git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma fixes from Doug Ledford: "Fourth set of -rc fixes for 4.13 cycle. This is all of the -rc fixes that we know of. I suspect this will be the last rc pull request, but you never know, I could be wrong. Nothing major here. There are the i40iw patches I mentioned in my last pull request minus one that I pulled out because it wasn't a fix and not appropriate for the rc cycle. Then a few other items trickled in and were added to the pull request. It's fairly small aside from those five i40iw patches - Set of five i40iw fixes (the first of these is rather large by line count consideration, but I decided to send it because if fixes a legitimate issue and the line count is because it does so by creating a new function and using it where needed instead of just patching up a few lines...a smaller fix could probably be done, but the larger fix is the better code solution) - One vmw_pvrdma fix - One hns_roce fix (this silences a checker warning, but can't actually happen, I expect a patch to remove this from all drivers that share this same check in for-next) - One iw_cxgb4 fix - Two IB core fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: IB/uverbs: Fix NULL pointer dereference during device removal IB/core: Protect sysfs entry on ib_unregister_device iw_cxgb4: fix misuse of integer variable IB/hns: fix memory leak on ah on error return path i40iw: Fix potential fcn_id_array out of bounds i40iw: Use correct alignment for CQ0 memory i40iw: Fix typecast of tcp_seq_num i40iw: Correct variable names i40iw: Fix parsing of query/commit FPM buffers RDMA/vmw_pvrdma: Report CQ missed events

2017-08-18RDMA/bnxt_re: Allocate multiple notification queuesSelvin Xavier
Enables multiple Interrupt vectors. Driver is requesting the max MSIX vectors based on the number of online cpus and creates upto 9 MSIx vectors (1 for control path and 8 for data path). A tasklet is created for each of these vectors. NQs are assigned to CQs in round robin fashion. This patch also adds IRQ affinity hint for the MSIX vector of each NQ.

2017-08-18PCI/IB: add support for pci driver attribute groupsGreg Kroah-Hartman
Some drivers (specifically the nes IB driver), want to create a lot of sysfs driver attributes. Instead of open-coding the creation and removal of these files (and getting it wrong btw), it's a better idea to let the driver core handle all of this logic for us. So add a new field to the pci driver structure, **groups, that allows pci drivers to specify an attribute group list it wishes to have created when it is registered with the driver core. Big bonus is now the driver doesn't race with userspace when the sysfs files are created vs. when the kobject is announced, so any script/tool that actually wanted to use these files will not have to poll waiting for them to show up.

Using the existing 't' hotkey, support the three views: percent, total period and number of samples on the annotate TUI browser, circulating them like below: Percent -> Total Period -> Nr Samples -> Percent ... Committer notes: Removed new 'e' hotkey, should be resubmitted as a separate patch, with proper justification for its inclusion.

2017-08-18blk-mq-pci: add a fallback when pci_irq_get_affinity returns NULLChristoph Hellwig
While pci_irq_get_affinity should never fail for SMP kernel that implement the affinity mapping, it will always return NULL in the UP case, so provide a fallback mapping of all queues to CPU 0 in that case.

2017-08-18perf annotate stdio: Support --show-nr-samples optionTaeung Song
Add --show-nr-samples option to "perf annotate" so that it matches "perf report". Committer note: Note that it can't be used together with --show-total-period, which seems like a silly limitation, that can be lifted at some point. Made it bail out if not on --stdio.
