| * IB/qedr: Remove GID add/del dummy routinesParav Pandit2018-04-033-39/+0
| | | | | | | | | | | | | | | | | | | | | | | | qedr driver's add_gid() and del_gid() callbacks are doing simple checks which are already done by the ib core before invoking these callback routines. Therefore, code is simplified to skip implementing add_gid() and del_gid() callback functions. Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

| * IB/uverbs: Extend uverbs_ioctl header with driver_idMatan Barak2018-03-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Extending uverbs_ioctl header with driver_id and another reserved field. driver_id should be used in order to identify the driver. Since every driver could have its own parsing tree, this is necessary for strace support. Downstream patches take off the EXPERIMENTAL flag from the ioctl() IB support and thus we add some reserved fields for future usage.

| * RDMA/qedr: eliminate duplicate barriers on weakly-ordered archsSinan Kaya2018-03-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Code includes wmb() followed by writel() in multiple places. writel() already has a barrier on some architectures like arm64. This ends up CPU observing two barriers back to back before executing the register write. Since code already has an explicit barrier call, changing writel() to writel_relaxed().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Once the FW is transitioned to error, FLUSH cqes can be received.

Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for.

In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly.
