Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog
has the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about
this code since it moved to staging last year, and if it needs
to come back, it can be reverted.
- lustre file system is removed. I've ranted at the lustre
developers about once a year for the past 5 years, with no
real forward progress at all to clean things up and get the
code into the "real" part of the kernel. Given that the
lustre developers continue to work on an external tree and try
to port those changes to the in-kernel tree every once in a
while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the
time working in their out-of-tree location and get things
cleaned up properly to get merged into the tree correctly at a
later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems.

The tag control information (TCI) part of the VLAN header contains several
fields, including PCP (priority code point) and PVID (port VLAN id).
Current implementation uses function ethsw_port_set_tci() to set the PVID
value and mistakenly overwrites the rest of the TCI fields with 0,
including PCP which by default has a value of 7.
Fix this by adding support to retrieve TCI set in hardware. Read existing

We use DPAA2_ETH_MAX_TX_QUEUES to dimension the array holding

supports have at most 16 cores, whereas NR_CPUS is Kconfigurable and
can be much higher.
Avoid allocating memory we'll never use, by setting
