There was a place holder for hca_type and vendor was returned
in hca_rev. Fix the hca_rev to return the hw revision and fix
the hca_type to return an informative string representing the
hca.

The specification for the Toeplitz function doesn't require to set the key
explicitly to be symmetric. In case a symmetric functionality is required
a symmetric key can be simply used.
Wrongly forcing the algorithm to symmetric causes the wrong packet
distribution and a performance degradation.

The device requires that memory registration work requests that update the
address translation table of a MR will be fenced if posted together. This
scenario can happen when address ranges are invalidated by the mmu in
separate concurrent calls to the invalidation callback.
We prefer to block concurrent address updates for a single MR over fencing
since making the decision if a WQE needs fencing will be more expensive
and fencing all WQEs is a too radical choice.
Further, it isn't clear that this code can even run safely concurrently,
so a lock is a safer choice.

Any dma map underlying the MR should only be freed once the MR is fenced
at the hardware.
As of the above we first destroy the MKEY and just after that can safely
call to dma_unmap_single().

Fix unreg_umr to move the MR to a kernel owned PD (i.e. the UMR PD) which
can't be accessed by userspace.
This ensures that nothing can continue to access the MR once it has been
placed in the kernels cache for reuse.
MRs in the cache continue to have their HW state, including DMA tables,
present. Even though the MR has been invalidated, changing the PD provides
an additional layer of protection against use of the MR.

Use a direct firmware command to destroy the mkey in case the unreg UMR
operation has failed.
This prevents a case that a mkey will leak out from the cache post a
failure to be destroyed by a UMR WR.
In case the MR cache limit didn't reach a call to add another entry to the
cache instead of the destroyed one is issued.
In addition, replaced a warn message to WARN_ON() as this flow is fatal
and can't happen unless some bug around.

When a TID sequence error occurs while receiving TID RDMA READ RESP
packets, all packets after flow->flow_state.r_next_psn should be dropped,
including those response packets for subsequent segments.
The current implementation will drop the subsequent response packets for
the segment to complete next, but may accept packets for subsequent
segments and therefore mistakenly advance the r_next_psn fields for the
corresponding software flows. This may result in failures to complete
subsequent segments after the current segment is completed.
The fix is to only use the flow pointed by req->clear_tail for checking
KDETH PSN instead of finding a flow from the request's flow array.

The field flow->resync_npkts is added for TID RDMA WRITE request and
zero-ed when a TID RDMA WRITE RESP packet is received by the requester.
This field is used to rewind a request during retry in the function
hfi1_tid_rdma_restart_req() shared by both TID RDMA WRITE and TID RDMA
READ requests. Therefore, when a TID RDMA READ request is retried, this
field may not be initialized at all, which causes the retry to start at an
incorrect psn, leading to the drop of the retry request by the responder.
This patch fixes the problem by zeroing out the field when the flow memory
is allocated.

When run perftest in many times, the system will report a BUG as follows:
BUG: Bad rss-counter state mm:(____ptrval____) idx:0 val:-1
BUG: Bad rss-counter state mm:(____ptrval____) idx:1 val:1
We tested with different kernel version and found it started from the the
following commit:
commit d10bcf947a3e ("RDMA/umem: Combine contiguous PAGE_SIZE regions in
SGEs")
In this commit, the sg->offset is always 0 when sg_set_page() is called in
ib_umem_get() and the drivers are not allowed to change the sgl, otherwise
it will get bad page descriptor when unfolding SGEs in __ib_umem_release()
as sg_page_count() will get wrong result while sgl->offset is not 0.
However, there is a weird sgl usage in the current hns driver, the driver
modified sg->offset after calling ib_umem_get(), which caused we iterate
past the wrong number of pages in for_each_sg_page iterator.
This patch fixes it by correcting the non-standard sgl usage found in the
hns_roce_db_map_user() function.

Pull ARM Devicetree updates from Olof Johansson:
"We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM
Mali GPU devices added to device trees, since the DRM drivers have now
been merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Fixes and polish for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now
at feature parity with TX1"

In the function alps_is_cs19_trackpoint(), we check if the param[1] is
in the 0x20~0x2f range, but the code we wrote for this checking is not
correct:
(param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f,
it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f...
Now fix it with a new condition checking ((param[1] & 0xf0) == 0x20).

The keyboard and trackpad on recent MacBook's (since 8,1) and
MacBookPro's (13,* and 14,*) are attached to an SPI controller instead
of USB, as previously. The higher level protocol is not publicly
documented and hence has been reverse engineered. As a consequence there
are still a number of unknown fields and commands. However, the known
parts have been working well and received extensive testing and use.
In order for this driver to work, the proper SPI drivers need to be
loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci;
for all others they are spi_pxa2xx_platform and intel_lpss_pci.

In nouveau_conn_reset(), if connector->state is true,
__drm_atomic_helper_connector_destroy_state() will be called,
but the memory pointed by asyc isn't freed. Memory leak happens
in the following function __drm_atomic_helper_connector_reset(),
where newly allocated asyc->state will be assigned to connector->state.
So using nouveau_conn_atomic_destroy_state() instead of
__drm_atomic_helper_connector_destroy_state to free the "old" asyc.
Here the is the log showing memory leak.

It turns out that while disabling i2c bus access from software when the
GPU is suspended was a step in the right direction with:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
We also ended up accidentally breaking the vbios init scripts on some
older Tesla GPUs, as apparently said scripts can actually use the i2c
bus. Since these scripts are executed before initializing any
subdevices, we end up failing to acquire access to the i2c bus which has
left a number of cards with their fan controllers uninitialized. Luckily
this doesn't break hardware - it just means the fan gets stuck at 100%.
This also means that we've always been using our i2c busses before
initializing them during the init scripts for older GPUs, we just didn't
notice it until we started preventing them from being used until init.
It's pretty impressive this never caused us any issues before!
So, fix this by initializing our i2c pad and busses during subdev
pre-init. We skip initializing aux busses during pre-init, as those are
guaranteed to only ever be used by nouveau for DP aux transactions.

Modesetting only, still waiting on ACR/GR firmware from NVIDIA for Turing
graphics/compute bring-up.
Each subsystem was compared with traces, along with various tests to check
that things generally work as they should, and appears compatible enough
with the current TU117 code to enable support.
