: Remove enable DCB when SW LLDP is activatedMichal Swiatkowski
Remove code that enables DCB in initialization when SW LLDP is activated. DCB flag is set or reset before in ice_init_pf_dcb based on number of TCs. So there is not need to overwrite it. Setting DCB without checking number of TCs can cause communication problems with other cards. Host card sends packet with VLAN priority tag, but client card doesn't strip this tag and ping doesn't work.

2019-09-03ice: Report what the user set for coalesce [tx|rx]-usecsBrett Creeley
Currently if the user sets an odd value for [tx|rx]-usecs we align the value because the hardware only understands ITR values in multiples of 2. This seems misleading because we are essentially telling the user that the ITR value is odd, when in fact we have changed it internally. Fix this by reporting that setting odd ITR values is not allowed. Also, while making changes to ice_set_rc_coalesce() I noticed a bit of code/error duplication.

2019-09-03md raid0/linear: Mark array as 'broken' and fail BIOs if a member is goneGuilherme G. Piccoli
Currently md raid0/linear are not provided with any mechanism to validate if an array member got removed or failed. The driver keeps sending BIOs regardless of the state of array members, and kernel shows state 'clean' in the 'array_state' sysfs attribute. This leads to the following situation: if a raid0/linear array member is removed and the array is mounted, some user writing to this array won't realize that errors are happening unless they check dmesg or perform one fsync per written file. Despite udev signaling the member device is gone, 'mdadm' cannot issue the STOP_ARRAY ioctl successfully, given the array is mounted. In other words, no -EIO is returned and writes (except direct ones) appear normal. Meaning the user might think the wrote data is correctly stored in the array, but instead garbage was written given that raid0 does stripping (and so, it requires all its members to be working in order to not corrupt data). For md/linear, writes to the available members will work fine, but if the writes go to the missing member(s), it'll cause a file corruption situation, whereas the portion of the writes to the missing devices aren't written effectively. This patch changes this behavior: we check if the block device's gendisk is UP when submitting the BIO to the array member, and if it isn't, we flag the md device as MD_BROKEN and fail subsequent I/Os to that device; a read request to the array requiring data from a valid member is still completed. While flagging the device as MD_BROKEN, we also show a rate-limited warning in the kernel log. A new array state 'broken' was added too: it mimics the state 'clean' in every aspect, being useful only to distinguish if the array has some member missing. We rely on the MD_BROKEN flag to put the array in the 'broken' state. This state cannot be written in 'array_state' as it just shows one or more members of the array are missing but acts like 'clean', it wouldn't make sense to write it. With this patch, the filesystem reacts much faster to the event of missing array member: after some I/O errors, ext4 for instance aborts the journal and prevents corruption. Without this change, we're able to keep writing in the disk and after a machine reboot, e2fsck shows some severe fs errors that demand fixing. This patch was tested in ext4 and xfs filesystems, and requires a 'mdadm' counterpart to handle the 'broken' state.

2019-09-03coresight: tmc-etr: Add barrier packets when moving offset forwardMathieu Poirier
This patch adds barrier packets in the trace stream when the offset in the data buffer needs to be moved forward. Otherwise the decoder isn't aware of the break in the stream and can't synchronise itself with the trace data.
