With this patch, the SOF kernel patches are officially aligned with

This tablet has an incorrect acpi identifier just like
Thinkpad10 tablet, which is why it is trying to load the RT5640 driver
instead of the RT5762 driver. The RT5640 driver, on the other hand, checks
the hardware ID, so no driver are loaded during boot. This fix resolves to
load the RT5672 driver on this tablet during boot. It also provides the
correct IO configuration, like the jack detect mode 3, for 1.8V pullup. I
would like to thank Pierre-Louis Bossart for helping with this patch.

As explained in
0cc3cd2165 ("cpu/hotplug: Boot HT siblings at least once")
we always, no matter what, have to bring up x86 HT siblings during boot at
least once in order to avoid first MCE bringing the system to its knees.
That means that whenever 'nosmt' is supplied on the kernel command-line,
all the HT siblings are as a result sitting in mwait or cpudile after
going through the online-offline cycle at least once.
This causes a serious issue though when a kernel, which saw 'nosmt' on its
commandline, is going to perform resume from hibernation: if the resume
from the hibernated image is successful, cr3 is flipped in order to point
to the address space of the kernel that is being resumed, which in turn
means that all the HT siblings are all of a sudden mwaiting on address
which is no longer valid.
That results in triple fault shortly after cr3 is switched, and machine
reboots.
Fix this by always waking up all the SMT siblings before initiating the
'restore from hibernation' process; this guarantees that all the HT
siblings will be properly carried over to the resumed kernel waiting in
resume_play_dead(), and acted upon accordingly afterwards, based on the
target kernel configuration.
Symmetricaly, the resumed kernel has to push the SMT siblings to mwait
again in case it has SMT disabled; this means it has to online all
the siblings when resuming (so that they come out of hlt) and offline
them again to let them reach mwait.

In a rare case, flush_tlb_kernel_range() could be called with a start
higher than the end.
In vm_remove_mappings(), in case page_address() returns 0 for all pages
(for example they were all in highmem), _vm_unmap_aliases() will be
called with start = ULONG_MAX, end = 0 and flush = 1.
If at the same time, the vmalloc purge operation is triggered by something
else while the current operation is between remove_vm_area() and
_vm_unmap_aliases(), then the vm mapping just removed will be already
purged. In this case the call of vm_unmap_aliases() may not find any other
mappings to flush and so end up flushing start = ULONG_MAX, end = 0. So
only set flush = true if we find something in the direct mapping that we
need to flush, and this way this can't happen.

The calculation of the direct map address range to flush was wrong.
This could cause the RO direct map alias to not get flushed. Today
this shouldn't be a problem because this flush is only needed on x86
right now and the spurious fault handler will fix cached RO->RW
translations. In the future though, it could cause the permissions
to remain RO in the TLB for the direct map alias, and then the page
would return from the page allocator to some other component as RO
and cause a crash.
So fix fix the address range calculation so the flush will include the
direct map range.

net: add rcu annotations for ifa_list
v3: fix typo in patch1 commit message
All other patches are unchanged.
v2: remove ifa_list iteration in afs instead of conversion
Eric Dumazet reported following problem:
It looks that unless RTNL is held, accessing ifa_list needs proper RCU
protection. indev->ifa_list can be changed under us by another cpu
(which owns RTNL) [..]
A proper rcu_dereference() with an happy sparse support would require
adding __rcu attribute.
This patch series does that: add __rcu to the ifa_list pointers.
That makes sparse complain, so the series also adds the required
rcu_assign_pointer/dereference helpers where needed.
All patches except the last one are preparation work.
Two new macros are introduced for in_ifaddr walks.
Last patch adds the __rcu annotations and the assign_pointer/dereference
helper calls.
This patch is a bit large, but I found no better way -- other
approaches (annotate-first or add helpers-first) all result in
mid-series sparse warnings.
This series is submitted vs. net-next rather than net for several
reasons:
1. Its (mostly) compile-tested only
2. 3rd patch changes behaviour wrt. secondary addresses
(see changelog)
3. The problem exists for a very long time (2004), so it doesn't
seem to be urgent to fix this -- rcu use to free ifa_list
predates the git era.

