2017-11-03Update MIPS email addressesPaul Burton
MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list. An entry is added to .mailmap for each person such that get_maintainer.pl will report the new addresses rather than @imgtec.com addresses which will soon be dead. Instances of the affected addresses throughout the tree are then mechanically replaced with the new @mips.com address.

2017-11-03scsi: storvsc: Allow only one remove lun work item to be issued per lunCathy Avery
When running multipath on a VM if all available paths go down the driver can schedule large amounts of storvsc_remove_lun work items to the same lun. In response to the failing paths typically storvsc responds by taking host->scan_mutex and issuing a TUR per lun. If there has been heavy IO to the failed device all the failed IOs are returned from the host. A remove lun work item is issued per failed IO. If the outstanding TURs have not been completed in a timely manner the scan_mutex is never released or released too late. Consequently the many remove lun work items are not completed as scsi_remove_device also tries to take host->scan_mutex. This results in dragging the VM down and sometimes completely. This patch only allows one remove lun to be issued to a particular lun while it is an instantiated member of the scsi stack.

2017-11-03staging: fsl-dpaa2/eth: Extra headroom in RX buffersBogdan Purcareata
The needed headroom that we ask the stack to reserve for us in TX skbs is larger than the headroom available in RX frames, which leads to skb reallocations in forwarding scenarios involving two DPNI interfaces. Configure the hardware to reserve some extra space in the RX frame headroom to avoid this situation. The value is chosen based on the Tx frame data offset, the Rx buffer alignment value and the netdevice required headroom. The network stack will take care to reserve space for HH_DATA_MOD when building the skb, so there's no need to account for it in the netdevice needed headroom.

2017-11-03staging: lustre: ldlm: remove unnecessary 'ownlocks' variable.NeilBrown
Now that the code has been simplified, 'ownlocks' is not necessary. The loop which sets it exits with 'lock' having the same value as 'ownlocks', or pointing to the head of the list if ownlocks is NULL. The current code then tests ownlocks and sets 'lock' to exactly the value that it currently has. So discard 'ownlocks'. Also remove unnecessary initialization of 'lock'.

2017-11-03staging: lustre: ldlm: tidy list walking in ldlm_flock()NeilBrown
Use list_for_each_entry variants to avoid the explicit list_entry() calls. This allows us to use list_for_each_entry_safe_from() instread of adding a local list-walking macro. Also improve some comments so that it is more obvious that the locks are sorted per-owner and that we need to find the insertion point.
