usnic_uiom_get_pages() uses gup_longterm() so we cannot really get rid of
mmap_sem altogether in the driver, but we can get rid of some complexity
that mmap_sem brings with only pinned_vm.  We can get rid of the wq
altogether as we no longer need to defer work to unpin pages as the
counter is now atomic. We also share the lock.

This driver already uses gup_fast() and thus we can just drop the mmap_sem
protection around the pinned_vm counter. Note that the window between when
hfi1_can_pin_pages() is called and the actual counter is incremented
remains the same as mmap_sem was _only_ used for when ->pinned_vm was
touched.

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 the reset process, we will release the resources firstly, and after the
hardware reset is completed, we will reapply resources and reconfigure the
hardware.

We can solve this problem by modifying both the NIC and the RoCE
driver. We can modify the concurrent processing in the NIC driver to avoid
calling the .reset_notify and .uninit_instance ops at the same time. And
we need to modify the RoCE driver to record the reset stage and the
driver's init/uninit state, and check the state in the .reset_notify,
.init_instance. and uninit_instance functions to avoid NULL pointer
operation.
