Value CRSM_SFT_PD written to Software Power-Down Control Register
(CRSM_SFT_PD_CNTRL) is 0x01 and therefor different to value
CRSM_SFT_PD_RDY (0x02) read from System Status Register (CRSM_STAT) for

The condition could have only worked when disabling powerdown
(both 0x00), but never when enabling it (0x01 != 0x02).

====================
net: stmmac: simplify axi_blen handling
stmmac's axi_blen (burst length) handling is very verbose and
unnecessary.
Firstly, the burst length register bitfield is the same across all
dwmac cores, so we can use common definitions for these bits which
platform glue can use.
We end up with platform glue:
- filling in the axi_blen[] array with the decimal burst lengths, e.g.
dwmac-intel.c, etc
- decoding a bitmap into burst lengths for this array, e.g.
dwmac-dwc-qos-eth.c
Other cases read the array from DT, placing it into the axi_blen
array, and converting later to the register bitfield.
This series removes all this complexity, ultimately ending up with
platform glue providing the register value containing the burst
length bitfield directly. Where necessary, platform glue calls
stmmac_axi_blen_to_mask() to convert a decimal array (e.g. from
DT) to the register value.
This also means that stmmac_axi_blen_to_mask() can issue a
diagnostic message at probe time if the burst length is incorrect.

Remove the axi_blen array from struct stmmac_axi as we set this array,
and then immediately convert it ot the register value, never looking at

Simplify the switch() statement in dwc_eth_dwmac_config_dt().
Although this is not speed-critical, simplifying it can make it more
readable. This also drastically improves the code emitted by the
compiler.
On aarch64, with the original code, the compiler loads registers with
every possible value, and then has a tree of test-and-branch statements
to work out which register to store. With the simplified code, the
compiler can load a register with '4' and shift it appropriately.
This shrinks the text size on aarch64 from 4289 bytes to 4153 bytes,
a reduction of 3%.

A VFS cache inconsistency, potentially triggered by sequences like
buffered writes followed by open(O_DIRECT), can result in an invalid
on-disk inode block (e.g., bad signature). OCFS2 detects this corruption
when reading the inode block via ocfs2_validate_inode_block(), logs
"Invalid dinode", and often switches the filesystem to read-only mode.
The VFS open(O_DIRECT) operation appears to incorrectly clear the inode's
I_DIRTY flag without ensuring the dirty metadata (reflecting the earlier
buffered write, e.g., an updated i_size) is flushed to disk. This leaves
the in-memory VFS inode object "in limbo" with an updated size (e.g.,
38639 from the write) but marked clean, while its on-disk counterpart
remains stale (e.g., size 0) or invalid.
Currently, the function reading the inode block
(ocfs2_read_inode_block_full()) fails to call make_bad_inode() upon
detecting the validation error. Because the in-memory inode is not marked
bad, subsequent operations (like ftruncate) proceed erroneously. They
eventually reach code (e.g., ocfs2_truncate_file()) that compares the
inconsistent in-memory size (38639) against the invalid/stale on-disk size
(0), leading to kernel crashes via BUG_ON.
Fix this by calling make_bad_inode(inode) within the error handling path
of ocfs2_read_inode_block_full() immediately after a block read or
validation error occurs. This ensures VFS is properly notified about the
corrupt inode at the point of detection. Marking the inode bad allows VFS
to correctly fail subsequent operations targeting this inode early,
preventing kernel panics caused by operating on known inconsistent inode
states.

strcpy() has been deprecated [1] because it performs no bounds checking on
the destination buffer, which can lead to buffer overflows. Replace it
with the safer strscpy(), and copy directly into '->rf_signature' instead
of using the start of the struct as the destination buffer.

Corrects a spelling mistake in a comment in ratelimit.c where 'seperately'
was used instead of 'separately'.

Petr has been actively reviewing hung task detector patches lately. It's
always good to have a fresh pair of eyes, so let's make it official.
I checked with him, and he's happy to be added.

These methods only exist when INLINE_COPY_FROM_USER is disabled, so update
the header file to reflect that.
This fixes the following error on builds that enable both RUST and
INLINE_COPY_FROM_USER.
ERROR: modpost: "_copy_from_user" [samples/rust/rust_misc_device.ko] undefined!
ERROR: modpost: "_copy_to_user" [samples/rust/rust_misc_device.ko] undefined!
This error is triggered because when a method is available both as a
rust_helper_* and normal method, Rust will call the normal method.
[akpm@linux-foundation.org: s/INLINE_COPY_FROM_USER/INLINE_COPY_TO_USER/, per Alice]
