0day reported one -22.7% regression for will-it-scale page_fault2
case [1] on a 4 sockets 144 CPU platform, and bisected to it to be
caused by Waiman's optimization (commit bd0b230fe1) of saving one
'struct page_counter' space for 'struct mem_cgroup'.
Initially we thought it was due to the cache alignment change introduced
by the patch, but further debug shows that it is due to some hot data
members ('vmstats_local', 'vmstats_percpu', 'vmstats') sit in 2 adjacent
cacheline (2N and 2N+1 cacheline), and when adjacent cache line prefetch
is enabled, it triggers an "extended level" of cache false sharing for
2 adjacent cache lines.
So exchange the 2 member blocks, while keeping mostly the original
cache alignment, which can restore and even enhance the performance,
and save 64 bytes of space for 'struct mem_cgroup' (from 2880 to 2816,
with 0day's default RHEL-8.3 kernel config)

When one task is in io_uring_cancel_files() and another is doing
io_prep_async_work() a race may happen. That's because after accounting
a request inflight in first call to io_grab_identity() it still may fail
and go to io_identity_cow(), which migh briefly keep dangling
work.identity and not only.
Grab files last, so io_prep_async_work() won't fail if it did get into
->inflight_list.
note: the bug shouldn't exist after making io_uring_cancel_files() not
poking into other tasks' requests.

Yoga 11e 4th gen
The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has
one battery which is named BAT1 instead of the expected BAT0, add a
quirk for this. This fixes not being able to set the charging tresholds
on this model; and this alsoe fixes the following errors in dmesg:
ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error
thinkpad_acpi: Error probing battery 2
battery: extension failed to load: ThinkPad Battery Extension
battery: extension unregistered: ThinkPad Battery Extension
Note that the added quirk is for the "R0K" BIOS versions which are
used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there
is a separate "R0L" BIOS for the i3/i5 based versions. This may also
need the same quirk, but if that really is necessary is unknown.

The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.
The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:
1. Not show the onscreen keyboard when a text-input field is focussed
with the touchscreen.
2. Disable accelerometer based auto display-rotation.
This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.
Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.
Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

When offlining a CPU, powerpc/64s does not flush TLBs, rather it just
leaves the CPU set in mm_cpumasks, so it continues to receive TLBIEs
to manage its TLBs.
However the exit_flush_lazy_tlbs() function expects that after
returning, all CPUs (except self) have flushed TLBs for that mm, in
which case TLBIEL can be used for this flush. This breaks for offline
CPUs because they don't get the IPI to flush their TLB. This can lead
to stale translations.
Fix this by clearing the CPU from mm_cpumasks, then flushing all TLBs
before going offline.
These offlined CPU bits stuck in the cpumask also prevents the cpumask
from being trimmed back to local mode, which means continual broadcast
IPIs or TLBIEs are needed for TLB flushing. This patch prevents that
situation too.
A cast of many were involved in working this out, but in particular
Milton, Aneesh, Paul made key discoveries.

powerpc/64s keeps a counter in the mm which counts bits set in
mm_cpumask as well as other things. This means it can't use generic code
to clear bits out of the mask and doesn't adjust the arch specific
counter.

clear_tasks_mm_cpumask().

The firmware on the original USB2CAN by Geschwister Schneider Technologie
Entwicklungs- und Vertriebs UG exchanges all data between the host and the
device in host byte order. This is done with the struct
gs_host_config::byte_order member, which is sent first to indicate the desired
byte order.
The widely used open source firmware candleLight doesn't support this feature
and exchanges the data in little endian byte order. This breaks if a device
with candleLight firmware is used on big endianess systems.
To fix this problem, all u32 (but not the struct gs_host_frame::echo_id, which
is a transparent cookie) are converted to __le32.

As defined at ETSI TS 101 162, original network IDs up to 0xfebf
are reserved for registration at dvb.org.
Let's use, instead, an original network ID at the range

As the same value is also used for the network ID,
the range 0xff01-0xffff also fits better, as values
lower than that depend if the network is used for
satellite, terrestrial, cable of CI.
While here, move the TS ID to the bridge code, where it
is used, and change its value, as it was identical to
the value previously used by network ID. While we could
keep the same value, let's change it, just to make easier
to check for the new code while reading it with DVB tools
