Pull SCSI scatter-gather list updates from James Bottomley: "This topic branch covers a fundamental change in how our sg lists are allocated to make mq more efficient by reducing the size of the preallocated sg list. This necessitates a large number of driver changes because the previous guarantee that if a driver specified SG_ALL as the size of its scatter list, it would get a non-chained list and didn't need to bother with scatterlist iterators is now broken and every driver *must* use scatterlist iterators.

2019-07-11Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsiLinus Torvalds113-8517/+5156
Pull SCSI updates from James Bottomley: "This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs, mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the removal of the osst driver (I heard from Willem privately that he would like the driver removed because all his test hardware has failed). Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...

In mlx5e_setup_tc "priv" variable is not being used if CONFIG_MLX5_ESWITCH is off, one way to fix this is to actually use it. mlx5e_setup_tc_mqprio also needs the "priv" variable and it extracts it on its own. We can simply pass priv to mlx5e_setup_tc_mqprio instead of netdev and avoid extracting the priv var, which will also resolve the compiler warning.

A dynamic formatting is issued whenever a write request returns with either a No Record Found error (Command Mode), Incorrect Length error (Transport Mode), or File Protected error (Transport Mode). All three cases mean that the tracks in question haven't been initialized in a desired format yet. The part of the volume that was tried to be written on is then formatted and the original request is re-queued. As the formatting will happen during normal I/O operations, it is quite likely that there won't be any memory available to build the respective request. Another two pages of memory are allocated per volume specifically for the dynamic formatting. The dasd_eckd_build_format() function is extended to make sure that the original startdev is reused. Also, all formatting and format check functions use the new memory pool exclusively now to reduce complexity. Read operations will always return zero data when unformatted areas are read.

These information are made accessible via internal functions for subsequent users, and via sysfs attributes for userpsace usage.

2019-07-11s390/dasd: Make layout analysis ESE compatibleJan Höppner1-6/+6
The disk layout and volume information of a DASD reside in the first two tracks of cylinder 0. When a DASD is set online, currently the first three tracks are read and analysed to confirm an expected layout. For CDL (Compatible Disk Layout) only count area data of the first track is evaluated and checked against expected key and data lengths. For LDL (Linux Disk Layout) the first and third track is evaluated. However, an LDL formatted volume is expected to be in the same format across all tracks. Checking the third track therefore doesn't have any more value than checking any other track at random. Now, an Extent Space Efficient (ESE) DASD is initialised by only formatting the first two tracks, as those tracks always contain all information necessarry. Checking the third track on an ESE volume will therefore most likely fail with a record not found error, as the third track will be empty. This in turn leads to the device being recognised with a volume size of 0. Attempts to write volume information on the first two tracks then fail with "no space left on device" errors. Initialising the first three tracks for an ESE volume is not a viable solution, because the third track is already a regular track and could contain user data. With that there is potential for data corruption. Instead, always only analyse the first two tracks, as it is sufficiant for both CDL and LDL, and allow ESE volumes to be recognised as well.

The TI K3 AM65x and J721E family of SoCs have a new Mailbox IP that is based on the existing Mailbox IP present in OMAP architecture based SoCs. Each instance of the legacy OMAP Mailbox IP is now a single cluster within the newer Mailbox IP instance on K3 architecture based SoCs. A single K3 Mailbox IP instance has multiple clusters with each cluster providing the same functionality as the existing OMAP Mailbox IP. Reuse the existing OMAP Mailbox driver to extend the support for this newer IP present within the Main NavSS block on K3 SoCs. The K3 family of SoCs use 64-bit ARMv8 processors for running Linux, so the driver is also enhanced to deal with the differences between the 32-bit message payloads and the 64-bit pointers used by the client drivers.
