Drivers that do not provide kernel verbs support should not be used by ib
kernel clients at all.
In case a device does not implement all mandatory verbs for kverbs usage
mark it as a non kverbs provider and prevent its usage for all clients
except for uverbs.
The device is marked as a non kverbs provider using the 'kverbs_provider'
flag which should only be set by the core code. The clients can choose
whether kverbs are requested for its usage using the 'no_kverbs_req' flag
which is currently set for uverbs only.
This patch allows drivers to remove mandatory verbs stubs and simply set
the callbacks to NULL. The IB device will be registered as a non-kverbs
provider. Note that verbs that are required for the device registration
process must be implemented.

Merge branch 'devx-async' into k.o/for-next
Yishai Hadas says:
Enable DEVX asynchronous query commands
This series enables querying a DEVX object in an asynchronous mode.
The userspace application won't block when calling the firmware and it will be
able to get the response back once that it will be ready.
To enable the above functionality:
- DEVX asynchronous command completion FD object was introduced.
- The applicable file operations were implemented to enable using it by
the user application.
- Query asynchronous method was added to the DEVX object, it will call the
firmware asynchronously and manages the response on the given input FD.
- Hot unplug support was added for the FD to work properly upon
unbind/disassociate.
- mlx5 core fence for asynchronous commands was implemented and used to
prevent racing upon unbind/disassociate.
This branch is based on mlx5-next & v5.0-rc2 due to dependencies, from

AtomicOp requests will be enabled only if the completer and all

PCI atomic operations on the device.
PCI atomic operations were first introduced in PCI Express Base Specification
2.1. The Supported operations are Swap (Unconditional Swap), CAS (Compare and

Unlike other atomic operation modes PCI atomic operations gives the user

RDMA/bnxt_re: fix a size calculation
This is from static analysis not from testing. Depending on the value
of rcfw->cmdq_depth, then this might not cause an issue at runtime.
The BITS_TO_LONGS() macro tells us how many longs it take to hold a
bitmap. In other words, it divides by the number if bits per long and
rounds up. Then we want to take that number and multiple by
sizeof(long) to get the number of bytes to allocate.
The code here does the multiplication first so the rounding up is done
in the wrong place. So imagine we want to allocate 1 bit, then
"(1 * 8) / 64 = 1" when we round up. But it should be
"(1 / 64) * 8 = 8". In other words, because of the rounding difference
we might allocate up to "sizeof(long) - 1" bytes fewer than intended.

phy: fix build breakage: add PHY_MODE_SATA
Commit
49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

Pull dma_zalloc_coherent() removal from Christoph Hellwig:
"We've always had a weird situation around dma_zalloc_coherent. To
safely support mapping the allocations to userspace major
architectures like x86 and arm have always zeroed allocations from
dma_alloc_coherent, but a couple other architectures were missing that
zeroing either always or in corner cases.
Then later we grew anothe dma_zalloc_coherent interface to explicitly
request zeroing, but that just added __GFP_ZERO to the allocation
flags, which for some allocators that didn't end up using the page
allocator ended up being a no-op and still not zeroing the
allocations.
So for this merge window I fixed up all remaining architectures to
zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
no-op wrapper around dma_alloc_coherent, which fixes all of the above
issues.
dma_zalloc_coherent is now pointless and can go away, and Luis helped

ata: ahci: mvebu: add Armada 3700 initialization needed for S2RAM
A3700 comphy initialization is done in the firmware (TF-A). Looking at
the SATA PHY initialization routine, there is a comment about "vendor
specific" registers. Two registers are mentioned. They are not
initialized there in the firmware because they are AHCI related, while
the firmware at this location does only PHY configuration. The
solution to avoid doing such initialization is relying on U-Boot.
While this work at boot time, U-Boot is definitely not going to run
during a resume after suspending to RAM.
Two possible solutions were considered:
* Fixing the firmware.
* Fixing the kernel driver.
The first solution would take ages to propagate, while the second
solution is easy to implement as the driver as been a little bit
reworked to prepare for such platform configuration. Hence, this patch
adds an Armada 3700 configuration function to set these two registers
both at boot time (in the probe) and after a suspend (in the resume
path).

15d3ce7b63bd ("ata: ahci_mvebu: add
support for Armada 3700 variant") introduced Armada 3700 support. As
opposed to Armada 38x SoCs, the 3700 variants do not have to configure
mbus and the regret option. This patch took care of avoiding such
configuration when not needed in the probe function, but failed to do
the same in the resume path. While doing so looks harmless by
experience, let's clean the driver logic and avoid doing this useless
configuration with Armada 3700 SoCs.
Because the logic is very similar between these two places, it has
been decided to factorize this code and put it in a "Armada 38x
configuration function". This function is part of a new
(per-compatible) platform data structure, so that the addition of such
configuration function for Armada 3700 will be eased.

Current implementation of the libahci does not take into account the

phy_set_mode() before phy_power_on().
PHYs should also be handled at suspend/resume time. For this, call
ahci_platform_enable/disable_phys() at suspend/resume_host() time. These
calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of
