The current IRQ handler clears all the IRQ status bits when it bails
out. This is dangerous because it might clear away the status bits
that have just been set while processing the current handler. If this
happens, the IRQ event for the latest transfer is lost forever.

The IRQ status bits must be cleared *before* the next transfer is
kicked.

Currently, a timeout error could happen at a repeated START condition.

For a (non-repeated) START condition, the controller starts sending
data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated
START condition, the hardware starts running when the slave address is
written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is
actually unneeded.

Because the hardware is already running before the IRQ is enabled for
a repeated START, the driver may miss the IRQ event. In most cases,
this problem does not show up since modern CPUs are much faster than
the I2C transfer. However, it is still possible that a context switch
happens after the controller starts, but before the IRQ register is
set up.

To fix this,

 - Do not write UNIPHIER_FI2C_CR for repeated START conditions.

 - Enable IRQ *before* writing the slave address to the TX FIFO.

 - Disable IRQ for the current CPU while queuing up the TX FIFO;
   If the CPU is interrupted by some task, the interrupt handler
   might be invoked due to the empty TX FIFO before completing the
   setup.

This is unlikely to happen, but it is possible for a CPU to enter
the interrupt handler just after wait_for_completion_timeout() has
expired. If this happens, the hardware is accessed from multiple
contexts concurrently.

Disable the IRQ after wait_for_completion_timeout(), and do nothing
from the handler when the IRQ is disabled.

Commit 1ff2e1a4 ("HID: input: Create a utility class for counting
scroll events") created the helper function

    hid_scroll_counter_handle_scroll()

to handle high-res scroll events and also expose them as regular wheel
events.

But the resulting algorithm was unstable, and causes scrolling to be
very unreliable.  When you hit the half-way mark of the highres
multiplier, small highres movements will incorrectly translate into big
traditional wheel movements, causing odd jitters.

Simplify the code and make the output stable.

NOTE! I'm pretty sure this will need further tweaking.  But this at
least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
a usable one.

Arnd acks, and adds the following notes:
 "I did a thorough review of the ABI, which as usual mainly consists of
  spotting any files that don't use the asm-generic ABI itself, and
  having it changed to it matches exactly what we do on other new
  architectures.

  I also looked at every other patch and commented on maybe half of them
  where I saw something that did not quite seem right. Others have
  reviewed specific patches in greater depth. I'm sure that one could
  fine more of the minor details, but as long as they are not ABI
  relevant, they can be fixed later.

  The only patch that is part of the ABI and that nobody reviewed is the
  signal handling. This is one of the areas I never worked on in much
  detail. I did not see anything wrong with it, but I also don't know
  what the problems with the other architectures are here, and we seem
  to be hitting issues occasionally, and we never managed to generalize
  this enough for new architectures to have a trivial implementation.

  I was originally hoping that we could have the 64-bit time_t
  interfaces ready in time to completely drop the 32-bit ones, but that
  did not happen. We might still remove them in the next merge window
  depending on whether the libc upstream people prefer to keep them or
  not.

  One more general comment: I think this may well be the last new CPU
  architecture we ever add to the kernel. Both nds32 and c-sky are made
  by companies that also work on risc-v, and generally speaking risc-v
  seems to be killing off any of the minor licensable instruction set
  projects, just like ARM has mostly killed off the custom
  vendor-specific instruction sets already.

  If we add another architecture in the future, it may instead be
  something like the LLVM bitcode or WebAssembly, who knows?"

To which Geert Uytterhoeven pipes in about another architecture still in
the pipeline: Kalray MPPA.

Since its inception, udp_dump_one has had a bug where userspace
needs to swap src and dst addresses and ports in order to find
the socket it wants. This is because it passes the socket source
address to __udp[46]_lib_lookup's saddr argument, but those
functions are intended to find local sockets matching received
packets, so saddr is the remote address, not the local address.

This can no longer be fixed for backwards compatibility reasons,
so add a brief comment explaining that this is the case. This
will avoid confusion and help ensure SOCK_DIAG implementations
of new protocols don't have the same problem.

macsec: linkstate fixes

This series fixes issues with handling administrative and operstate of
macsec devices.

