05e6a5a635 RDMA/hns: Add CQ flag instead of independent enable flag
It's easier to understand and maintain enable flags of cq using a single
field in type of u32 than defining a field for every flags in the
structure hns_roce_cq, and we can add new flags for features more
conveniently in the future.

The hardware can truncate PI/CI when posting or polling, the driver does
not need to do truncation. Therefore keep the software's PI/CI consistent

677f1410e0 scripts/checkstack.pl: don't display $dre as different entity
currently script prints stack usage for functions
in two ways:($re and $dre)

dre breaks sorting mechanism.

..
0xffffa00011f27210 sunxi_divs_clk_setup [vmlinux]:      Dynamic (0x1d0)

so we can print it in decimal only.

Also address before function name is changed to function
start address rather than stack consumption address.
Because in next patch, arm has two ways to use stack
which can be clubbed and printed in one function only.

All symbols whose stack by adding(re and dre) is greater than
100, will be printed.

859c817501 modpost,fixdep: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

bcfefb61cd kconfig: announce removal of 'kvmconfig' and 'xenconfig' shorthands
kvmconfig' is a shorthand for kvm_guest.config to save 7 character typing.

xenconfig' is a shorthand for xen.config to save 1 character typing.

There is nothing more than that.

There are more files in kernel/configs/, so it is not maintainable
to wire-up every config fragment to the Kconfig Makefile. Hence,
we should not do this at all.

These will be removed after Linux 5.10. Meanwhile, the following
warning message will be displayed if they are used.

     "

after debug into spi-stm32 driver, st-gyro-spi split two steps to read
l3gd20 id

first: send command to l3gd20 with read id command in tx_buf, rx_buf
is null.
second: read id with tx_buf is null, rx_buf not null.

so, for second step, stm32 driver recongise this process as 'SPI_SIMPLE_RX'
from stm32_spi_communication_type(), but there is no related process for this
type in stm32f4_spi_set_mode(), then we get error from
stm32_spi_transfer_one_setup().

we can use two method to fix this bug.
1, use stm32 spi's "In unidirectional receive-only mode (BIDIMODE=0 and
RXONLY=1)". but as our code running in sdram, the read latency is too large
to get so many receive overrun error in interrupts handler.

2, use stm32 spi's "In full-duplex (BIDIMODE=0 and RXONLY=0)", as tx_buf is
null, so add flag 'SPI_MASTER_MUST_TX' to spi master.

Change since V4:
1 remove dummy data sent out by stm32 spi driver
2 add flag 'SPI_MASTER_MUST_TX' to spi master

f202272cab Merge series "ASoC: add soc-link" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:
Hi Mark

Current ALSA SoC is handling dai_link related operation,
but it is implmemented directly without using function/macro,
and at random place.

This v4 patch-set creates new snd_soc_link_xxx() functions
which handles dai_link related operation,
and implmement these at new soc-link.c.

v3 -> v4

	- add Reviewed-by from Ranjani and Pierre-Louis
	- fix bisection error at [2/7]

v2 -> v3

	- add missing #include <sound/soc-link.h> in soc-link.c

v1 -> v2
	- #include <sound/soc-link.h> is added on each c source file
	  instead of soc.h
	- not have extra error message after snd_soc_link_xxx(),
	  because it already indicate it via snc_link_ret()
	- snd_soc_link_compr_xxx() doesn't have rtd parameter,
	  because it can be created from cstream

3ca570da20 Merge series "ASoC: SOF: extended manifest support for 5.8" from Kai Vehmanen <kai.vehmanen@linux.intel.com>:
Hello,

extended firmware manifest is a method to retrieve capabilities
directly from the firmware file instead of routing the information via
the DSP and reading it back via IPC (latter mechanism still supported
but will be deprecated).

This feature was briefly merged to 5.8 with the series sent on
2020-Apr-15, but due to a regression hit with exporting uapi headers,
the patches got dropped.

Here's an update with the uapi header issue fixed, rebased to latest
'for-5.8' and a few minor fixes. This has been sitting in sof-dev for
some weeks and no further issues have been found. We also added
a check for the uapi-export case to SOF CI, so such errors would
not slip through again in the future.

Tooling support to create firmware files with an extended header
is available in SOF firmware repository (see the rimage tool) and
this part is already merged.

With dedicated power domain for asrc, power can be disabled after
probe and pm runtime suspend, then the value of all registers need to
be restored in pm runtime resume. So we can merge suspend/resume function
to runtime_suspend/resume function and enable regcache only in end of
probe.

ed17b8d377 xfrm: fix a warning in xfrm_policy_insert_list
This waring can be triggered simply by:

  # ip xfrm policy update src 192.168.1.1/24 dst 192.168.1.2/24 dir in \
    priority 1 mark 0 mask 0x10  #[1]
  # ip xfrm policy update src 192.168.1.1/24 dst 192.168.1.2/24 dir in \
    priority 2 mark 0 mask 0x1   #[2]
  # ip xfrm policy update src 192.168.1.1/24 dst 192.168.1.2/24 dir in \
    priority 2 mark 0 mask 0x10  #[3]

Then dmesg shows:

  [ ] WARNING: CPU: 1 PID: 7265 at net/xfrm/xfrm_policy.c:1548
  [ ] RIP: 0010:xfrm_policy_insert_list+0x2f2/0x1030

  [ ]  netlink_sendmsg+0x714/0xbf0
  [ ]  sock_sendmsg+0xe2/0x110

The issue was introduced by Commit 7cb8a93968 ("xfrm: Allow inserting
policies with matching mark and different priorities"). After that, the
policies [1] and [2] would be able to be added with different priorities.

However, policy [3] will actually match both [1] and [2]. Policy [1]
was matched due to the 1st 'return true' in xfrm_policy_mark_match(),
and policy [2] was matched due to the 2nd 'return true' in there. It
caused WARN_ON() in xfrm_policy_insert_list().

This patch is to fix it by only (the same value and priority) as the
same policy in xfrm_policy_mark_match().

Thanks to Yuehaibing, we could make this fix better.

v1->v2:
  - check policy->mark.v == pol->mark.v only without mask.
