With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

The tulip driver causes annoying build-time warnings for allmodconfig
builds for all recent architectures:
dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined
dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined!
This is the last remaining warning for arm64, and I'd like to get rid of
it. We don't really know the cache line size, architecturally it would
be at least 16 bytes, but all implementations I found have 64 or 128
bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to
be the safe but slow default, and nobody who cares about performance these
days would use a tulip chip anyway, so we can just use that.
To save the next person the job of trying to find out what this is for
and picking a default for their architecture just to kill off the warning,
I'm now removing the preprocessor #warning and turning it into a pr_warn
or dev_warn that prints the equivalent information when the driver gets
loaded.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.

independent of it (no braces before the "if" at line 1087).
This patch fixes the indentation to reflect the actual meaning of the code,
though is it actually meant to be part of the "else" clause? (I'm a

the assignment, to placate checkpatch.pl.

net/core/sysctl_net_core.c
net/ipv4/inet_diag.c
The be_main.c conflict resolution was really tricky. The conflict
hunks generated by GIT were very unhelpful, to say the least. It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().
So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged. And this worked beautifully.
The inet_diag.c and sysctl_net_core.c conflicts were simple

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

The ath9k Kconfig conflict was a change of a Kconfig option name right
next to the deletion of another option.
The xen-netback conflict was overlapping changes involving the
handling of the notify list in xen_netbk_rx_action().
Batman conflict resolution provided by Antonio Quartulli, basically
keep everything in both conflict hunks.
The nl80211 conflict is a little more involved. In 'net' we added a
dynamic memory allocation to nl80211_dump_wiphy() to fix a race that
Linus reported. Meanwhile in 'net-next' the handlers were converted
to use pre and post doit handlers which use a flag to determine
whether to hold the RTNL mutex around the operation.
However, the dump handlers to not use this logic. Instead they have
to explicitly do the locking. There were apparent bugs in the
conversion of nl80211_dump_wiphy() in that we were not dropping the
RTNL mutex in all the return paths, and it seems we very much should
be doing so. So I fixed that whilst handling the overlapping changes.
To simplify the initial returns, I take the RTNL mutex after we try
to allocate 'tb'.
