User space verbs provider library would need chip context. Changing the ABI to add chip version details in structure. Furthermore, changing the kernel driver ucontext allocation code to initialize the abi structure with appropriate values. As suggested by community, appended the new fields at the bottom of the ABI structure and retaining to older fields as those were in the older versions. Keeping the ABI version at 1 and adding a new field in the ucontext response structure to hold the component mask. The user space library should check pre-defined flags to figure out if a certain feature is supported on not.

The driver uses mmap_sem for both pinned_vm accounting and get_user_pages(). Because rdma drivers might want to use gup_longterm() in the future we still need some sort of mmap_sem serialization (as opposed to removing it entirely by using gup_fast()). Now that pinned_vm is atomic the writer lock can therefore be converted to reader. This also fixes a bug that __qib_get_user_pages was not taking into account the current value of pinned_vm.

Taking a sleeping lock to _only_ increment a variable is quite the overkill, and pretty much all users do this. Furthermore, some drivers (ie: infiniband and scif) that need pinned semantics can go to quite some trouble to actually delay via workqueue (un)accounting for pinned pages when not possible to acquire it. By making the counter atomic we no longer need to hold the mmap_sem and can simply some code around it for pinned_vm users. The counter is 64-bit such that we need not worry about overflows such as rdma user input controlled from userspace.

A soft iwarp driver that uses the host TCP stack via a kernel mode socket does not need port mapping. In fact, if the port map daemon, iwpmd, is running, then iwpmd must not try and create/bind a socket to the actual port for a soft iwarp connection, since the driver already has that socket bound. Yet if the soft iwarp driver wants to interoperate with hard iwarp devices that -are- using port mapping, then the soft iwarp driver's mappings still need to be maintained and advertised by the iwpm protocol. This patch enhances the rdma driver<->iwcm interface to allow an iwarp driver to specify that it does not want port mapping. The iwpm kernel<->iwpmd interface is also enhanced to pass up this information on map requests. Care is taken to interoperate with the current iwpmd version (ABI version 3) and only use the new NL attributes if iwpmd supports ABI version 4. The ABI version define has also been created in rdma_netlink.h so both kernel and user code can share it. The iwcm and iwpmd negotiate the ABI version to use with a new HELLO netlink message.

In order to add new IWPM_NL attributes, the enums for the IWPM commands attributes are refactored such that a new attribute can be added without breaking ABI version 3. Instead of sharing nl attribute enums for both request and response messages, we create separate enums for each IWPM message request and reply. This allows us to extend any given IWPM message by adding new attributes for just that message. These new enums are created, though, in a way to avoid breaking ABI version 3.
