Return a device UAR index for a given user index via the DEVX interface.
Security note:
The hardware protection mechanism works like this: Each device object that
is subject to UAR doorbells (QP/SQ/CQ) gets a UAR ID (called uar_page in
the device specification manual) upon its creation. Then upon doorbell,
hardware fetches the object context for which the doorbell was rang, and
validates that the UAR through which the DB was rang matches the UAR ID
of the object.
If no match the doorbell is silently ignored by the hardware. Of
course, the user cannot ring a doorbell on a UAR that was not mapped to
it.
Now in devx, as the devx kernel does not manipulate the QP/SQ/CQ command
mailboxes (except tagging them with UID), we expose to the user its UAR
ID, so it can embed it in these objects in the expected specification
format. So the only thing the user can do is hurt itself by creating a
QP/SQ/CQ with a UAR ID other than his, and then in this case other users
may ring a doorbell on its objects.
The consequence of that will be that another user can schedule a QP/SQ
of the buggy user for execution (just insert it to the hardware schedule
queue or arm its CQ for event generation), no further harm is expected.

This patch replaces the ib_device_attr.max_sge with max_send_sge and
max_recv_sge. It allows ulps to take advantage of devices that have very
different send and recv sge depths. For example cxgb4 has a max_recv_sge
of 4, yet a max_send_sge of 16. Splitting out these attributes allows
much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW
API. Consider a large RDMA WRITE that has 16 scattergather entries.
With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of
16, it can be done with 1 WRITE WR.

Allocate agent IDs from a global IDR instead of an atomic variable.
This eliminates the possibility of reusing an ID which is already in
use after 4 billion registrations. We limit the assigned ID to be less
than 2^24 as the mlx4 driver uses the most significant byte of the agent
ID to store the slave number. Users unlucky enough to see a collision
between agent numbers and slave numbers see messages like:
mlx4_ib: egress mad has non-null tid msb:1 class:4 slave:0
and the MAD layer stops working.
We look up the agent under protection of the RCU lock, which means we
have to free the agent using kfree_rcu, and only increment the reference
counter if it is not 0.

In order to be able to expose pointers to the ib_gid_attrs in the GID
table we need to make it so the value of the pointer cannot be
changed. Thus each GID table entry gets a unique piece of kref'd memory
that is written only during initialization and remains constant for its
lifetime.
This eventually will allow the struct ib_gid_attrs to be returned without
copy from many of query the APIs, but it also provides a way to track when
all users of a HW table index go away.
For roce we no longer allow an in-use HW table index to be re-used for a
new an different entry. When a GID table entry needs to be removed it is
hidden from the find API, but remains as a valid HW index and all
ib_gid_attr points remain valid. The HW index is not relased until all
users put the kref.
Later patches will broadly replace the use of the sgid_index integer with
the kref'd structure.
Ultimately this will prevent security problems where the OS changes the
properties of a HW GID table entry while an active user object is still
using the entry.

Pull fsnotify updates from Jan Kara:
"fsnotify cleanups unifying handling of different watch types.
This is the shortened fsnotify series from Amir with the last five
patches pulled out. Amir has modified those patches to not change
struct inode but obviously it's too late for those to go into this
merge window"
