de80f95ccb9c ("PCI: cadence: Move all files to per-device cadence
directory") moved files of the PCI cadence drivers, but did not update the
MAINTAINERS entry.
Since then, ./scripts/get_maintainer.pl --self-test complains:
warning: no file matches F: drivers/pci/controller/pcie-cadence*
Repair the MAINTAINERS entry.

maintenance to Thomas Bogendoerfer - this will be my final pull
request as MIPS maintainer.
Thanks for your helpful comments, useful corrections & responsiveness
during the time I've fulfilled the role, and I'm sure I'll pop up
elsewhere in the tree somewhere down the line"

My time with MIPS the company has reached its end, and so at best I'll
have little time spend on maintaining arch/mips/.
Ralf last authored a patch over 2 years ago, the last time he committed
one is even further back & activity was sporadic for a while before
that. The reality is that he isn't active.
Having a new maintainer with time to do things properly will be
beneficial all round. Thomas Bogendoerfer has been involved in MIPS
development for a long time & has offered to step up as maintainer, so
add Thomas and remove myself & Ralf from the MIPS entry.
Ralf already has an entry in CREDITS to honor his contributions, so this
just adds one for me.

Commit e567cb3fef30 ("MAINTAINERS: add an entry for kfifo") added a new
entry to MAINTAINERS. Following the example of the previous entry on the
list I added a trailing ':' character at the end of the title line.
This however results in rather strange looking output from
scripts/get_maintainer.pl:
$ ./scripts/get_maintainer.pl ./0001-kfifo.patch
Stefani Seibold <stefani@seibold.net> (maintainer:KFIFO:)
linux-kernel@vger.kernel.org (open list)
It turns out there are more entries like this. Fix the entire file by
removing all trailing colons.

Pull drm fixes from Dave Airlie:
"Varied fixes for rc3.
i915 is the largest, they are seeing some ACPI problems with their CI
which hopefully get solved soon [1].
msm has a bunch of fixes for new hw added in the merge, a bunch of
amdgpu fixes, and nouveau adds support for some new firmwares for
turing tu11x GPUs that were just released into linux-firmware by
nvidia, they operate the same as the ones we already have for tu10x so
should be fine to hook up.
Otherwise it's just misc fixes for panfrost and sun4i.
core:
- Allow only one rotation argument, and allow zero rotation in video
cmdline.
i915:
- Workaround missing Display Stream Compression (DSC) state readout
by forcing modeset when its enabled at probe
- Fix EHL port clock voltage level requirements
- Fix queuing retire workers on the virtual engine
- Fix use of partially initialized waiters
- Stop using drm_pci_alloc/drm_pci/free
- Fix rewind of RING_TAIL by forcing a context reload
- Fix locking on resetting ring->head
- Propagate our bug filing URL change to stable kernels
panfrost:
- Small compiler warning fix for panfrost.
- Fix when using performance counters in panfrost when using per fd
address space.
sun4xi:
- Fix dt binding
nouveau:
- tu11x modesetting fix
- ACR/GR firmware support for tu11x (fw is public now)
msm:
- fix UBWC on GPU and display side for sc7180
- fix DSI suspend/resume issue encountered on sc7180
- fix some breakage on so called "linux-android" devices
(fallout from sc7180/a618 support, not seen earlier due to
bootloader/firmware differences)
- couple other misc fixes
amdgpu:
- HDCP fixes
- xclk fix for raven
- GFXOFF fixes"

git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs
Pull new zonefs file system from Damien Le Moal:
"Zonefs is a very simple file system exposing each zone of a zoned
block device as a file.
Unlike a regular file system with native zoned block device support
(e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
sequential write constraint of zoned block devices to the user. As a
result, zonefs is not a POSIX compliant file system. Its goal is to
simplify the implementation of zoned block devices support in
applications by replacing raw block device file accesses with a richer
file based API, avoiding relying on direct block device file ioctls
which may be more obscure to developers.
One example of this approach is the implementation of LSM
(log-structured merge) tree structures (such as used in RocksDB and
LevelDB) on zoned block devices by allowing SSTables to be stored in a
zone file similarly to a regular file system rather than as a range of
sectors of a zoned device. The introduction of the higher level
construct "one file is one zone" can help reducing the amount of
changes needed in the application while at the same time allowing the
use of zoned block devices with various programming languages other
than C.
Zonefs IO management implementation uses the new iomap generic code.
Zonefs has been successfully tested using a functional test suite
(available with zonefs userland format tool on github) and a prototype
implementation of LevelDB on top of zonefs"

