mm: memcontrol: Add force_reclaim to reclaim tasks' memory in memcg
These days, platforms tend to manage memory on low memory state
like andloid's lowmemory killer. These platforms might want to
reclaim memory from background tasks as well as kill victims
to guarantee free memory at use space level. This patch provides
an interface to reclaim a given memcg. After platform's low memory
handler moves tasks that the platform wants to reclaim to
a memcg and decides how many pages should be reclaimed, it can
reclaim the pages from the tasks by writing the number of pages
at memory.force_reclaim.

mm: LKSM: new feature: use filter-based scanning to reduce scanning cost
LKSM_FILTER is a new feature which is intended to reduce the computation cost.
LKSM_FILTER exploits bitmap-based filters to skip scanning of unnecessary
pages. To this end, LKSM collects addresses of shared pages to make filters.
The rationale of LKSM_FILTER is that user-level programs share common runtime
framework and libraries. Because of that processes can have similar address
space layout. It means that if a page is merged with another page, the same
virtual address in different process can be merged with this merged page.
In this regard, KSM can use a single global filter to cover all sharable areas
in the system.
The challenge is caused by a secure construct of Linux kernel, namely ASLR.
ASLR enforces to have randomized address space for each process, and it
severely disrupts making a global filter.
To overcome this challenge, LKSM exploits two information: regions and offsets.
A region means the physically mapped area. Each process has its own VMAs but
they may mapped same files. A region means the original one.
An address space of a process is randomized in the unit of VMA. It means that
if pages are merged even in the different virtual addresses, there can be at
same offsets from individual VMAs.
LKSM leverages both regions and offsets to construct per-region filters.
By using per-region filters, LKSM could effectively reduce its scanning space
and also computation cost by up to 46% against previous version of LKSM at the
expense of somewhat sharing chances.

mm: LKSM: lightweight memory deduplication for embedded devices
Lightweight KSM (in short, LKSM) is a variant of KSM that is implemented in
a fully event-triggered manner. LKSM provides a memory deduplication facility
like vanilla KSM while it extremely reduces overhead.
Normally, LKSM is blocked and waits for incoming deduplication requests from
user-level process (e.g., resourced). When a user-level process submits
deduplication request via sysfs, LKSM performs requested-level of deduplication,
such as partial and full deduplications.
After that, LKSM is going to sleep again and waits for next request coming.
By doing so, LKSM mitigates side effects that impact on system performance,
for instance, occupying system resources such as CPU and incurring cache
pollutions.

Bluetooth: hci_bcm: Fix RTS handling during startup
commit
3347a80965b38f096b1d6f995c00c9c9e53d4b8b upstream.
The RPi 4 uses the hardware handshake lines for CYW43455, but the chip
doesn't react to HCI requests during DT probe. The reason is the inproper
handling of the RTS line during startup. According to the startup
signaling sequence in the CYW43455 datasheet, the hosts RTS line must
be driven after BT_REG_ON and BT_HOST_WAKE.

resetting it if zram is once initialized by setting disksize. Since
this, however, zram can have multiple compressor and switch them

With this, zram uses the algorithm which is fast but has low
compression ratio at first, and can change to the one that is slightly
slower but having higher ratio when the target get bothered by low

LOCAL / Revert "drm/vc4: Allocate binner bo when starting to use the V3D"
This reverts commit
35c8b4b2c0fed637d2b30a8ec8e5d7f4c19c8d9d.
If we use drm-vc4 and drm-v3d driver without using vc4->v3d driver,
drm-vc4 bo is not created. In this case, it is RPI4. The RPI4 uses
drm-v3d when using GL. So revert this patch until the problem is
resolved.

usb: dwc2: gadget: Expand buffer size of control endpoint
We found the case that buffer of control endpoint, which was allocated
with 8 bytes previously, is corrupted when the host races for setting
up interfaces. Even worse, it overwrites memory for other structure
such as usb_request for control endpoint and it causes kernel panic.
Especially in Tizen, it often happens when the target is configured as
multi-functional device: sdb + mtp.
In our emprical examination the buffer can be corrupted upto size of
456 bytes. With this result, the size of buffer will be enlarged to
512 bytes to prevent kernel panic even if it happens.
