Other messages are occasionally printed between these two, for example:
[203104.106534] Restarting tasks ...
[203104.106559] mei_hdcp 0000:00:16.0-b638ab7e-94e2-4ea2-a552-d1c54b627f04: bound 0000:00:02.0 (ops i915_hdcp_ops [i915])
[203104.112354] done.
This seems to be a timing issue, seen in two of the eleven
hibernation exits in my current `dmesg` output.
When printed on its own, the "done" message has the default log level.
This makes the output of `dmesg --level=warn` quite misleading.
Add enough context for the "done" messages to make sense on their own,
and use the same log level for all messages.
Change the messages to "<event>..." / "Done <event>.", unlike a449dfbfc089
which uses "<event>..." / "<event> completed.". Front-loading the unique
part of the message makes it easier to scan the log, and reduces ambiguity
for users who aren't confident in their English comprehension.

The printf format checking in the compiler uses the intmax types from
the compiler, not libc. This can lead to compiler errors.
Instead use the types already provided by the compiler.
Example issue with clang 19 for arm64:

In nolibc intmax_t and uintmax_t are always the same as
(unsigned) long long/uint64_t as 128bit numbers are not supported.
Even libcs that do support 128bit numbers often fix intmax_t to 64bit
as it is used in ABIs and any change would break those.

Various new families and my recent work on rtnetlink missed
adding dependencies on C headers. If the system headers are
up to date or don't include a given header at all this doesn't
make a difference. But if the system headers are in place but
stale - compilation will break.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Initialize hash variables in ftrace subops logic
The fix that simplified the ftrace subops logic opened a path where
some variables could be used without being initialized, and done
subtly where the compiler did not catch it. Initialize those
variables to the EMPTY_HASH, which is the default hash.
- Reinitialize the hash pointers after they are freed
Some of the hash pointers in the subop logic were freed but may still
be referenced later. To prevent use-after-free bugs, initialize them
back to the EMPTY_HASH.
- Free the ftrace hashes when they are replaced
The fix that simplified the subops logic updated some hash pointers,
but left the original hash that they were pointing to where they are
no longer used. This caused a memory leak. Free the hashes that are
pointed to by the pointers when they are replaced.
- Fix size initialization of ftrace direct function hash
The ftrace direct function hash used by BPF initialized the hash size
incorrectly. It checked the size of items to a hard coded 32, which
made the hash bit size of 5. The hash size is supposed to be limited
by the bit size of the hash, as the bitmask is allowed to be greater
than 5. Rework the size check to first pass the number of elements to
fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating
the hash.
- Fix format output of ftrace_graph_ent_entry event
The field depth of the ftrace_graph_ent_entry event is of size 4 but
the output showed it as unsigned long and use "%lu". Change it to
unsigned int and use "%u" in the print format that is displayed to
user space.
- Fix the trace event filter on strings
Events can be filtered on numbers or string values. The return value
checked from strncpy_from_kernel_nofault() and
strncpy_from_user_nofault() was used to determine if reading the
strings would fault or not. It would return fault if the value was
non zero, which is basically meant that it was always considering the
read as a fault.
- Add selftest to test trace event string filtering
In order to catch the breakage of the string filtering, add a self
test to make sure that it continues to work.

Testing revealed the following error message for a CXL memdev that has
Feature support:
[ 56.690430] cxl mem0: Resources present before probing
Attach the allocation of cxl_fwctl to the parent device of cxl_memdev.
devm_add_* calls for cxl_memdev should not happen before the memdev
probe function or outside the scope of the memdev driver.
cxl_test missed this bug because cxl_test always arranges for the
cxl_mem driver to be loaded before cxl_mock_mem runs. So the driver core
always finds the devres list idle in that case.

Running the following commands was broken:
# cd /sys/kernel/tracing
# echo "filename.ustring ~ \"/proc*\"" > events/syscalls/sys_enter_openat/filter
# echo 1 > events/syscalls/sys_enter_openat/enable
# ls /proc/$$/maps
# cat trace
And would produce nothing when it should have produced something like:
ls-1192 [007] ..... 8169.828333: sys_openat(dfd: ffffffffffffff9c, filename: 7efc18359904, flags: 80000, mode: 0)
Add a test to check this case so that it will be caught if it breaks
again.
