Previously a temporary tasklet structure was initialized on the stack
using DECLARE_TASKLET_OLD() and then copied over and modified. Nothing
else in the kernel seems to use this pattern, so let's just call
tasklet_init() like everyone else.

Till now the code assumed that need to copy reduced size of the
ste because the rest is the mask part which shouldn't be changed.
This is not true for all types of HW (like STEv1).
Take all 64B from the new STE and write them in the replaced STE place.
This change will make it easier to handle all STE HW types because we have
all the data that is about to be written into HW.

STEv0 format and STEv1 HW format are different, each has a
different order:
STEv0: CTRL 32B, TAG 16B, BITMASK 16B
STEv1: CTRL 32B, BITMASK 16B, TAG 16B
To make this transparent to upper layers we introduce a
new ste_ctx function to format the STE prior to writing it.

In these cases we need to update only the ctrl area of the STE.
So it is better to write only the control 32B and avoid copying

net/sched: cls_flower: Add support for matching on ct_state reply flag
This patchset adds software match support and offload of flower
match ct_state reply flag (+/-rpl).
The first patch adds the definition for the flag and match to flower.
Second patch gives the direction of the connection to the offloading
drivers via ct_metadata flow offload action.
The last patch does offload of this new ct_state by using the supplied
connection's direction.

Pointers to receive-buffer packets sent by Hyper-V are used within the
guest VM. Hyper-V can send packets with erroneous values or modify
packet fields after they are processed by the guest. To defend against
these scenarios, copy (sections of) the incoming packet after validating
their length and offset fields in netvsc_filter_receive(). In this way,
the packet can no longer be modified by the host.

The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.
This causes the driver to be enable under make ARCH=um allyesconfig,
even though it won't build.
By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

Pull ACPI fixes from Rafael Wysocki:
"These fix the handling of notifications in the ACPI thermal driver and
address a device enumeration issue leading to the presence of multiple
'MODALIAS=' entries in one uevent file in sysfs in some cases.
Specifics:
- Modify the ACPI thermal driver to avoid evaluating _TMP directly in
its Notify () handler callback and running too many thermal checks
for one thermal zone at the same time so as to address a work item
accumulation issue observed on some systems that fail to shut down
as a result of it (Rafael Wysocki)
- Modify the ACPI uevent file creation code to avoid putting multiple
'MODALIAS=' entries in one uevent file in sysfs which breaks
systemd-udevd (Kai-Heng Feng)"

It turns out that the vfs_iocb_iter_{read,write}() functions are
entirely broken, and don't actually use the passed-in file pointer for
IO - only for the preparatory work (permission checking and for the
write_iter function lookup).
That worked fine for overlayfs, which always builds the new iocb with
the same file pointer that it passes in, but in the general case it ends
up doing nonsensical things (and could cause an iterator call that
doesn't even match the passed-in file pointer).
This subtly broke the tty conversion to write_iter in commit
9bb48c82ac ("tty: implement write_iter"), because the console
redirection didn't actually end up redirecting anything, since the
passed-in file pointer was basically ignored, and the actual write was
done with the original non-redirected console tty after all.
The main visible effect of this is that the console messages were no
longer logged to /var/log/boot.log during graphical boot.
Fix the issue by simply not using the vfs write "helper" function at
all, and just redirecting the write entirely internally to the tty
layer. Do the target writability permission checks when actually
registering the target tty with TIOCCONS instead of at write time.

To avoid potential compilation problems, replaced the badly written
MB_TO_SECTS() macro (missing parenthesis around the argument use) with
the inline function mb_to_sects(). And while at it, simplify the
calculation of the total number of zones of the device using the
round_up() macro.

This patch unifies the error messages:
- have a "." and the end of each message
- write controller with a small "c", if not the first word of an error
message.

The published errata specify the maximum allowed SPI frequency to be
max 85% of (FSYSCLK/2). So there's no need to track known bad clock
settings in the driver. As the setup of known good values is a bit
tricky, keep them.
