A subesequent patch will use the same workqueue for executing other
work not related to control VQ. Rename the workqueue and the work queue
entry used to convey information to the workqueue.

No need to save the mtu int the net device struct. We can save it in the
config struct which cannot be modified.
Moreover, move the initialization to. mlx5_vdpa_set_features() callback
is not the right place to put it.

This patch adds a new vDPA driver for Alibaba ENI(Elastic Network

And this driver is only enabled on X86 host currently.

For the devices which implement the get_vq_num_min callback, the driver
should not negotiate with virtqueue size with the backend vdpa device if
the value returned by get_vq_num_min equals to the value returned by
get_vq_num_max.
This is useful for vdpa devices based on legacy virtio specfication.

Sometimes a user would like to control the amount of request queues to
be created for a block device. For example, for limiting the memory

No need to pre-allocate a big buffer for the IO SGL anymore. If a device
has lots of deep queues, preallocation for the sg list can consume
substantial amounts of memory. For HW virtio-blk device, nr_hw_queues
can be 64 or 128 and each queue's depth might be 128. This means the
resulting preallocation for the data SGLs is big.
Switch to runtime allocation for SGL for lists longer than 2 entries.
This is the approach used by NVMe drivers so it should be reasonable for
virtio block as well. Runtime SGL allocation has always been the case
for the legacy I/O path so this is nothing new.
The preallocated small SGL depends on SG_CHAIN so if the ARCH doesn't
support SG_CHAIN, use only runtime allocation for the SGL.
Re-organize the setup of the IO request to fit the new sg chain
mechanism.
No performance degradation was seen (fio libaio engine with 16 jobs and
128 iodepth):

The Chrome EC's features are returned through an
ec_response_get_features struct, but they are stored in an independent
array. Although the two are effectively the same at present (2 unsigned
32 bit ints), there is the possibility that they could go out of sync.
Avoid this by only using the EC struct to store the features.

KVM/arm64 updates for Linux 5.16
- More progress on the protected VM front, now with the full
fixed feature set as well as the limitation of some hypercalls
after initialisation.
- Cleanup of the RAZ/WI sysreg handling, which was pointlessly
complicated
- Fixes for the vgic placement in the IPA space, together with a
bunch of selftests
- More memcg accounting of the memory allocated on behalf of a guest
- Timer and vgic selftests
- Workarounds for the Apple M1 broken vgic implementation
- KConfig cleanups
- New kvmarm.mode=none option, for those who really dislike us

Commit 1bdb542da736 ("drm/ingenic: Simplify code by using hwdescs
array") caused the dma_hwdesc_phys_f{0,1} variables to be used while
uninitialized in a mmio register write, which most certainly broke the
ingenic-drm driver.
However, the very same patchset also submitted commit 6055466203df
("drm/ingenic: Upload palette before frame"), which restored a correct
behaviour by doing the register writes in a different place in the code.
What's left of this, is just to remove the bogus register writes in the
probe function.

The Host Performance Buffer feature allows UFS read commands to carry the
physical media addresses along with the LBAs, thus allowing less internal
L2P-table switches in the device. HPB1.0 allowed a single LBA, while
HPB2.0 increases this capacity up to 255 blocks.
Carrying more than a single record, the read operation is no longer purely
of type "read" but a "hybrid" command: Writing the physical address to the
device in one operation and reading back the required payload in another.
The JEDEC HPB spec defines two commands for this operation:
HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and
HPB-READ to read the payload.
With the current HPB design the UFS driver has no alternative but to divide
the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ.
This causes a great deal of aggravation to the block layer guys who
demanded that we completely revert the entire HPB driver regardless of the
huge amount of corporate effort already invested in it.
As a compromise, remove only the pieces that implement the 2.0
specification. This is done as a matter of urgency for the final 5.15
release.

USB transfer buffers are typically mapped for DMA and must not be
allocated on the stack or transfers will fail.
Allocate proper transfer buffers in the various command helpers and
return an error on short transfers instead of acting on random stack
data.
Note that this also fixes a stack info leak on systems where DMA is not
used as 32 bytes are always sent to the device regardless of how short

There is only one bnxt ULP in the upstream kernel and definition
for other ULP can be safely removed.

Like i.MX8 SCU, i.MX8ULP S4 also has vendor specific protocol.
- bind SCU/S4 MU part to share one tx/rx/init API to make code simple.
- S4 msg max size is very large, so alloc the space at driver probe,
not use local on stack variable.
- S4 MU has 8 TR and 4 RR which is different with i.MX8 MU, so adapt
code to reflect this.
Tested on i.MX8MP, i.MX8ULP

Move the PCCT subspace parsing and allocation into pcc_mbox_probe so
that we can get rid of global PCC channel and mailbox controller data.
It also helps to make use of devm_* APIs for all the allocations.

With all the plumbing in place to avoid accessing PCCT type and other
fields directly from the PCCT table all the time, let us now add the
support for extended PCC subspaces(type 3 and 4).

pcc_chan_reg_init now checks if the register bit width is within the
list [8, 16, 32, 64] and flags error if that is not the case. Therefore
there is no need to handling invalid bit-width in both read_register
and write_register. We can drop that along with the return values for
these 2 functions.

Now that the con_priv is availvale solely for PCC mailbox controller
driver, let us use the same to save the channel specific information
in it so that we can it whenever required instead of parsing the PCCT
table entries every time in both pcc_send_data and pcc_mbox_irq.
We can now use the newly introduces PCC register bundle to simplify both
saving of channel specific information and accessing them without repeated
checks for the subspace type.

Extended PCC subspaces introduces more registers into the PCCT. In order
to consolidate access to these registers and to keep all the details
contained in one place, let us introduce PCC register bundle that holds
the ACPI Generic Address Structure as well as the virtual address for
the same if it is mapped in the OS.
It also contains the various masks used to access the register and
the associated read, write and read-modify-write accessors.
We can also clean up the initialisations by having a helper function
for the same.

The specification refers this register and associated bitmask as platform
interrupt acknowledge register. Let us rename it so that it is easier to
map and understand.

Now that we have all the shared memory region information populated in
the pcc_mbox_chan, let us propagate the pointer to the same as the
return value to pcc_mbox_request channel.
This eliminates the need for the individual users of PCC mailbox to
parse the PCCT subspace entries and fetch the shmem information. This
also eliminates the need for PCC mailbox controller to set con_priv to
PCCT subspace entries. This is required as con_priv is private to the
controller driver to attach private data associated with the channel and
not meant to be used by the mailbox client/users.
Let us convert all the users of pcc_mbox_{request,free}_channel to use
new interface.
