Nearly all other firmware environments have some way of passing a RNG
seed to initialize the RNG: DTB's rng-seed, EFI's RNG protocol, m68k's
bootinfo block, x86's setup_data, and so forth. This adds something
similar for MIPS, which will allow various firmware environments,
bootloaders, and hypervisors to pass an RNG seed to initialize the
kernel's RNG.

We enable -Wcast-function-type globally in the kernel to warn about
mismatching types in function pointer casts. Compilers currently
warn only about ABI incompability with this flag, but Clang 16 will
enable a stricter version of the check by default that checks for an
exact type match. This will be very noisy in the kernel, so disable
-Wcast-function-type-strict without W=1 until the new warnings have
been addressed.

Hans reported that his Sony VAIO VPX11S1E showed the broken sound
behavior at the start of the stream for a couple of seconds, and it
turned out that the position_fix=1 option fixes the issue. It implies
that the position reporting is inaccurate, and very likely hitting on
all Poulsbo devices.
The patch applies the workaround for Poulsbo generically to switch to
LPIB mode instead of the default position buffer.

Counterintuitively, mod_timer(..., jiffies + 1) will cause the timer to
fire not in the next jiffy, but in two jiffies. The way to cause
the timer to fire in the next jiffy is with mod_timer(..., jiffies).
Doing so then lets us bump the upper bound back up again.

As announced on the kvmarm list, we're moving the mailing list over
to kvmarm@lists.linux.dev:
<quote>
As you probably all know, the kvmarm mailing has been hosted on
Columbia's machines for as long as the project existed (over 13
years). After all this time, the university has decided to retire the
list infrastructure and asked us to find a new hosting.
A new mailing list has been created on lists.linux.dev[1], and I'm
kindly asking everyone interested in following the KVM/arm64
developments to start subscribing to it (and start posting your
patches there). I hope that people will move over to it quickly enough
that we can soon give Columbia the green light to turn their systems
off.
Note that the new list will only get archived automatically once we
fully switch over, but I'll make sure we fill any gap and not lose any
message. In the meantime, please Cc both lists.

The HDMI driver skips the notification handling from the graphics
driver when the codec driver is being in the PM operation. This
behavior was introduced by the commit eb399d3c99d8 ("ALSA: hda - Skip
ELD notification during PM process"). This skip may cause a problem,
as we may miss the ELD update when the connection/disconnection
happens right at the runtime-PM operation of the audio codec.
Although this workaround was valid at that time, it's no longer true;
the fix was required just because the ELD update procedure needed to
wake up the audio codec, which had lead to a runtime-resume during a
runtime-suspend. Meanwhile, the ELD update procedure doesn't need a
codec wake up any longer since the commit 788d441a164c ("ALSA: hda -
Use component ops for i915 HDMI/DP audio jack handling"); i.e. there
is no much reason for skipping the notification.
Let's drop those checks for addressing the missing notification.

Convert the hid-over-i2c binding to DT schema format. The supplies should
probably be specific to a specific device, but it seems they are already
in use otherwise. 'wakeup-source' is added as it was not explicitly
documented.
There's a few warnings for undocumented properties 'vcc-supply' and
'reset-gpios'. Those remain as they probably should have a specific
compatible as well.

The 'cantfind_ext4' error handler is just a error msg print and then
goto failed_mount. This two level goto makes the code complex and not
easy to read. The only benefit is that is saves a little bit code.
However some branches can merge and some branches dot not even need it.
So do some refactor and remove it.

Before these two branches neither loaded the journal nor created the
xattr cache. So the right label to goto is 'failed_mount3a'. Although
this did not cause any issues because the error handler validated if the
pointer is null. However this still made me confused when reading
the code. So it's still worth to modify to goto the right label.

Following process may lead to fs corruption:
1. ext4_create(dir/foo)
ext4_add_nondir
ext4_add_entry
ext4_dx_add_entry
a. add_dirent_to_buf
ext4_mark_inode_dirty
ext4_handle_dirty_metadata // dir inode bh is recorded into journal
b. ext4_append // dx_get_count(entries) == dx_get_limit(entries)
ext4_bread(EXT4_GET_BLOCKS_CREATE)
ext4_getblk
ext4_map_blocks
ext4_ext_map_blocks
ext4_mb_new_blocks
dquot_alloc_block
dquot_alloc_space_nodirty
inode_add_bytes // update dir's i_blocks
ext4_ext_insert_extent
ext4_ext_dirty // record extent bh into journal
ext4_handle_dirty_metadata(bh)
// record new block into journal
inode->i_size += inode->i_sb->s_blocksize // new size(in mem)
c. ext4_handle_dirty_dx_node(bh2)
// record dir's new block(dx_node) into journal
d. ext4_handle_dirty_dx_node((frame - 1)->bh)
e. ext4_handle_dirty_dx_node(frame->bh)
f. do_split // ret err!
g. add_dirent_to_buf
ext4_mark_inode_dirty(dir) // update raw_inode on disk(skipped)
2. fsck -a /dev/sdb
drop last block(dx_node) which beyonds dir's i_size.
/dev/sdb: recovering journal
/dev/sdb contains a file system with errors, check forced.
/dev/sdb: Inode 12, end of extent exceeds allowed value
(logical block 128, physical block 3938, len 1)
3. fsck -fn /dev/sdb
dx_node->entry[i].blk > dir->i_size
Pass 2: Checking directory structure
Problem in HTREE directory inode 12 (/dir): bad block number 128.
Clear HTree index? no
Problem in HTREE directory inode 12: block #3 has invalid depth (2)
Problem in HTREE directory inode 12: block #3 has bad max hash
Problem in HTREE directory inode 12: block #3 not referenced
Fix it by marking inode dirty directly inside ext4_append().

ext4_inline_data_fiemap() has been removed since
commit d3b6f23f7167 ("ext4: move ext4_fiemap to use iomap framework"),
so remove it.

ext4 currently updates the i_version counter when the atime is updated
during a read. This is less than ideal as it can cause unnecessary cache
invalidations with NFSv4 and unnecessary remeasurements for IMA.
The increment in ext4_mark_iloc_dirty is also problematic since it can
corrupt the i_version counter for ea_inodes. We aren't bumping the file
times in ext4_mark_iloc_dirty, so changing the i_version there seems
wrong, and is the cause of both problems.
Remove that callsite and add increments to the setattr, setxattr and
ioctl codepaths, at the same times that we update the ctime. The
i_version bump that already happens during timestamp updates should take
care of the rest.
In ext4_move_extents, increment the i_version on both inodes, and also
add in missing ctime updates.
[ Some minor updates since we've already enabled the i_version counter
unconditionally already via another patch series. -- TYT ]

Commit 307af6c87937 ("mbcache: automatically delete entries from cache
on freeing") started nesting cache->c_list_lock under the bit locks
protecting hash buckets of the mbcache hash table in
mb_cache_entry_create(). This causes problems for real-time kernels
because there spinlocks are sleeping locks while bitlocks stay atomic.
Luckily the nesting is easy to avoid by holding entry reference until
the entry is added to the LRU list. This makes sure we cannot race with
entry deletion.

LIFO wakeup order is unfair and sometimes leads to a journal
user not being able to get a journal handle for hundreds of
transactions in a row.
FIFO wakeup can make things more fair.