zonefs is a very simple file system exposing each zone of a zoned block
device as a file. Unlike a regular file system with zoned block device
support (e.g. f2fs), zonefs does not hide the sequential write
constraint of zoned block devices to the user. Files representing
sequential write zones of the device must be written sequentially
starting from the end of the file (append only writes).
As such, zonefs is in essence closer to a raw block device access
interface than to a full featured POSIX file system. The goal of zonefs
is to simplify the implementation of zoned block device support in
applications by replacing raw block device file accesses with a richer
file API, avoiding relying on direct block device file ioctls which may
be more obscure to developers. One example of this approach is the
implementation of LSM (log-structured merge) tree structures (such as
used in RocksDB and LevelDB) on zoned block devices by allowing SSTables
to be stored in a zone file similarly to a regular file system rather
than as a range of sectors of a zoned device. The introduction of the
higher level construct "one file is one zone" can help reducing the
amount of changes needed in the application as well as introducing
support for different application programming languages.
Zonefs on-disk metadata is reduced to an immutable super block to
persistently store a magic number and optional feature flags and
values. On mount, zonefs uses blkdev_report_zones() to obtain the device
zone configuration and populates the mount point with a static file tree
solely based on this information. E.g. file sizes come from the device
zone type and write pointer offset managed by the device itself.
The zone files created on mount have the following characteristics.
1) Files representing zones of the same type are grouped together
under a common sub-directory:
* For conventional zones, the sub-directory "cnv" is used.
* For sequential write zones, the sub-directory "seq" is used.
These two directories are the only directories that exist in zonefs.
Users cannot create other directories and cannot rename nor delete
the "cnv" and "seq" sub-directories.
2) The name of zone files is the number of the file within the zone
type sub-directory, in order of increasing zone start sector.
3) The size of conventional zone files is fixed to the device zone size.
Conventional zone files cannot be truncated.
4) The size of sequential zone files represent the file's zone write
pointer position relative to the zone start sector. Truncating these
files is allowed only down to 0, in which case, the zone is reset to
rewind the zone write pointer position to the start of the zone, or
up to the zone size, in which case the file's zone is transitioned
to the FULL state (finish zone operation).
5) All read and write operations to files are not allowed beyond the
file zone size. Any access exceeding the zone size is failed with
the -EFBIG error.
6) Creating, deleting, renaming or modifying any attribute of files and
sub-directories is not allowed.
7) There are no restrictions on the type of read and write operations
that can be issued to conventional zone files. Buffered, direct and
mmap read & write operations are accepted. For sequential zone files,
there are no restrictions on read operations, but all write
operations must be direct IO append writes. mmap write of sequential
files is not allowed.
Several optional features of zonefs can be enabled at format time.
* Conventional zone aggregation: ranges of contiguous conventional
zones can be aggregated into a single larger file instead of the
default one file per zone.
* File ownership: The owner UID and GID of zone files is by default 0
(root) but can be changed to any valid UID/GID.
* File access permissions: the default 640 access permissions can be
changed.
The mkzonefs tool is used to format zoned block devices for use with
zonefs. This tool is available on Github at:
git@github.com:damien-lemoal/zonefs-tools.git.
zonefs-tools also includes a test suite which can be run against any
zoned block device, including null_blk block device created with zoned
mode.
Example: the following formats a 15TB host-managed SMR HDD with 256 MB
zones with the conventional zones aggregation feature enabled.
$ sudo mkzonefs -o aggr_cnv /dev/sdX
$ sudo mount -t zonefs /dev/sdX /mnt
$ ls -l /mnt/
total 0
dr-xr-xr-x 2 root root 1 Nov 25 13:23 cnv
dr-xr-xr-x 2 root root 55356 Nov 25 13:23 seq
The size of the zone files sub-directories indicate the number of files
existing for each type of zones. In this example, there is only one
conventional zone file (all conventional zones are aggregated under a
single file).
$ ls -l /mnt/cnv
total 137101312
-rw-r----- 1 root root 140391743488 Nov 25 13:23 0
This aggregated conventional zone file can be used as a regular file.
$ sudo mkfs.ext4 /mnt/cnv/0
$ sudo mount -o loop /mnt/cnv/0 /data
The "seq" sub-directory grouping files for sequential write zones has
in this example 55356 zones.
$ ls -lv /mnt/seq
total 14511243264
-rw-r----- 1 root root 0 Nov 25 13:23 0
-rw-r----- 1 root root 0 Nov 25 13:23 1
-rw-r----- 1 root root 0 Nov 25 13:23 2
...
-rw-r----- 1 root root 0 Nov 25 13:23 55354
-rw-r----- 1 root root 0 Nov 25 13:23 55355
For sequential write zone files, the file size changes as data is
appended at the end of the file, similarly to any regular file system.
$ dd if=/dev/zero of=/mnt/seq/0 bs=4K count=1 conv=notrunc oflag=direct
1+0 records in
1+0 records out
4096 bytes (4.1 kB, 4.0 KiB) copied, 0.000452219 s, 9.1 MB/s
$ ls -l /mnt/seq/0
-rw-r----- 1 root root 4096 Nov 25 13:23 /mnt/seq/0
The written file can be truncated to the zone size, preventing any
further write operation.
$ truncate -s 268435456 /mnt/seq/0
$ ls -l /mnt/seq/0
-rw-r----- 1 root root 268435456 Nov 25 13:49 /mnt/seq/0
Truncation to 0 size allows freeing the file zone storage space and
restart append-writes to the file.
$ truncate -s 0 /mnt/seq/0
$ ls -l /mnt/seq/0
-rw-r----- 1 root root 0 Nov 25 13:49 /mnt/seq/0
Since files are statically mapped to zones on the disk, the number of
blocks of a file as reported by stat() and fstat() indicates the size
of the file zone.
$ stat /mnt/seq/0
File: /mnt/seq/0
Size: 0 Blocks: 524288 IO Block: 4096 regular empty file
Device: 870h/2160d Inode: 50431 Links: 1
Access: (0640/-rw-r-----) Uid: ( 0/ root) Gid: ( 0/ root)

