Parav Pandit ea4baf7f11 RDMA: Rename port_callback to init_port
Most provider routines are callback routines which ib core invokes.
_callback suffix doesn't convey information about when such callback is
invoked. Therefore, rename port_callback to init_port.

Additionally, store the init_port function pointer in ib_device_ops, so
that it can be accessed in subsequent patches when binding rdma device to
net namespace.

Jason Gunthorpe b0ea0fa543 IB/{core,hw}: Have ib_umem_get extract the ib_ucontext from ib_udata
ib_umem_get() can only be called in a method callback, which always has a
udata parameter. This allows ib_umem_get() to derive the ucontext pointer
directly from the udata without requiring the drivers to find it in some
way or another.

Shamir Rabinovitch 6fa8f1afd3 IB/{core,uverbs}: Move ib_umem_xxx functions from ib_core to ib_uverbs
The next patch will add dependency from ib_umem_get in to ib_uverbs so
move the required ib_umem_xxx functionality to it's correct module -
ib_uverbs - and avoid circular dependecy from the form of ib_core ->
ib_uverbs -> ib_core in depmod.

Since this now requires all drivers to be build modular if uverbs is
modular, hoist the test a couple drivers had into the main kconfig and
apply it to all drivers uniformly.

Gustavo A. R. Silva 7a7b0fea6f IB/srp: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.