The list is actually useless as it's the client's view of the world,
not the servers, so if there's any NAT in the way its contents are
invalid. Further, it doesn't support IPv6 addresses.
On that basis, feel free to make it an empty list and remove all the
interface enumeration.
V1 of this patch reworked the function to use a new helper for the
ifa_list iteration to avoid sparse warnings once the proper __rcu
annotations get added in struct in_device later.
But, in light of the above, just remove afs_get_ipv4_interfaces.

It turns out that the suggestion from Karsten Keil wa to remove I4L

happened now (with a very small number of exceptions), so I guess it's
time to try again.
We currently have three ISDN stacks in the kernel: the original
isdn4linux (with the hisax driver), the newer CAPI (with four drivers),
and finally the mISDN stack (supporting roughly the same hardware as
hisax).
As far as I can tell, anyone using ISDN with mainline kernel drivers in
the past few years uses mISDN, and this is typically used for voice-only
PBX installations that don't require a public network.
The older stacks support additional features for data networks, but those
typically make no sense any more if there is no network to connect to.
My proposal for this time is to kill off isdn4linux entirely, as it seems
to have been unusable for quite a while. This code has been abandoned
for many years and it does cause problems for treewide maintenance as
it tends to do everything that we try to stop doing.
Birger Harzenetter mentioned that is is still using i4l in order to
make use of the 'divert' feature that is not part of mISDN, but has
otherwise moved on to mISDN for normal operation, like apparently
everyone else.
CAPI in turn is not quite as obsolete, but two of the drivers (avm
and hysdn) don't seem to be used at all, while another one (gigaset)
will stop being maintained as Paul Bolle is no longer able to
test it after the network gets shut down in September.
All three are now moved into drivers/staging to let others speak
up in case there are remaining users.
This leaves Bluetooth CMTP as the only remaining user of CAPI, but

====================
Add hw offload of TC flower on MSCC Ocelot
This patch series enables hardware offload for flower filter used in
traffic controller on MSCC Ocelot board.
v2->v3 changes:
- remove the check for shared blocks
v1->v2 changes:
- when declaring variables use reverse christmas tree
====================

Hardware offload of port filtering are now supported via tc command using
flower filter. ACL rules are used to enable the hardware offload.
The following keys are supported:
vlan_id
vlan_prio
dst_mac/src_mac for non IP frames
dst_ip/src_ip
dst_port/src_port
The following actions are supported:
trap
drop
These filters are supported only on the ingress schedulare.
Add:
tc qdisc add dev eth3 ingress
tc filter ad dev eth3 parent ffff: ip_proto ip flower \
ip_proto tcp dst_port 80 action drop

Add ACL support using the TCAM. Using ACL it is possible to create rules
in hardware to filter/redirect frames.

Here are just two small patches, that fix up some found SPDX identifier
issues.
The first patch fixes an error in a previous SPDX fixup patch, that
causes build errors when doing 'make clean' on the tree (the fact that
almost no one noticed it reflects the fact that kernel developers don't
like doing that option very often...)
The second patch fixes up a number of places in the tree where people
mistyped the string "SPDX-License-Identifier". Given that people can
not even type their own name all the time without mistakes, this was
bound to happen, and odds are, we will have to add some type of check
for this to checkpatch.pl to catch this happening in the future.
Both of these have passed testing by 0-day.

A minor fix to our IMC PMU code to print a less confusing error message when the
driver can't initialise properly.
A fix for a bug where a user requesting an unsupported branch sampling filter
can corrupt PMU state, preventing the PMU from counting properly.
And finally a fix for a bug in our support for kexec_file_load(), which
prevented loading a kernel and initramfs. Most versions of kexec don't yet use
kexec_file_load().
