All refcount operations are protected by spinlocks now.
Then the atomic counter can be replaced by a normal int.
This patch depends on PATCH 1/2.

The atomic_dec_and_test() is not safe because it is
outside of locks.
Move the locks of t4_smte_free() to its caller,
cxgb4_smt_release() to protect the atomic decrement.

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;
struct boo entry[];
};
instance = kvzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

Introduce SMT operations for allocating/removing entries from
SMAC table. Make TCAM filters use the SMT ops whenever SMAC rewrite
is required.
