2017-08-22IB/core: Fix input len in multiple user verbsAmrani, Ram
Most user verbs pass user data to the kernel with the inclusion of the ib_uverbs_cmd_hdr structure. This is problematic because the vendor has no ideas if the verb was called by a legacy verb or an extended verb. Also, the incosistency between the verbs is confusing.

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.
