Nobody is maintaining SMTC anymore and there also seems to be no userbase.
Which is a pity - the SMTC technology primarily developed by Kevin D.
Kissell <kevink@paralogos.com> is an ingenious demonstration for the MT
ASE's power and elegance.
Based on Markos Chandras <Markos.Chandras@imgtec.com> patch
https://patchwork.linux-mips.org/patch/6719/ which while very similar did
no longer apply cleanly when I tried to merge it plus some additional
post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to
merge once upon a time.

Commit 1d9fe6b97 ("clk: divider: Fix best div calculation for power-of-two and
table dividers") introduces a regression in its _table_round_up function.
When the divider passed to this function is greater than the max divider
available in the table, this function returns table's max divider.
Problem is that it causes an infinite loop in clk_divider_bestdiv() because
_next_div() will never return a value greater than maxdiv.
Instead of returning table's max divider, this patch returns INT_MAX.

The patch 3e374919b314f20e2a04f641ebc1093d758f66a4 is supposed to fix the
problem where kmem_cache_create incorrectly reports duplicate cache name
and fails. The problem is described in the header of that patch.
However, the patch doesn't really fix the problem because of these
reasons:
* the logic to test for debugging is reversed. It was intended to perform
the check only if slub debugging is enabled (which implies that caches
with the same parameters are not merged). Therefore, there should be
#if !defined(CONFIG_SLUB) || defined(CONFIG_SLUB_DEBUG_ON)
The current code has the condition reversed and performs the test if
debugging is disabled.
* slub debugging may be enabled or disabled based on kernel command line,
CONFIG_SLUB_DEBUG_ON is just the default settings. Therefore the test
based on definition of CONFIG_SLUB_DEBUG_ON is unreliable.
This patch fixes the problem by removing the test
"!defined(CONFIG_SLUB_DEBUG_ON)". Therefore, duplicate names are never
checked if the SLUB allocator is used.
Note to stable kernel maintainers: when backporint this patch, please
backport also the patch 3e374919b314f20e2a04f641ebc1093d758f66a4.

This patch adds three more test cases:
1) long jumps with holes of unreachable code
2) ret x
3) ldx + ret x
All three tests are for classical BPF and to make sure that
any changes will not break some exotic behaviour that exists
probably since decades. The last two tests are expected to
fail by the BPF checker already, as in classic BPF only K
or A are allowed to be returned. Thus, there are now 52 test
cases for BPF.

The sk_unattached_filter_create() API is used by BPF filters that
are not directly attached or related to sockets, and are used in
team, ptp, xt_bpf, cls_bpf, etc. As such all users do their own
internal managment of obtaining filter blocks and thus already
have them in kernel memory and set up before calling into
sk_unattached_filter_create(). As a result, due to __user annotation
in sock_fprog, sparse triggers false positives (incorrect type in
assignment [different address space]) when filters are set up before
passing them to sk_unattached_filter_create(). Therefore, let
sk_unattached_filter_create() API use sock_fprog_kern to overcome
this issue.

Lets get rid of this macro. After commit 5bcfedf06f7f ("net: filter:
simplify label names from jump-table"), labels have become more
readable due to omission of BPF_ prefix but at the same time more
generic, so that things like `git grep -n` would not find them. As
a middle path, lets get rid of the DL macro as it's not strictly
needed and would otherwise just hide the full name.

net: Checksum offload changes - Part III
I am working on overhauling RX checksum offload. Goals of this effort
are:
- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code
What is in this third patch set:
- Remove sk_no_check from sunrpc (doesn't seem to have any effect)
- Eliminate no_check from protosw. All protocols are using default of
zero for this
- Split sk_no_check into sk_no_check_tx and sk_no_check_rx
- Make enabling of UDP6 more restrictive and explicit
- Support zero UDP6 checksums in l2tp
V2: Took out vxlan changes to set zero csums in IPv6, this will
be in a later patch set.
V3: Fixed bug in restricting UDP6 checksums.
Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)

Added new L2TP configuration options to allow TX and RX of
zero checksums in IPv6. Default is not to use them.

RFC 6935 permits zero checksums to be used in IPv6 however this is
recommended only for certain tunnel protocols, it does not make
checksums completely optional like they are in IPv4.
This patch restricts the use of IPv6 zero checksums that was previously
intoduced. no_check6_tx and no_check6_rx have been added to control
the use of checksums in UDP6 RX and TX path. The normal
sk_no_check_{rx,tx} settings are not used (this avoids ambiguity when
dealing with a dual stack socket).
A helper function has been added (udp_set_no_check6) which can be
called by tunnel impelmentations to all zero checksums (send on the
socket, and accept them as valid).

Define separate fields in the sock structure for configuring disabling
checksums in both TX and RX-- sk_no_check_tx and sk_no_check_rx.
The SO_NO_CHECK socket option only affects sk_no_check_tx. Also,
removed UDP_CSUM_* defines since they are no longer necessary.

It doesn't seem like an protocols are setting anything other
than the default, and allowing to arbitrarily disable checksums
for a whole protocol seems dangerous. This can be done on a per
socket basis.

Setting sk_no_check to UDP_CSUM_NORCV seems to have no effect.

====================
Intel Wired LAN Driver Updates
This series contains updates to igb, igbvf, ixgbe, i40e and i40evf.
Jacob provides eight patches to cleanup the ixgbe driver to resolve various
checkpatch.pl warnings/errors as well as minor coding style issues.
Stephen Hemminger and I provide simple cleanups of void functions which
had useless return statements at the end of the function which are not
needed.
v2: Dropped Emil's patch "ixgbe: fix the detection of SFP+ capable interfaces"
while I wait for his updated patch to be validated.

Currently blk-mq uses the queue timeout for all requests. But
for some commands, drivers may want to set a specific timeout
for special requests. Allow this to be passed in through
request->timeout, and use it if set.
