This patch implements the srq specific verbs such as create/destroy/modify
and post_srq_recv. And adds srq specific structures and defines to t4.h
and uapi.
Also updates the cq poll logic to deal with completions that are
associated with the SRQ's.
This patch also handles kernel mode SRQ_LIMIT events as well as flushed
SRQ buffers

We have a parallel unlocked reader and writer with ib_uverbs_get_context()
vs everything else, and nothing guarantees this works properly.
Audit and fix all of the places that access ucontext to use one of the
following locking schemes:
- Call ib_uverbs_get_ucontext() under SRCU and check for failure
- Access the ucontext through an struct ib_uobject context member
while holding a READ or WRITE lock on the uobject.
This value cannot be NULL and has no race.
- Hold the ucontext_lock and check for ufile->ucontext !NULL
This also re-implements ib_uverbs_get_ucontext() in a way that is safe
against concurrent ib_uverbs_get_context() and disassociation.
As a side effect, every access to ucontext in the commands is via
ib_uverbs_get_context() with an error check, or via the uobject, so there
is no longer any need for the core code to check ucontext on every command
call. These checks are also removed.

This approach matches the standard flow of the typical write method that
relies on the HW object to store the device and the uobject to access the
ucontext. Avoids the use of the devx_ufile2uctx in several places will
make revising the semantics of ib_uverbs_get_ucontext() in the next patch
simpler.

Allocating the struct file during alloc_begin creates this strange
asymmetry with IDR, where the FD has two krefs pointing at it during the
pre-commit phase. In particular this makes the abort process for FD very
strange and confusing.
For instance abort currently calls the type's destroy_object twice, and
the fops release once if abort is done. This is very counter intuitive. No
fops should be called until alloc_commit succeeds, and destroy_object
should only ever be called once.
Moving the struct file allocation to the alloc_commit is now simple, as we
already support failure of rdma_alloc_commit_uobject, with all the
required rollback pieces.
This creates an understandable symmetry with IDR and simplifies/fixes the
abort handling for FD types.

The ioctl framework already does this correctly, but the write path did
not. This is trivially fixed by simply using a standard pattern to return
uobj_alloc_commit() as the last statement in every function.

The locking here has always been a bit crazy and spread out, upon some
careful analysis we can simplify things.
Create a single function uverbs_destroy_ufile_hw() that internally handles
all locking. This pulls together pieces of this process that were
sprinkled all over the places into one place, and covers them with one
lock.
This eliminates several duplicate/confusing locks and makes the control
flow in ib_uverbs_close() and ib_uverbs_free_hw_resources() extremely
simple.
Unfortunately we have to keep an extra mutex, ucontext_lock. This lock is
logically part of the rwsem and provides the 'down write, fail if write
locked, wait if read locked' semantic we require.

Rename 'cleanup_rwsem' to 'hw_destroy_rwsem' which is held across any call
to the type destroy function (aka 'hw' destroy). The main purpose of this
lock is to prevent normal add and destroy from running concurrently with
uverbs_cleanup_ufile()
Since the uobjects list is always manipulated under the 'hw_destroy_rwsem'
we can eliminate the uobjects_lock in the cleanup function. This allows
converting that lock to a very simple spinlock with a narrow critical
section.

The locking requirements here have changed slightly now that we can rely
on the ib_uverbs_file always existing and containing all the necessary
locking infrastructure.
That means we can get rid of the cleanup_mutex usage (this was protecting
the check on !uboj->context).
Otherwise, follow the same pattern that IDR uses for destroy, acquire
exclusive write access, then call destroy and the undo the 'lookup'.

This wasn't wrong, but the placement of two krefs didn't make any
sense. Follow some simple rules.
- A kref is held inside uobjects_list
- A kref is held inside the IDR
- A kref is held inside file->private
- A stack based kref is passed bettwen alloc_begin and
alloc_abort/alloc_commit
Any place we destroy one of the above pointers, we stick a put,
or 'move' the kref into another pointer.
The key functions have sensible semantics:
- alloc_uobj fully initializes the common members in uobj, including
the list
- Get rid of the uverbs_idr_remove_uobj helper since IDR remove
does require put, but it depends on the situation. Later
patches will re-consolidate this differently.
- alloc_abort always consumes the passed kref, done in the type
- alloc_commit always consumes the passed kref, done in the type
- rdma_remove_commit_uobject always pairs with a lookup_get
After it is all done the only control flow change is to:
- move a get from alloc_commit_fd_uobject to rdma_alloc_commit_uobject
- add a put to remove_commit_idr_uobject
- Consistenly use rdma_lookup_put in rdma_remove_commit_uobject at
the right place

The alloc_commit callback makes the uobj visible to other threads,
and it does so using a 'move' semantic of the uobj kref on the stack
into the public storage (eg the IDR, uobject list and file_private_data)
Once this is done another thread could start up and trigger deletion
of the kref. Fortunately cleanup_rwsem happens to prevent this from
being a bug, but that is a fantastically unclear side effect.
Re-organize things so that alloc_commit is that last thing to touch
the uobj, get rid of the sneaky implicit dependency on cleanup_rwsem,
and add a comment reminding that uobj is no longer kref'd after
alloc_commit.

Our ABI for write() uses a s32 for FDs and a u32 for IDRs, but internally
we ended up implicitly casting these ABI values into an 'int'. For ioctl()
we use a s64 for FDs and a u64 for IDRs, again casting to an int.
The various casts to int are all missing range checks which can cause
userspace values that should be considered invalid to be accepted.
Fix this by making the generic lookup routine accept a s64, which does not
truncate the write API's u32/s32 or the ioctl API's s64. Then push the
detailed range checking down to the actual type implementations to be
shared by both interfaces.
Finally, change the copy of the uobj->id to sign extend into a s64, so eg,
if we ever wish to return a negative value for a FD it is carried
properly.
This ensures that userspace values are never weirdly interpreted due to
the various trunctations and everything that is really out of range gets
an EINVAL.

This is because the type was replaced with the null_type during explicit
destroy that cannot complete the destruction.
One of the side effects of replacing the type is to make the object
handle totally unreachable - so no other command could attempt to use
it, even though it remains on the uboject list.
We can get the same end result by just fully destroying the object inside
rdma_explicit_destroy and leaving the caller the residual kref for the
uobj with no attached HW object, and no presence in the ubojects list.

According to "Annex A16: RDMA over Converged Ethernet (RoCE)":
A16.4.3 MANAGEMENT INTERFACES
As defined in the base specification, a special Queue Pair, QP0 is defined
solely for communication between subnet manager(s) and subnet management
agents. Since such an IB-defined subnet management architecture is outside
the scope of this annex, it follows that there is also no requirement that
a port which conforms to this annex be associated with a QP0. Thus, for
end nodes designed to conform to this annex, the concept of QP0 is
undefined and unused for any port connected to an Ethernet network.
CA16-8: A packet arriving at a RoCE port containing a BTH with the
destination QP field set to QP0 shall be silently dropped.
