Based on panel hardware support, display brightness levels can
be very high value. This high value display brightness cooling
device levels can cause exceeding PAGE_SIZE for cooling device stat
buffer. It leads to buffer failure for cooling device stat feature.
Limit display panel mitigation level max to 255. If hardware
supports more than 255, then scale brightness levels fit
into above limit.

exfat_extract_uni_name copies characters from a given file name entry into
the 'uniname' variable. This variable is actually defined on the stack of
the exfat_readdir() function. According to the definition of
the 'exfat_uni_name' type, the file name should be limited 255 characters
(+ null teminator space), but the exfat_get_uniname_from_ext_entry()
function can write more characters because there is no check if filename
entries exceeds max filename length. This patch add the check not to copy
filename characters when exceeding max filename length.

The call stack shown below is a scenario in the Linux 4.19 kernel.
Allocating memory failed where exfat fs use kmalloc_array due to
system memory fragmentation, while the u-disk was inserted without
recognition.
Devices such as u-disk using the exfat file system are pluggable and
may be insert into the system at any time.
However, long-term running systems cannot guarantee the continuity of
physical memory. Therefore, it's necessary to address this issue.

Consider a scenario in which open, write and close of AT port is being
done repeatedly. At some point in time, cbits_updated in f_cdev
structure gets overwritten by the previous close instance causing the AT
port to go unresponsive. This prevents port bridge service from sending
DTR/RTS settings to at_mdm0 from at_usb0.
Fix this by adding spinlock to synchronise the updation of
ports->cbits_updated field in f_cdev structure.

Convert to struct mnt_idmap.
Last cycle we merged the necessary infrastructure in
256c8aed2b42 ("fs: introduce dedicated idmap type for mounts").
This is just the conversion to struct mnt_idmap.
Currently we still pass around the plain namespace that was attached to a
mount. This is in general pretty convenient but it makes it easy to
conflate namespaces that are relevant on the filesystem with namespaces
that are relevent on the mount level. Especially for non-vfs developers
without detailed knowledge in this area this can be a potential source for
bugs.
Once the conversion to struct mnt_idmap is done all helpers down to the
really low-level helpers will take a struct mnt_idmap argument instead of
two namespace arguments. This way it becomes impossible to conflate the two
eliminating the possibility of any bugs. All of the vfs and all filesystems

In error handling 'free_cluster', before num_alloc clusters allocated,
p_chain->size will not updated and always 0, thus the newly allocated
clusters are not freed.

When allocating a new cluster, exFAT first allocates from the
next cluster of the last cluster of the file. If the last cluster
of the file is the last cluster of the volume, allocate from the
first cluster. This is a normal case, but the following error log
will be printed. It makes users confused, so this commit removes
the error log.

In the removed code, num_clusters is 0, nothing is done in
exfat_chain_cont_cluster(), so it is unneeded, remove it.

Patch series "start removing writepage instances v2".
The VM doesn't need or want ->writepage for writeback and is fine with
just having ->writepages as long as ->migrate_folio is implemented.
This series removes all ->writepage instances that use
block_write_full_page directly and also have a plain mpage_writepages
based ->writepages.
This patch (of 7):
->writepage is a very inefficient method to write back data, and only used
through write_cache_pages or a a fallback when no ->migrate_folio method
is present.
Set ->migrate_folio to the generic buffer_head based helper, and remove
the ->writepage implementation.
