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.

As comment of device_add() says, if device_add() succeeds, you should
call device_del() when you want to get rid of it. If device_add() has
not succeeded, use only put_device() to drop the reference count.
Add a put_device() call before returning from the function to decrement
reference count for cleanup.

Extend the ODP counters to include the number of times page fault
and invalidation events were handled.
Example for a single page fault handling 512 pages:
- page_fault: incremented by 512 (total pages)
- page_fault_handled: incremented by 1 (operation count)
The same example is applicable for page invalidation too.

Pull i2c component probing support from Wolfram Sang:
"Add OF component probing.
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular
device can be detected by some firmware provided identifier, other
times that information is not available, and the kernel has to try to
probe each device.
Instead of a delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component probe function. For a
given class of devices on the same I2C bus, it will go through all of
them, doing a simple I2C read transfer and see which one of them
responds. It will then enable the device that responds"

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.

- When removing a PCI device, only look up and remove a platform device
if there is an associated device node for which there could be a
platform device, to fix a merge window regression (Brian Norris)

Pull more io_uring updates from Jens Axboe:
- Remove a leftover struct from when the cqwait registered waiting was
transitioned to regions.
- Fix for an issue introduced in this merge window, where nop->fd might
be used uninitialized. Ensure it's always set.
- Add capping of the task_work run in local task_work mode, to prevent
bursty and long chains from adding too much latency.
- Work around xa_store() leaving ->head non-NULL if it encounters an
allocation error during storing. Just a debug trigger, and can go
away once xa_store() behaves in a more expected way for this
condition. Not a major thing as it basically requires fault injection
to trigger it.
- Fix a few mapping corner cases
- Fix KCSAN complaint on reading the table size post unlock. Again not
a "real" issue, but it's easy to silence by just keeping the reading
inside the lock that protects it.

Pull sh updates from John Paul Adrian Glaubitz:
"Two small fixes.
The first one by Huacai Chen addresses a runtime warning when
CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected
which occurs because the cpuinfo code on sh incorrectly uses NR_CPUS
when iterating CPUs instead of the runtime limit nr_cpu_ids.
A second fix by Dan Carpenter fixes a use-after-free bug in
register_intc_controller() which occurred as a result of improper
error handling in the interrupt controller driver code when
registering an interrupt controller during plat_irq_setup() on sh"

Introduce the counter as a part of global, platform counters structure.
We open the counter for only one cpu, but otherwise treat it as an
ordinary RAPL counter, allowing for grouped perf read.
The counter is disabled by default, because it's interpretation may
require additional, platform specific information, making it unsuitable
for general use.

Add '+' to optstring when early scanning for --no-msr and --no-perf.
It causes option processing to stop as soon as a nonoption argument is
encountered, effectively skipping child's arguments.
