These timers were a good idea but weren't used in current code,
and the idea was cifs specific. Future patch will add similar timers
for SMB2/SMB3, but no sense using memory for cifs timers that
aren't used in current code.

Remove counters from the per-tree connection /proc/fs/cifs/Stats
output that will always be zero (since they are not per-tcon ops)
ie SMB3 Negotiate, SessionSetup, Logoff, Echo, Cancel.
Also clarify "sent" to be "total" per-Pavel's suggestion
(since this "total" includes total for all operations that we try to
send whether or not succesffully sent). Sample output below:

For SMB2/SMB3 the number of requests sent was not displayed
in /proc/fs/cifs/Stats unless CONFIG_CIFS_STATS2 was
enabled (only number of failed requests displayed). As
with earlier dialects, we should be displaying these
counters if CONFIG_CIFS_STATS is enabled. They
are important for debugging.

We really, really want to be encouraging use of secure dialects,
and SMB3.1.1 offers useful security features, and will soon
be the recommended dialect for many use cases. Simplify the code
by removing the CONFIG_CIFS_SMB311 ifdef so users don't disable
it in the build, and create compatibility and/or security issues
with modern servers - many of which have been supporting this
dialect for multiple years.
Also clarify some of the Kconfig text for cifs.ko about
SMB3.1.1 and current supported features in the module.

In the fscache, we just need the timestamps as cookies to check for
changes, so we don't really care about the overflow, but it's better
to stop using the deprecated timespec so we don't have to go through
explicit conversion functions.
To avoid comparing uninitialized padding values that are copied
while assigning the timespec values, this rearranges the members of
cifs_fscache_inode_auxdata to avoid padding, and assigns them
individually.

====================
net: Support Wake-on-LAN using filters
This is technically a v2, but this patch series builds on your feedback
and defines the following:
- a new WAKE_* bit: WAKE_FILTER which can be enabled alongside other type
of Wake-on-LAN to support waking up on a programmed filter (match + action)
- a new RX_CLS_FLOW_WAKE flow action which can be specified by an user when
inserting a flow using ethtool::rxnfc, similar to the existing RX_CLS_FLOW_DISC
The bcm_sf2 and bcmsysport drivers are updated accordingly to work in concert to
allow matching packets at the switch level, identified by their filter location
to be used as a match by the SYSTEM PORT (CPU/management controller) during
Wake-on-LAN.
Let me know if this looks better than the previous incarnation of the patch
series.
Attached is also the ethtool patch that I would be submitting once the uapi
changes are committed.
Thank you!

The SYSTEMPORT MAC allows up to 8 filters to be programmed to wake-up
from LAN. Verify that we have up to 8 filters and program them to the
appropriate RXCHK entries to be matched (along with their masks).
We need to update the entry and exit to Wake-on-LAN mode to keep the
RXCHK engine running to match during suspend, but this is otherwise
fairly similar to Magic Packet detection.

Allow propagating ethtool::rxnfc programming to the CPU/management port
such that it is possible for such a CPU to perform e.g: Wake-on-LAN
using filters configured by the switch. We need a tiny bit of
cooperation between the switch drivers which is able to do the full flow
matching, whereas the CPU/management port might not. The CPU/management
driver needs to return -EOPNOTSUPP to indicate an non critical error,
any other error code otherwise.

Add the ability to specify through ethtool::rxnfc that a rule location is
special and will be used to participate in Wake-on-LAN, by e.g: having a
specific pattern be matched. When this is the case, fs->ring_cookie must
be set to the special value RX_CLS_FLOW_WAKE.
We also define an additional ethtool::wolinfo flag: WAKE_FILTER which
can be used to configure an Ethernet adapter to allow Wake-on-LAN using
previously programmed filters.

When the OF code was originally made common by Grant in commit
51975db0b733 ("of/flattree: merge early_init_dt_scan_memory() common
code") (Feb 2010), the common code inherited a hack to handle
PPC "longtrail" machines, which had a "memory@0" node with no
device_type.
That check was then made to only apply to PPC32 in b44aa25d20e2 ("of:
Handle memory@0 node on PPC32 only") (May 2014).
But according to Paul Mackerras the "longtrail" machines are long
dead, if they were ever seen in the wild at all. If someone does still
have one, we can handle this firmware wart in powerpc platform code.
So remove the hack once and for all.

Colin Ian King reports that commit 82ff27bc52 ("xfs: automatic dfops
buffer relogging") leaves around some dead error handling code in
xfs_dquot_disk_alloc(). This was discovered via Coverity scan.
Since the associated commit eliminates the act of joining a buffer
to a dfops, this intermediate error state is no longer possible and
the error handling code can be removed. Since the caller cancels the
transaction on error, which cancels the dfops, eliminate the
unnecessary xfs_defer_cancel() call and error handling labels.

