[ Upstream commit 43cbd64b1fdc1da89abdad88a022d9e87a98e9c6 ]
usnic has a modified version of the core codes' ib_umem_get() and
related, and the copy misses many of the bug fixes done over the years:
Commit bc3e53f682d9 ("mm: distinguish between mlocked and pinned pages")
Commit 87773dd56d54 ("IB: ib_umem_release() should decrement mm->pinned_vm
from ib_umem_get")
Commit 8494057ab5e4 ("IB/uverbs: Prevent integer overflow in ib_umem_get
address arithmetic")
Commit 8abaae62f3fd ("IB/core: disallow registering 0-sized memory region")
Commit 66578b0b2f69 ("IB/core: don't disallow registering region starting
at 0x0")
Commit 53376fedb9da ("RDMA/core: not to set page dirty bit if it's already
set.")
Commit 8e907ed48827 ("IB/umem: Use the correct mm during ib_umem_release")

Allow interval trees to quickly check for overlaps to avoid unnecesary
tree lookups in interval_tree_iter_first().
As of this patch, all interval tree flavors will require using a
'rb_root_cached' such that we can have the leftmost node easily
available. While most users will make use of this feature, those with
special functions (in addition to the generic insert, delete, search
calls) will avoid using the cached option as they can do funky things
with insertions -- for example, vma_interval_tree_insert_after().

The usnic_verbs kernel module was clearly marked with the following in
its code:
MODULE_LICENSE("Dual BSD/GPL");
However, we accidentally left a few clauses of the BSD text out of the
license header in all the source files. This commit fixes that: all
the files are properly dual BSD/GPL-licensed. Contributors that might
have been confused by this have been contacted to get their permission
and are Cc:ed here.

This adds a driver that allows userspace to use UD-like QPs over a
proprietary Cisco transport with Cisco's Virtual Interface Cards (VICs),
including VIC 1240 and 1280 cards.
