Introduce a mv88e6xxx_ops structure to describe supported chip-wide
functions and assign the correct variant to the chip models.
For the moment, add only PHY access routines. This allows to get rid of
the PHY ops structures and the usage of PHY flags.

The mv88e6xxx_ops is used to describe how to access the chip registers.
It can be through SMI (via an MDIO bus), or via another interface such
as crafted remote management frames.
The correct BUS operations structure is chosen at runtime, depending on
the chip address and connectivity.
We will need the mv88e6xxx_ops name for future chip-wide operation
structure, thus rename mv88e6xxx_ops to more explicit mv88e6xxx_bus_ops.

The STU (if the switch has one) is abstracted and accessed through the
VTU operations and data registers.
Thus rename the mv88e6xxx_vtu_stu_entry struct to mv88e6xxx_vtu_entry.

The Global (1) internal SMI device is an extended set of registers
containing ATU, PPU, VTU, STU, etc.
It is present on every switches, usually at SMI address 0x1B. But old
models such as 88E6060 access it at address 0xF, thus using REG_GLOBAL
is erroneous.
Add a global1_addr info member used by mv88e6xxx_g1_{read,write} and
mv88e6xxx_g1_wait helpers in a new global1.c file.
This patch finally removes _mv88e6xxx_reg_{read,write}, in favor on the
appropriate helpers. No functional changes here.

We can easily support parallel direct IO reads. We only have to make
sure we cannot expose uninitialized data by reading allocated block to
which data was not written yet, or which was already truncated. That is
easily achieved by holding inode_lock in shared mode - that excludes all
writes, truncates, hole punches. We also have to guard against page
writeback allocating blocks for delay-allocated pages - that race is
handled by the fact that we writeback all the pages in the affected
range and the lock protects us from new pages being created there.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm fixes from Dan Williams:
- Four fixes for "flush hint" support.
Flush hints are addresses advertised by the ACPI 6+ NFIT (NVDIMM
Firmware Interface Table) that when written and fenced guarantee that
writes pending in platform write buffers (outside the cpu) have been
flushed to media. They might also be used by hypervisors as a
trigger condition to flush guest-persistent memory ranges to storage.
Fix a potential data corruption issue, a broken definition of the
hint array, a wrong allocation size for the unit test implementation
of the flush hint table, and missing NULL check in an error path.
The unit test, while it did not prevent these bugs from being
merged, at least triggered occasional crashes in advance of
production usages.
- Fix handling of ACPI DSM error status results. The DSM mechanism
allows communication with platform and memory device firmware. We
correctly parse known errors, but were silently ignoring others.
Fix it to consistently fail any command with a non-zero status return
that we otherwise do not interpret / handle.
* 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:

Note the serial number of the packet being ACK'd in the congestion
management trace rather than the serial number of the ACK packet. Whilst
the serial number of the ACK packet is useful for matching ACK packet in
the output of wireshark, the serial number that the ACK is in response to
is of more use in working out how different trace lines relate.

Reduce the rxrpc_local::services list to just a pointer as we don't permit
multiple service endpoints to bind to a single transport endpoints (this is
excluded by rxrpc_lookup_local()).
The reason we don't allow this is that if you send a request to an AFS
filesystem service, it will try to talk back to your cache manager on the
port you sent from (this is how file change notifications are handled). To
prevent someone from stealing your CM callbacks, we don't let AF_RXRPC
sockets share a UDP socket if at least one of them has a service bound.

In rxrpc_activate_channels(), the connection cache state is checked outside
of the lock, which means it can change whilst we're waking calls up,
thereby changing whether or not we're allowed to wake calls up.
Fix this by moving the check inside the locked region. The check to see if
all the channels are currently busy can stay outside of the locked region.
Whilst we're at it:
(1) Split the locked section out into its own function so that we can call
it from other places in a later patch.
(2) Determine the mask of channels dependent on the state as we're going
to add another state in a later patch that will restrict the number of
simultaneous calls to 1 on a connection.

In rxrpc_send_data_packet() make the loss-injection path return through the
same code as the transmission path so that the RTT determination is
initiated and any future timer shuffling will be done, despite the packet
having been binned.
Whilst we're at it:
(1) Add to the tx_data tracepoint an indication of whether or not we're
retransmitting a data packet.
(2) When we're deciding whether or not to request an ACK, rather than
checking if we're in fast-retransmit mode check instead if we're
retransmitting.
(3) Don't invoke the lose_skb tracepoint when losing a Tx packet as we're
not altering the sk_buff refcount nor are we just seeing it after
getting it off the Tx list.
(4) The rxrpc_skb_tx_lost note is then no longer used so remove it.
(5) rxrpc_lose_skb() no longer needs to deal with rxrpc_skb_tx_lost.

Exclusive connections are currently reusable (which they shouldn't be)
because rxrpc_alloc_client_connection() checks the exclusive flag in the
rxrpc_connection struct before it's initialised from the function
parameters. This means that the DONT_REUSE flag doesn't get set.
Fix this by checking the function parameters for the exclusive flag.

MMU initialization option is currently ignored on MMUv2 cores, but it is
used in Kconfig to select kernel load and start addresses. This choice
is not available for MMUv2 cores as they have hardwired TLB entries.
Disable MMU initialization option for known MMUv2 cores so that they get
correct kernel load/start address by default.
This fixes the default allmodconfig build.

The recent series of changes to the caching in the SSI driver have
caused a number of problems to appear in some test systems. These are
still not fully understood but we're coming up to the merge window so
for now let's revert commit 7de2763d9b3 (ASoC: fsl_ssi: Remove
.num_reg_defaults_raw from regmap_config) as backing that out seems to
resolve the problem on affected systems.
