bnxt_en: Add ULP call to notify async events
When the driver receives an async event notification from the Firmware,
we make the new ulp_async_notifier() call to inform the RDMA driver that
a firmware async event has been received. RDMA driver can then take
necessary actions based on the event type.
In the next patch, we will implement the ulp_async_notifier() callbacks

RDMA/mlx5: Fix indirect mkey ODP page count
Restrict the check for the number of pages handled during an ODP page
fault to direct mkeys.
Perform the check right after handling the page fault and don't
propagate the number of handled pages to callers.
Indirect mkeys and their associated direct mkeys can have different
start addresses. As a result, the calculation of the number of pages to
handle for an indirect mkey may not match the actual page fault
handling done on the direct mkey.
For example:
A 4K sized page fault on a KSM mkey that has a start address that is not
aligned to a page will result a calculation that assumes the number of
pages required to handle are 2.
While the underlying MTT might be aligned will require fetching only a
single page.
Thus, do the calculation and compare number of pages handled only per
direct mkey.

RDMA/core: Support link status events dispatching
Currently the dispatching of link status events is implemented by
each RDMA driver independently, and most of them have very similar
patterns. Add support for this in ib_core so that we can get rid
of duplicate codes in each driver.
A new last_port_state is added in ib_port_cache to cache the port
state of the last link status events dispatching. The original
port_state in ib_port_cache is not used here because it will be
updated when ib_dispatch_event() is called, which means it may
be changed between two link status events, and may lead to a loss
of event dispatching.
Some drivers currently have some private stuff in their link status
events handler in addition to event dispatching, and cannot be
perfectly integrated into the ib_core handling process. For these
drivers, add a new ops report_port_event() so that they can keep
their current processing.
Finally, events of LAG devices are not supported yet in this patch
as currently there is no way to obtain ibdev from upper netdev in
ib_core. This can be a TODO work after the core have more support
for LAG.

strscpy: write destination buffer only once
The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.
So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination. But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.
It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).
Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer). Otherwise it returns the string length of the
result.
However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.
In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.
Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.
[ Note that "final byte is NUL" here is literally about the final byte
in the destination array, not the terminating NUL at the end of the
string itself. There is no attempt to try to make concurrent reads and
writes give any kind of consistent string length or contents, but we
do want to guarantee that there is always at least that final
terminating NUL character at the end of the destination array if it
existed before ]
This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).
So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

tools/power turbostat: Enhance platform divergence description
In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.
To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.

PCI/pwrctrl: Unregister platform device only if one actually exists
If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl. When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.
But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL". The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.
Unregister a platform device only if there is one associated with this PCI
device. This resolves issues seen when doing:
# echo 1 > /sys/bus/pci/devices/.../remove
Sample issue from unregistering the wrong platform device:
