Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver
already supports reflection on the Y axis via a custom flag which is not
very useful because it requires custom userspace. Add the standard
rotation property that supports 0 degree rotation and Y axis reflection
for primary and overlay planes to provide a better interface than the
custom flag.

====================
NFP eBPF JIT is missing logic indirect shifts (both left and right) and
arithmetic right shift (both indirect shift and shift by constant).
This patch adds support for them.
For indirect shifts, shift amount is not specified as constant, NFP needs
to get the shift amount through the low 5 bits of source A operand in
PREV_ALU, therefore extra instructions are needed compared with shifts by
constants.
Because NFP is 32-bit, so we are using register pair for 64-bit shifts and
therefore would need different instruction sequences depending on whether
shift amount is less than 32 or not.
NFP branch-on-bit-test instruction emitter is added by this patch set and
is used for efficient runtime check on shift amount. We'd think the shift
amount is less than 32 if bit 5 is clear and greater or equal then 32
otherwise. Shift amount is greater than or equal to 64 will result in
undefined behavior.
This patch also use range info to avoid generating unnecessary runtime code
if we are certain shift amount is less than 32 or not.

Code logic is similar with arithmetic right shift by constant, and NFP
get indirect shift amount through source A operand of PREV_ALU.
It is possible to fall back to logic right shift if the MSB is known to be
zero from range info, however there is no benefit to do this given logic
indirect right shift use the same number and cycle of instruction sequence.
Suppose the MSB of regX is the bit we want to replicate to fill in all the
vacant positions, and regY contains the shift amount, then we could use
single instruction to set up both.

Sites may wish to provide additional metadata alongside files in order
to make more fine-grained security decisions[1]. The security of this is
enhanced if this metadata is protected, something that EVM makes
possible. However, the kernel cannot know about the set of extended
attributes that local admins may wish to protect, and hardcoding this
policy in the kernel makes it difficult to change over time and less
convenient for distributions to enable.
This patch adds a new /sys/kernel/security/integrity/evm/evm_xattrs node,
which can be read to obtain the current set of EVM-protected extended
attributes or written to in order to add new entries. Extending this list
will not change the validity of any existing signatures provided that the
file in question does not have any of the additional extended attributes -
missing xattrs are skipped when calculating the EVM hash.
[1] For instance, a package manager could install information about the
package uploader in an additional extended attribute. Local LSM policy
could then be associated with that extended attribute in order to
restrict the privileges available to packages from less trusted
uploaders.

In case CONFIG_HSA_AMD is not chosen, there is no need to compile amdkfd
files that reside inside amdgpu dirver. In addition, because amdkfd
depends on x86_64 architecture and amdgpu is not, compiling amdkfd files
under i386 architecture can cause compiler errors and warnings.
This patch modifies amdgpu's makefile to build amdkfd files only if
CONFIG_HSA_AMD is chosen. The only file to be compiled unconditionally
is amdgpu_amdkfd.c
There are stub functions that are compiled only if amdkfd is not
compiled. In that case, calls from amdgpu driver proper will go to those
functions instead of the real functions.
v2: instead of using function pointers, use stub functions

When run raidconfig from Dom0 we found that the Xen DMA heap is reduced,
but Dom Heap is increased by the same size. Tracing raidconfig we found
that the related ioctl() in megaraid_sas will call dma_alloc_coherent()
to apply memory. If the memory allocated by Dom0 is not in the DMA area,
it will exchange memory with Xen to meet the requiment. Later drivers
call dma_free_coherent() to free the memory, on xen_swiotlb_free_coherent()
the check condition (dev_addr + size - 1 <= dma_mask) is always false,
it prevents calling xen_destroy_contiguous_region() to return the memory
to the Xen DMA heap.

This patch changes the function smc_buf_free to use the SMC link group
instead of the link as function parameter. Also, it changes the order of
the other two parameters.

This patch moves a CDC sanity check from smc_cdc_msg_recv_action() to
the other sanity checks in smc_cdc_rx_handler(). While doing this, it
simplifies smc_cdc_msg_recv() and removes unneeded function parameters.

SMC connection and buffer handling belong to smc_core. So, this patch

Currently, the write offset within the RMB is calculated on each write
operation although it is fixed for each connection. With this patch, the
offset is calculated once and stored in a connection specific variable.

This patch moves the global link group list to smc_core where the link
group functions are. To make this work, it moves code in af_smc and
smc_ib that operates on the link group list to smc_core as well.
While at it, the link group counter is integrated into the list
structure and initialized to zero.

In addition to the buffer references, SMC currently stores the sizes of
the receive and send buffers in each connection as separate variables.
This patch introduces a buffer length variable in the common buffer
descriptor and uses this length instead.

This series addresses a regression introduced by the
shared block TC changes [1]. Currently, for VF->VF and uplink->VF rules, the
TC core (cls_api) attempts to offload the same flow multiple times into
the driver, as a side effect of the mlx5 registration to the egdev callback.
We use the flow cookie to ignore attempts to add such flows, we can't
reject them (return error), b/c this will fail the offload attempt, so we
ignore that.
The last patch of the series deals with exposing HW stats counters through
ethtool for the vport reps.
Dave - the regression that we are addressing was introduced in 4.15 [1] and applies
to nfp and mlx5. Jiri suggested to push driver side fixes to net-next, this is
already done for nfp [2][3]. Once this is upstream, we will submit a small/point
single patch fix for the TC core code which can serve for net and stable, but not
carried into net-next, b/c it might limit some future use-cases.

mlx5 core dirver updates for both net-next and rdma-next branches.
From Christophe JAILLET, first three patche to use kvfree where needed.
From: Or Gerlitz <ogerlitz@mellanox.com>
Next six patches from Roi and Co adds support for merged
sriov e-switch which comes to serve cases where both PFs, VFs set
on them and both uplinks are to be used in single v-switch SW model.
When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
This model allows to offload TC eswitch rules between VFs belonging
to different PFs (and hence have different eswitch affinity), it also
sets the some of the foundations needed for uplink LAG support.