Radu Rendec proposed another version of the first patch [0] but I'd
rather not follow the behavior of vlan devices, going with macvlan
does instead. Patrick Talbert also reported the same issue to me.

The second patch is a follow-up. The restriction on setting the device
up is a bit unreasonable, and operstate provides the information we
need in this case.

Currently, the kernel doesn't let the administrator set a macsec device
up unless its lower device is currently up. This is inconsistent, as a
macsec device that is up won't automatically go down when its lower
device goes down.

Now that linkstate propagation works, there's really no reason for this
limitation, so let's remove it.

Like all other virtual devices (macvlan, vlan), the operstate of a
macsec device should match the state of its lower device. This is done
by calling netif_stacked_transfer_operstate from its netdevice notifier.

We also need to call netif_stacked_transfer_operstate when a new macsec
device is created, so that its operstate is set properly. This is only
relevant when we try to bring the device up directly when we create it.

Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
that included changing the administrative state of the macsec device,
instead of just the operstate. This version is similar to what the
macvlan driver does, and updates only the operstate.

passed netlink validation and was a valid struct tc_gred_sopt...).

Recently a check was added which prevents marking of routers with zero
source address, but for IPv6 that cannot happen as the relevant RFCs
actually forbid such packets:
RFC 2710 (MLDv1):
"To be valid, the Query message MUST
 come from a link-local IPv6 Source Address, be at least 24 octets
 long, and have a correct MLD checksum."

Same goes for RFC 3810.

And also it can be seen as a requirement in ipv6_mc_check_mld_query()
which is used by the bridge to validate the message before processing
it. Thus any queries with :: source address won't be processed anyway.
So just remove the check for zero IPv6 source address from the query
processing function.

Fixes: 5a2de63f ("bridge: do not add port to router list when receives query with source 0.0.0.0")

Pull XArray conversion from Matthew Wilcox:
 "The XArray provides an improved interface to the radix tree data
  structure, providing locking as part of the API, specifying GFP flags
  at allocation time, eliminating preloading, less re-walking the tree,
  more efficient iterations and not exposing RCU-protected pointers to
  its users.

  This patch set

   1. Introduces the XArray implementation

   2. Converts the pagecache to use it

   3. Converts memremap to use it

  The page cache is the most complex and important user of the radix
  tree, so converting it was most important. Converting the memremap
  code removes the only other user of the multiorder code, which allows
  us to remove the radix tree code that supported it.

  I have 40+ followup patches to convert many other users of the radix
  tree over to the XArray, but I'd like to get this part in first. The
  other conversions haven't been in linux-next and aren't suitable for
  applying yet, but you can see them in the xarray-conv branch if you're
  interested"

Create DEF_FIELD_ADDR_VAR as a more generic version of the DEF_FIELD_ADD
macro, allowing usage of a variable name other than the struct element name.
Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which
the var name is the same as the struct element name.
Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name,
in order to avoid variable shadowing.

.. even when that "default y" is hidden syntactically as a

	default !EXPERT

it's wrong.

The only reason something should be 'default y' is if it used to be
built-in, and it was made configurable, and the 'default y' is just
retaining the status quo.

Altheratively, the hardware for the driver has become _so_ common that
it really makes sense for everybody to build it.  Finally, one possible
reason for 'default y' is because the option is not enabling any new
code at all, but is just enabling other options (the networking people
do this for vendor options, for example, so that you can disable whole
vendors at a time).

Clearly, none of these cases hold for the BigBen Interactive Kids'
gamepad, and HID_BIGBEN_FF should thus most definitely not default
to on for everybody.

Commit 9ee3e066 ("HID: i2c-hid: override HID descriptors for certain
devices") added a new dmi_system_id quirk table to override certain HID
report descriptors for some systems that lack them.

But the table wasn't properly terminated, causing the dmi matching to
walk off into la-la-land, and starting to treat random data as dmi
descriptor pointers, causing boot-time oopses if you were at all
unlucky.

Terminate the array.

We really should have some way to just statically check that arrays that
should be terminated by an empty entry actually are so.  But the HID
people really should have caught this themselves, rather than have me
deal with an oops during the merge window.  Tssk, tssk.