The code in __write_64bit_c0_split() is used by MIPS32 kernels running
on MIPS64 CPUs to write a 64-bit value to a 64-bit coprocessor 0
register using a single 64-bit dmtc0 instruction. It does this by
combining the 2x 32-bit registers used to hold the 64-bit value into a
single register, which in the existing code involves three steps:
1) Zero extend register A which holds bits 31:0 of our data, since it
may have previously held a sign-extended value.
2) Shift register B which holds bits 63:32 of our data in bits 31:0
left by 32 bits, such that the bits forming our data are in the
position they'll be in the final 64-bit value & bits 31:0 of the
register are zero.
3) Or the two registers together to form the 64-bit value in one
64-bit register.
From MIPS r2 onwards we have a dins instruction which can effectively
perform all 3 of those steps using a single instruction.
Add a path for MIPS r2 & beyond which uses dins to take bits 31:0 from
register B & insert them into bits 63:32 of register A, giving us our
full 64-bit value in register A with one instruction.
Since we know that MIPS r2 & above support the sel field for the dmtc0
instruction, we don't bother special casing sel==0. Omiting the sel
field would assemble to exactly the same instruction as when we
explicitly specify that it equals zero.

Commit c22c80431055 ("MIPS: Fix input modify in

clobbering an input.
The way in which we use both an output & an input parameter with the

also problematic for clang, which complains if the input & output values
have different widths. For example:

We can both fix this build failure & simplify the code somewhat by
assigning the __tmp variable with the input value in C prior to our

a constraint beginning with +) to provide this value to our assembly.

The priority flow control statistics are laid out in the stats structure
using arrays. This made it unwieldy to use as part of an i40e_stats
array.
Add a new structure type, i40e_pfc_stats, and a helper function
i40e_get_pfc_stats which can return the stats for a given priority
value as an i40e_pfc_stats structure.
Use this to create an i40e_stats array, which we'll use to format and
copy the strings and stats into the supplied buffers.
This reduces even more boiler plate code in i40e_get_ethtool_stats and
i40e_get_stat_strings.
An alternative would be to modify the structure definition for the pfc
stats, but this is more invasive to the rest of the code base.
Note that a macro was used to setup the copy of stats from the
pf->stats, as this reduces the chance of typos in the code names. It
will produce a checkpatch.pl warning due to re-use of a macro argument.
In this case, it should be safe, as the macro will fail to compile in
cases where the argument is not a simple structure member name, and thus
arguments with side effects should not be an issue.

The VEB TC stats are currently implemented with separate parsing,
instead of using the i40e_stats array and associated helper functions.
This is likely because the stats rely on embedding the TC number into
the stat name.
Update i40e_add_stat_strings to take variadic arguments, and use these
to vsnprintf the i40e_stats string as a string containing format
specifiers.
Create a stats array for the VEB TC related stats,
i40e_gstrings_veb_tc_stats, and use this along with the helper functions
to remove the specialized boiler plate code.
Always call i40e_add_ethtool_stats for both this array and the general
VEB stats array. This ensures that we zero out any memory in case it was

This ultimately results in less boiler plate code for the
i40e_get_stat_strings and i40e_get_ethtool_stats.

This patch configures FEC setting in i40e_force_link_state().
For some reason setting this field was overlooked thus causing
25G link to be configured incorrectly.

Similar to the helper function to copy the ethtool stats strings, add
and use a helper function for copying the ethtool stats into the
supplied buffer.
Just like before, we use a macro to avoid having to pass ARRAY_SIZE
manually, so as to reduce chance of bugs.
Some of the stats, especially queue stats, are a bit trickier, and will
be handled in future patches.

Many of the ethtool statistics use the same basic logic for copying
strings into the supplied buffer. A set of stats are stored in a const
array of i40e_stats structures, and we apply these all together.
Simplify the stats code by introducing a helper function which can take
a stats array and copy the strings into the buffer, updating the buffer
pointer as we go.
We use a macro to implement i40e_add_stat_strings so that ARRAY_SIZE can
be used on the array passed in. This ensures that we always use the
matching size in __i40e_add_stat_strings.
More complex stats currently do not use i40e_stats arrays, usually due
to custom formatted strings, or because the stats are not laid out in
the expected way. These stats will be updated to use the helper function
in separate future patches.

Function call to i40e_prep_for_reset() is duplicated in
i40e_shutdown routine and gets called before
i40e_enable_mc_magic_wake() which blocks it from being executed
correctly on system reboot or shutdown because adminq is already
disabled by first i40e_prep_for_reset() call.
Two register write calls are also duplicated.

The timeout policy is currently embedded into the nfnetlink_cttimeout
object, move the policy into an independent object. This allows us to
reuse part of the existing conntrack timeout extension from nf_tables
without adding dependencies with the nfnetlink_cttimeout object layout.

For some reason order of startup/hw_params/prepare are reversed
in dynamic compress usecase when compared to dpcm usecase. This is
a issue with platforms like QCOM where it expects the BE to be
initialized before FE.
Interestingly the compress trigger callback order is inline with dpcm.
Am not 100% sure why the compress audio case has been reversed.
This patch is making the order inline with dpcm.
If the reverse ordering is just co-incendental then this change
makes sense and will avoid inventing some new mechanism to cope
with ordering.
