Add suspend/resume platform operations, which, when populated, override
the init/exit platform operations when we suspend and resume. These
suspend()/resume() methods are called by core code, and thus are
designed to support any struct device, not just platform devices. This
allows them to be used by the PCI drivers we have.

netconsole: reuse netpoll_parse_ip_addr in configfs helpers
This patchset refactors the IP address parsing logic in the netconsole
driver to eliminate code duplication and improve maintainability. The
changes centralize IPv4 and IPv6 address parsing into a single function
(netpoll_parse_ip_addr). For that, it needs to teach
netpoll_parse_ip_addr() to handle strings with newlines, which is the
type of string coming from configfs.
Background
The netconsole driver currently has duplicate IP address parsing logic
in both local_ip_store() and remote_ip_store() functions. This
duplication increases the risk of inconsistencies and makes the code
harder to maintain.
Benefits
* Reduced code duplication: ~40 lines of duplicate parsing logic
eliminated
* Improved robustness: Centralized parsing reduces the chance
of inconsistencies
* Easier to maintain: Code follow more the netdev way

Replace manual IP address parsing with a call to netpoll_parse_ip_addr

The error message got removed, since it is not a good practice to

The current IP address parsing logic fails when the input string
contains a trailing newline character. This can occur when IP
addresses are provided through configfs, which contains newlines in
a const buffer.
Teach netpoll_parse_ip_addr() how to ignore newlines at the end of the
IPs. Also, simplify the code by:
* No need to check for separators. Try to parse ipv4, if it fails try
ipv6 similarly to ceph_pton()
* If ipv6 is not supported, don't call in6_pton() at all.

The get_next_frame() function in psock_tpacket.c was missing a return
statement in its default switch case, leading to a compiler warning.
This was caused by a `bug_on(1)` call, which is defined as an
`assert()`, being compiled out because NDEBUG is defined during the
build.
Instead of adding a `return NULL;` which would silently hide the error
and could lead to crashes later, this change restores the original
author's intent. By adding `#undef NDEBUG` before including <assert.h>,
we ensure the assertion is active and will cause the test to abort if
this unreachable code is ever executed.

The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>`
header, is a GNU extension and not universally available with all
toolchains, such as Clang when used with musl libc.
This can lead to build failures in environments where this header is
missing.
The intention of the code is to determine the bit width of a C `long`.
Replace the non-portable `__WORDSIZE` with the standard and portable
`sizeof(long) * 8` expression to achieve the same result.
This change also removes the inclusion of the now-unused
`<bits/wordsize.h>` header.

Since KFD proc content was moved to kernel debugfs, we can't destroy KFD
debugfs before kfd_process_destroy_wq. Move kfd_process_destroy_wq prior
to kfd_debugfs_fini to fix a kernel NULL pointer problem. It happens
when /sys/kernel/debug/kfd was already destroyed in kfd_debugfs_fini but
kfd_process_destroy_wq calls kfd_debugfs_remove_process. This line
debugfs_remove_recursive(entry->proc_dentry);
tries to remove /sys/kernel/debug/kfd/proc/<pid> while
/sys/kernel/debug/kfd is already gone. It hangs the kernel by kernel

If we log a new inode (not persisted in a past transaction) that has 0
links and extents, then log another inode with an higher inode number, we
end up with failing to replay the log tree with -EINVAL. The steps for
this are:
1) create new file A
2) write some data to file A
3) open an fd on file A
4) unlink file A
5) fsync file A using the previously open fd
6) create file B (has higher inode number than file A)
7) fsync file B
8) power fail before current transaction commits
Now when attempting to mount the fs, the log replay will fail with
-ENOENT at replay_one_extent() when attempting to replay the first
extent of file A. The failure comes when trying to open the inode for
file A in the subvolume tree, since it doesn't exist.
Before commit 5f61b96159 ("btrfs: fix inode lookup error handling
during log replay"), the returned error was -EIO instead of -ENOENT,
since we converted any errors when attempting to read an inode during
log replay to -EIO.
The reason for this is that the log replay procedure fails to ignore
the current inode when we are at the stage LOG_WALK_REPLAY_ALL, our
current inode has 0 links and last inode we processed in the previous
stage has a non 0 link count. In other words, the issue is that at
replay_one_extent() we only update wc->ignore_cur_inode if the current
replay stage is LOG_WALK_REPLAY_INODES.
Fix this by updating wc->ignore_cur_inode whenever we find an inode item
regardless of the current replay stage. This is a simple solution and easy
to backport, but later we can do other alternatives like avoid logging
extents or inode items other than the inode item for inodes with a link
count of 0.
The problem with the wc->ignore_cur_inode logic has been around since
commit f2d72f42d5 ("Btrfs: fix warning when replaying log after fsync
of a tmpfile") but it only became frequent to hit since the more recent
commit 5e85262e54 ("btrfs: fix fsync of files with no hard links not
persisting deletion"), because we stopped skipping inodes with a link
count of 0 when logging, while before the problem would only be triggered
if trying to replay a log tree created with an older kernel which has a
logged inode with 0 links.
A test case for fstests will be submitted soon.

- Cleanup whitespace in messages in libata-core and the pata_pdc2027x,
pata_macio drivers (Colin).
- Fix ata_to_sense_error() to avoid seeing nonsensical sense data for
rare cases where we fail to get sense data from the drive. The
complementary fix to this is to ensure that we always return the
generic "ABORTED COMMAND" sense data for a failed command for which
we have no status or error fields.
- The recent changes to link power management (LPM) which now prevent
the user from attempting to set an LPM policy through the
link_power_management_policy caused some regressions in test
environments because of the error that is now returned when writing
to that attribute when LPM is not supported. To allow users to not
trip on this, introduce the new link_power_management_supported
attribute to allow simple testing of a port/device LPM support (me).

The venus driver fails to check if dev_pm_opp_find_freq_{ceil,floor}()
returns an error pointer before calling dev_pm_opp_put(). This causes
a crash when OPP tables are not present in device tree.
Unable to handle kernel access to user memory outside uaccess routines
at virtual address 000000000000002e
...
pc : dev_pm_opp_put+0x1c/0x4c
lr : core_clks_enable+0x4c/0x16c [venus_core]
Add IS_ERR() checks before calling dev_pm_opp_put() to avoid
dereferencing error pointers.

reference count leaks which are caused by:
- VMA splits, which change the offset or size of a mapping, which causes
perf_mmap_close() to ignore the unmap or unmap the wrong buffer.
- Several internal issues of perf_mmap(), which can cause reference count
leaks in the perf mmap, corrupt accounting or cause leaks in perf
drivers.
The main fix is to prevent VMA splits by implementing the [may_]split()
callback for vm operations. The other issues are addressed by rearranging
code, early returns on failure and invocation of cleanups.
Also provide a selftest to validate the fixes.
The reference counting should be converted to refcount_t, but that requires
larger refactoring of the code and will be done once these fixes are
upstream.
