83ba7361e1 of: reserved_mem: Try to keep range allocations contiguous
Right now dynamic reserved memory regions are allocated either
bottom-up or top-down, depending on the memblock setting of the
architecture. This is fine when the address is arbitrary. However,
when using "alloc-ranges" the regions are often placed somewhere
in the middle of (free) RAM, even if the range starts or ends next
to another (static) reservation.

Try to detect this situation, and choose explicitly between bottom-up
or top-down to allocate the memory close to the other reservations:

  1. If the "alloc-range" starts at the end or inside an existing
     reservation, use bottom-up.
  2. If the "alloc-range" ends at the start or inside an existing
     reservation, use top-down.
  3. If both or none is the case, keep the current
     (architecture-specific) behavior.

There are plenty of edge cases where only a more complex algorithm
would help, but even this simple approach helps in many cases to keep
the reserved memory (and therefore also the free memory) contiguous.

800e75245b dt-bindings: Remove last usage of "binding" or "schema" in titles
The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding", but instead just describe the hardware.

Most of these have been fixed already, so fix the handful that snuck in.
With this, a meta-schema check can be enabled to catch these
automatically.

96b2b1a279 dt-bindings: display: panel: mipi-dbi-spi: add shineworld lh133k compatible
The Shineworld LH133K is a 1.3" 240x240px RGB LCD with a MIPI DBI
compatible SPI interface.
The initialization procedure is quite basic with the exception of
requiring inverted colors.
A basic mipi-dbi-cmd[1] script to get the display running thus looks
like this:

    $ cat shineworld,lh133k.txt
    command 0x11 # exit sleep mode
    delay 120

    # The display seems to require display color inversion, so enable it.
    command 0x21 # INVON

    # Enable normal display mode (in contrast to partial display mode).
    command 0x13 # NORON
    command 0x29 # MIPI_DCS_SET_DISPLAY_ON

    $ mipi-dbi-cmd shineworld,lh133k.bin shineworld,lh133k.txt

2220eaf909 ext4: add bounds checking in get_max_inline_xattr_value_size()
Normally the extended attributes in the inode body would have been
checked when the inode is first opened, but if someone is writing to
the block device while the file system is mounted, it's possible for
the inode table to get corrupted.  Add bounds checking to avoid
reading beyond the end of allocated memory if this happens.

f4ce24f54d ext4: fix deadlock when converting an inline directory in nojournal mode
In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock
by calling ext4_handle_dirty_dirblock() when it already has taken the
directory lock.  There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.

A simple reproducer demonstrating the problem:

    mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
    mount -t ext4 -o dirsync /dev/vdc /vdc
    cd /vdc
    mkdir file0

4c0b4818b1 ext4: improve error recovery code paths in __ext4_remount()
If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.

This commit fixes two problem.  The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free.  The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

4b3cb1d108 ext4: improve error handling from ext4_dirhash()
The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced.  However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.

So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.

a44be64bbe ext4: don't clear SB_RDONLY when remounting r/w until quota is re-enabled
When a file system currently mounted read/only is remounted
read/write, if we clear the SB_RDONLY flag too early, before the quota
is initialized, and there is another process/thread constantly
attempting to create a directory, it's possible to trigger the

	WARN_ON_ONCE(dquot_initialize_needed(inode));

in ext4_xattr_block_set(), with the following stack trace:
