10208567f1 f2fs: introduce max_io_bytes, a sysfs entry, to limit bio size
This patch adds max_io_bytes to limit bio size when f2fs tries to merge
consecutive IOs. This can give a testing point to split out bios and check
end_io handles those bios correctly. This is used to capture a recent bug
on the decompression and fsverity flow.

5e38884152 rtw88: declare hw supports ch 144
When driver was developed, FCC regulation didn't enable channel 144
and there was no demand for channel 144 at that time. Although HW
actually supports channel 144, driver didn't announce channel 144.
Therefore, channel 144 (20 MHz), channel 142 (40 MHz) and channel
138 (80 MHz) couldn't be used.

Today, channel 144 has been enabled by regulations and
is gradually being supported. With test requirements,
we declare hw supports channel 144.

01b660b87e mwl8k: switch from 'pci_' to 'dma_' API
he wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'mwl8k_rxq_init()' and 'mwl8k_txq_init()'
GFP_KERNEL can be used because this flag is already used in a 'kcalloc()'
call, just a few line below.

When memory is allocated in 'mwl8k_firmware_load_success()' GFP_KERNEL can
be used because this flag is already used within 'ieee80211_register_hw()'
which is called just a few line below.

f34a32fae7 platform/x86/drivers/acerhdf: Check the interval value when it is set
Currently the code checks the interval value when the temperature is
read which is bad for two reasons:

 - checking and setting the interval in the get_temp callback is
   inaccurate and awful, that can be done when changing the value.

 - Changing the thermal zone structure internals is an abuse of the
   exported structure, moreover no lock is taken here.

The goal of this patch is to solve the first item by using the 'set'
function called when changing the interval. The check is done there
and removed from the get_temp function. If the thermal zone was not
initialized yet, the interval is not updated in this case as that will
happen in the init function when registering the thermal zone device.

I don't have any hardware to test the changes.

a4327979a1 platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on some HP x360 models
Some HP x360 models have an ACPI VGBS method which sets bit 4 instead of
bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT
collection shows only one other model, the Medion E1239T ever setting bit 4
and it always sets this together with bit 6.

So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.

While at it also prefix all VGBS constant defines with "VGBS_".

Note this wrokaround was first added to the kernel as
commit d823346876 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always
reporting 1 on the HP Pavilion 11 x360").
After commit 8169bd3e6e ("platform/x86: intel-vbtn: Switch to an
allow-list for SW_TABLET_MODE reporting") got added to the kernel this
was reverted, because with the new allow-list approach the workaround
was no longer necessary for the model on which the issue was first
reported.

But it turns out that the workaround is still necessary because some
affected models report a chassis-type of 31 which is on the allow-list.

8b105ef6ff acer-wireless: send an EV_SYN/SYN_REPORT between state changes
Sending the switch state change twice within the same frame is invalid
evdev protocol and only works if the client handles keys immediately as
well. Processing events immediately is incorrect, it forces a fake
order of events that does not exist on the device.

Recent versions of libinput changed to only process the device state and
SYN_REPORT time, so now the key event is lost.

Same fix as 'commit <bff5bf9db1c94> ("platform/x86: asus-wireless: send

0671c06623 Bluetooth: btusb: Add workaround for remote-wakeup issues with Barrot 8041a02 fake CSR controllers
With the recent btusb change to detect and deal with more fake CSR
controllers, I decided to see if fake CSR controllers with Barrot
8041a02 chips would now work.

After much experimentation I came to the conclusion that it works, if I
have autosuspend enabled initially and then disable it after the device
has suspended at least once. Yes this is very weird, but I've tried many
things, like manually clearing the remote-wakeup feature. Doing a
runtime-resume + runtime suspend is the only way to get the receiver
to actually report received data (and/or pairing info) through its
bulk rx endpoint.

But the funkyness of the bulk-endpoint does not stop there, I mainly
found out about this problem, because with autosuspend enabled
(which usually ensures the suspend at least once condition is met),
the receiver stops reporting received data through its bulk rx endpoint
as soon as autosuspend kicks in. So I initially just disabled
autosuspend, but then the receiver does not work at all.

This was with a fake CSR receiver with a Barrot 8041a02 chip with a
bcdDevice value of 0x8891, a lmp_subver of 0x1012, a hci_rev of 0x0810
and a hci_ver of BLUETOOTH_VER_4_0.

Summarizing this specific fake CSR receiver has the following 2 issues:

1. The bulk rx endpoint will never report any data unless
the device was suspended at least once.

2. They will not wakeup when autosuspended and receiving data on their
bulk rx endpoint from e.g. a keyboard or mouse (IOW remote-wakeup support
is broken for the bulk endpoint).

Add a workaround for 1. which enables runtime-suspend, force-suspends
the hci and then wakes-it up by disabling runtime-suspend again.

Add a workaround for 2. which clears the hci's can_wake flag, this way
the hci will still be autosuspended when it is not open.

Commit cde1a8a992 ("Bluetooth: btusb: Fix and detect most of the

more generic fixing it for much of the newer fakes / clones.

But this does not work for a fake CSR controller with a bcdDevice
value of 0x0134, which was correctly identified as fake before
this change.

Add an extra check for this special case, checking for a combination
of a bcdDevice value of 0x0134, together with a lmp_subver of 0x0c5c
and a hci_ver of BLUETOOTH_VER_2_0.

The chip inside this fake dongle is marked as with "clockwise cw6629d".

This patch takes the min/max intervals and tx power optionally provided
in mgmt interface, stores them in the advertisement struct, and uses
them when configuring the hci requests. While tx power is not used if
extended advertising is unavailable, software rotation will use the min
and max advertising intervals specified by the client.

This change is validated manually by ensuring the min/max intervals are
propagated to the controller on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks, and that tx power is
propagated correctly on hatch. These tests are performed with multiple
advertisements simultaneously.
