Add a devlink parameter to control the number of large groups in a
autogrouped flow table. The default value is 15, and the range is between 1
and 1024.
The size of each large group can be calculated according to the following
formula: size = 4M / (fdb_large_groups + 1).
Examples:
- Set the number of large groups to 20.
$ devlink dev param set pci/0000:82:00.0 name fdb_large_groups \
cmode driverinit value 20
Then run devlink reload command to apply the new value.
$ devlink dev reload pci/0000:82:00.0
- Read the number of large groups in flow table.
$ devlink dev param show pci/0000:82:00.0 name fdb_large_groups
pci/0000:82:00.0:
name fdb_large_groups type driver-specific
values:
cmode driverinit value 20

Propagate the resolved link parameters via the mac_link_up() call for
MACs that do not automatically track their PCS state. We propagate the
link parameters via function arguments so that inappropriate members
of struct phylink_link_state can't be accessed, and creating a new

This sentence does not make sense in the section about mandatory-y.
This seems to be a copy-paste mistake of commit fcc8487d47 ("uapi:

The correct description would be "The convention is to list one
mandatory-y per line ...".
I just removed it instead of fixing it. If such information is needed,

When there was no parallelism (no top-level -j arg and a pre-1.7

Special handling is needed in bareudp module for IP & MPLS as they
support more than one ethertypes.
MPLS has 2 ethertypes. 0x8847 for MPLS unicast and 0x8848 for MPLS multicast.
While decapsulating MPLS packet from UDP packet the tunnel destination IP
address is checked to determine the ethertype. The ethertype of the packet
will be set to 0x8848 if the tunnel destination IP address is a multicast
IP address. The ethertype of the packet will be set to 0x8847 if the
tunnel destination IP address is a unicast IP address.
IP has 2 ethertypes.0x0800 for IPV4 and 0x86dd for IPv6. The version
field of the IP header tunnelled will be checked to determine the ethertype.
This special handling to tunnel additional ethertypes will be disabled
by default and can be enabled using a flag called multiproto. This flag can
be used only with ethertypes 0x8847 and 0x0800.

Pull arm64 fixes from Will Deacon:
"It's all straightforward apart from the changes to mmap()/mremap() in
relation to their handling of address arguments from userspace with
non-zero tag bits in the upper byte.
The change to brk() is necessary to fix a nasty user-visible
regression in malloc(), but we tightened up mmap() and mremap() at the
same time because they also allow the user to create virtual aliases
by accident. It's much less likely than brk() to matter in practice,
but enforcing the principle of "don't permit the creation of mappings
using tagged addresses" leads to a straightforward ABI without having
to worry about the "but what if a crazy program did foo?" aspect of
things.
Summary:
- Fix regression in malloc() caused by ignored address tags in brk()
- Add missing brackets around argument to untagged_addr() macro
- Fix clang build when using binutils assembler
- Fix silly typo in virtual memory map documentation"

Add append value operator "+=" support to bootconfig syntax.
With this operator, user can add new value to the key as
an entry of array instead of overwriting.
For example,
foo = bar
...
foo += baz
Then the key "foo" has "bar" and "baz" values as an array.

Currently, bootconfig adds a new value on the existing key to the tail of an
array. But this looks a bit confusing because an admin can easily rewrite
the original value in the same config file.
This rejects the following value re-definition.
key = value1
...
key = value2
You should rewrite value1 to value2 in this case.

parent key node.
A value node can not co-exist with subkey node under some key
node, e.g.

key.subkey = another-value
This is not be allowed because bootconfig API is not designed
to handle such case.

Add bootconfig magic word to the end of bootconfig on initrd
image for indicating explicitly the bootconfig is there.
Also tools/bootconfig treats wrong size or wrong checksum or
parse error as an error, because if there is a bootconfig magic
word, there must be a bootconfig.
The bootconfig magic word is "#BOOTCONFIG\n", 12 bytes word.
Thus the block image of the initrd file with bootconfig is
as follows.
[Initrd][bootconfig][size][csum][#BOOTCONFIG\n]

Currently the arm64 kernel ignores the top address byte passed to brk(),
mmap() and mremap(). When the user is not aware of the 56-bit address
limit or relies on the kernel to return an error, untagging such
pointers has the potential to create address aliases in user-space.
Passing a tagged address to munmap(), madvise() is permitted since the
tagged pointer is expected to be inside an existing mapping.
The current behaviour breaks the existing glibc malloc() implementation
which relies on brk() with an address beyond 56-bit to be rejected by
the kernel.
Remove untagging in the above functions by partially reverting commit
ce18d171cb ("mm: untag user pointers in mmap/munmap/mremap/brk"). In
addition, update the arm64 tagged-address-abi.rst document accordingly.

Commit 1de243b076 ("media: dt-bindings: media: sun4i-csi: Add compatible
for CSI1 on A10/A20") introduced support for the CSI1 controller on A10 and
A20 that unlike CSI0 doesn't have an ISP and therefore only have two
clocks, the bus and module clocks.
The clocks and clock-names properties have thus been modified to allow
either two or tree clocks. However, the current list has the ISP clock at
the second position, which means the bindings expects a list of either
bus and isp, or bus, isp and mod. The initial intent of the patch was
obviously to have bus and mod in the former case.
Let's fix the binding so that it validates properly.
