MAINTAINERS: notify the "Device Memory" community of memory hotplug changes

The recent episode of a warning regression in memremap_pages() [1]
highlights that relevant updates are being missed by folks that care about
core ZONE_DEVICE changes. Yes, CXL folks should pay more attention to
linux-mm@, but it also would not hurt to copy linux-cxl@, where most
Device Memory folks hang out, on memory hotplug changes by default.

Pull tracing fixes from Steven Rostedt:

- Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS
file

Updates to the tracepoint.rst document should be reviewed by the
tracing maintainers.

- Fix warning triggered by perf attaching to synthetic events

The synthetic events do not add a function to be registered when perf
attaches to them. This causes a warning when perf registers a
synthetic event and passes a NULL pointer to the tracepoint register
function.

Ideally synthetic events should be updated to work with perf, but as
that's a feature and not a bug fix, simply now return -ENODEV when
perf tries to register an event that has a NULL pointer for its
function. This no longer causes a kernel warning and simply causes
the perf code to fail with an error message.

- Fix 32bit overflow in option flag test

The option's flags changed from 32 bits in size to 64 bits in size.
Fix one of the places that shift 1 by the option bit number to to be
1ULL.

- Fix the output of printing the direct jmp functions

The enabled_functions that shows how functions are being attached by
ftrace wasn't updated to accommodate the new direct jmp trampolines
that set the LSB of the pointer, and outputs garbage. Update the
output to handle the direct jmp trampolines.

Florian Westphal says:

====================
netfilter: updates for net

The following patchset contains Netfilter fixes for *net*:

1) Jozsef Kadlecsik is retiring. Fortunately Jozsef will still keep an
eye on ipset patches.

2) remove a bogus direction check from nat core, this caused spurious
flakes in the 'reverse clash' selftest, from myself.

3) nf_tables doesn't need to do chain validation on register store,
from Pablo Neira Ayuso.

4) nf_tables shouldn't revisit chains during ruleset (graph) validation
if possible. Both 3 and 4 were slated for -next initially but there
are now two independent reports of people hitting soft lockup errors
during ruleset validation, so it makes no sense anymore to route
this via -next given this is -stable material. From myself.

5) call cond_resched() in a more frequently visited place during nf_tables
chain validation, this wasn't possible earlier due to rcu read lock,
but nowadays its not held anymore during set walks.

6) Don't fail conntrack packetdrill test with HZ=100 kernels.

rtc: Add new rtc-macsmc driver for Apple Silicon Macs

Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.

The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

MAINTAINERS: drop unneeded file entry in NVIDIA VRS RTC DRIVER

Commit 9d6d6b06933c ("rtc: nvvrs: add NVIDIA VRS RTC device driver") adds
the section NVIDIA VRS RTC DRIVER in MAINTAINERS, which refers to the
non-existing file include/linux/rtc/rtc-nvidia-vrs10.h

Note, with the changes of v6 to v7 of the patch series adding the driver,
the content of this include file was moved into the driver file, and the
include file was dropped from that patch. It was simply missed to adjust
the section in MAINTAINERS that was newly added with that patch.

Drop the file entry to this non-existing file accordingly now.
