Pull CIFS updates from Steve French:
"The most visible change in this set is the additional of multi-credit
support for SMB2/SMB3 which dramatically improves the large file i/o
performance for these dialects and significantly increases the maximum
i/o size used on the wire for SMB2/SMB3.
Also reconnection behavior after network failure is improved"

No-one has yet had time to move this to debugfs as discussed during
the last merge window. Until this happens, hide the option to make
it clear it's not going to be here forever.

We have another version of it implemented in SW, however, that version
isn't serialised with normal PGRAPH operation and can possibly clobber
the enables for another context.
This is the same method that's implemented by the NVIDIA binary driver.

... and hope that the defaults are good enough. This was always
supposed to be a read/modify/write thing anyway, so we're writing
very wrong stuff for some boards already.

Should be the same values as before, except:
GF117 has smaller buffer allocated, as per register setup.
GK20A now uses values from Tegra driver, not GK104's.

Removes need for fixed buffer indices, and allows the functions
utilising them to also be run outside of context generation.

Default ZBC table is compatible with binary driver defaults.
Userspace will need to be updated to take full advantage of this
feature, however, some applications will see a performance boost
without updated drivers.

The full object interfaces are about to be exposed to userspace, so we
need to check for any security-related issues and version the structs
to make it easier to handle any changes we may need in the future.

One of the next commits will remove some of the class IDs, leaving only
the ones used by NVIDIA which, presumably, mark where functionality
changes actually happened.

The indirect method has been left in-place here as a fallback path, as
it may not be possible to map the non-PAGE_SIZE aligned control areas
across some chipset+interface combinations.
This isn't a problem for the primary use-case where the core and drm
are linked together in kernel-land, but across a VM or (in the case
where it applies now) between the core in the kernel and a userspace
test tool.

This is a wrapper around the interfaces defined in an earlier commit,
and is also used by various userspace (either by a libdrm backend, or
libpciaccess) tools/tests.
In the future this will be extended to handle channels, replacing some
long-unloved code we currently use, and allow fifo/display/mpeg (hi
Ilia ;)) engines to all be exposed in the same way.