Birth: -
The number of blocks of the file ("Blocks") in units of 512B blocks
gives the maximum file size of 524288 * 512 B = 256 MB, corresponding
to the device zone size in this example. Of note is that the "IO block"
field always indicates the minimum IO size for writes and corresponds
to the device physical sector size.

VirtualBox hosts can share folders with guests, this commit adds a
VFS driver implementing the Linux-guest side of this, allowing folders
exported by the host to be mounted under Linux.
This driver depends on the guest <-> host IPC functions exported by
the vboxguest driver.

The justification of a light version of the parport driver was less
overhead for embedded systems. Well, today, even if an embedded system
still has a parport, it surely can handle the fully-fledged parport
driver. Remove it to reduce the maintenance burden.

Pull tracing updates from Steven Rostedt:
- Added new "bootconfig".
This looks for a file appended to initrd to add boot config options,
and has been discussed thoroughly at Linux Plumbers.
Very useful for adding kprobes at bootup.
Only enabled if "bootconfig" is on the real kernel command line.
- Created dynamic event creation.
Merges common code between creating synthetic events and kprobe
events.
- Rename perf "ring_buffer" structure to "perf_buffer"
- Rename ftrace "ring_buffer" structure to "trace_buffer"
Had to rename existing "trace_buffer" to "array_buffer"
- Allow trace_printk() to work withing (some) tracing code.
- Sort of tracing configs to be a little better organized
- Fixed bug where ftrace_graph hash was not being protected properly
- Various other small fixes and clean ups

Extra Boot Config (XBC) allows admin to pass a tree-structured
boot configuration file when boot up the kernel. This extends
the kernel command line in an efficient way.
Boot config will contain some key-value commands, e.g.
key.word = value1
another.key.word = value2
It can fold same keys with braces, also you can write array
data. For example,
key {
word1 {
setting1 = data
setting2
}
word2.array = "val1", "val2"
}
User can access these key-value pair and tree structure via
SKC APIs.
