The main change here is a fix for a number of unsafe interactions
between kdb and the console system. The fixes are specific to kdb (pure
kgdb debugging does not use the console system at all). On systems with
an NMI then kdb, if it is enabled, must get messages to the user despite
potentially running from some "difficult" calling contexts. These fixes
avoid using the console system where we have been provided an
alternative (safer) way to interact with the user and, if using the
console system in unavoidable, use oops_in_progress for deadlock
avoidance. These fixes also ensure kdb honours the console enable flag.
Also included is a fix that wraps kgdb trap handling in an RCU read lock
to avoids triggering diagnostic warnings. This is a wide lock scope but
this is OK because kgdb is a stop-the-world debugger. When we stop the
world we put all the CPUs into holding pens and this inhibits RCU update
anyway.

Inlining these helpers again also avoids the function call overhead when

40GbE Intel Wired LAN Driver Updates 2020-06-25
This series contains updates to i40e driver and removes the individual
driver versions from all of the Intel wired LAN drivers.
Shiraz moves the client header so that it can easily be shared between
the i40e LAN driver and i40iw RDMA driver.
Jesse cleans up the unused defines, since they are just dead weight.
Alek reduces the unreasonably long wait time for a PF reset after reboot
by using jiffies to limit the maximum wait time for the PF reset to
succeed. Added additional logging to let the user know when the driver
transitions into recovery mode. Adds new device support for our 5 Gbps
NICs.
Todd adds a check to see if MFS is set after warm reboot and notifies
the user when MFS is set to anything lower than the default value.
Arkadiusz fixes a possible race condition, where were holding a
spin-lock while in atomic context.
v2: removed code comments that were no longer applicable in patch 2 of
the series. Also removed 'inline' from patch 4 and patch 8 of the
series. Also re-arranged code to be able to remove the forward
function declarations. Dropped patch 9 of the series, while the
author works on cleaning up the commit message.

In kgdb context, calling console handlers aren't safe due to locks used
in those handlers which could in turn lead to a deadlock. Although, using
oops_in_progress increases the chance to bypass locks in most console
handlers but it might not be sufficient enough in case a console uses
more locks (VT/TTY is good example).
Currently when a driver provides both polling I/O and a console then kdb
will output using the console. We can increase robustness by using the
currently active polling I/O driver (which should be lockless) instead
of the corresponding console. For several common cases (e.g. an
embedded system with a single serial port that is used both for console
output and debugger I/O) this will result in no console handler being
used.
In order to achieve this we need to reverse the order of preference to
use dbg_io_ops (uses polling I/O mode) over console APIs. So we just
store "struct console" that represents debugger I/O in dbg_io_ops and
while emitting kdb messages, skip console that matches dbg_io_ops
console in order to avoid duplicate messages. After this change,
"is_console" param becomes redundant and hence removed.

Patch "mm: workingset: let cache workingset challenge anon fix" is the

And, the other two are minor things which are found when I try to rebase
my patchset.
This patch (of 3):
After ("mm: workingset: let cache workingset challenge anon fix"), we
compare refault distances to active_file + anon. But age of the
non-resident information is only driven by the file LRU. As a result,
we may overestimate the recency of any incoming refaults and activate
them too eagerly, causing unnecessary LRU churn in certain situations.
Make anon aging drive nonresident age as well to address that.

We use a second pointer to always have a reference on the currently

nand_ecc_req structure into nand_ecc_props. This structure will be the
base of a wider 'nand_ecc' structure.
In nand_device, these properties are still named "eccreq" even if
"eccprops" might be more descriptive. This is just a transition step,
this field is being replaced very soon by a much wider structure. The
impact of renaming this field would be huge compared to its interest.

We haven't used string.h since the memcpy calls were removed so
this patch removes its inclusion. The file uaccess.h isn't needed
at all. However, removing it reveals that we do need to add an
inclusion for refcount.h.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net, they are:
1) Unaligned atomic access in ipset, from Russell King.
2) Missing module description, from Rob Gill.
3) Patches to fix a module unload causing NULL pointer dereference in
xtables, from David Wilder. For the record, I posting here his cover
letter explaining the problem:
A crash happened on ppc64le when running ltp network tests triggered by
"rmmod iptable_mangle".
See previous discussion in this thread:
https://lists.openwall.net/netdev/2020/06/03/161 .
In the crash I found in iptable_mangle_hook() that
state->net->ipv4.iptable_mangle=NULL causing a NULL pointer dereference.
net->ipv4.iptable_mangle is set to NULL in +iptable_mangle_net_exit() and
called when ip_mangle modules is unloaded. A rmmod task was found running
in the crash dump. A 2nd crash showed the same problem when running
"rmmod iptable_filter" (net->ipv4.iptable_filter=NULL).
To fix this I added .pre_exit hook in all iptable_foo.c. The pre_exit will
un-register the underlying hook and exit would do the table freeing. The
netns core does an unconditional +synchronize_rcu after the pre_exit hooks
insuring no packets are in flight that have picked up the pointer before
completing the un-register.
These patches include changes for both iptables and ip6tables.
We tested this fix with ltp running iptables01.sh and iptables01.sh -6 a
loop for 72 hours.
4) Add a selftest for conntrack helper assignment, from Florian Westphal.
