Pull non-MM updates from Andrew Morton:

- The series "powerpc/crash: use generic crashkernel reservation" from
Sourabh Jain changes powerpc's kexec code to use more of the generic
layers.

- The series "get_maintainer: report subsystem status separately" from
Vlastimil Babka makes some long-requested improvements to the
get_maintainer output.

- The series "ucount: Simplify refcounting with rcuref_t" from
Sebastian Siewior cleans up and optimizing the refcounting in the
ucount code.

- The series "reboot: support runtime configuration of emergency
hw_protection action" from Ahmad Fatoum improves the ability for a
driver to perform an emergency system shutdown or reboot.

- The series "Converge on using secs_to_jiffies() part two" from Easwar
Hariharan performs further migrations from msecs_to_jiffies() to
secs_to_jiffies().

- The series "lib/interval_tree: add some test cases and cleanup" from
Wei Yang permits more userspace testing of kernel library code, adds
some more tests and performs some cleanups.

- The series "hung_task: Dump the blocking task stacktrace" from Masami
Hiramatsu arranges for the hung_task detector to dump the stack of
the blocking task and not just that of the blocked task.

- The series "resource: Split and use DEFINE_RES*() macros" from Andy
Shevchenko provides some cleanups to the resource definition macros.

- Plus the usual shower of singleton patches - please see the
individual changelogs for details.

scripts: add script to extract built-in firmware blobs

There is currently no tool to extract a firmware blob that is built-in
on vmlinux to the best of my knowledge. So if we have a kernel image
containing the blobs, and we want to rebuild the kernel with some debug
patches for example (and given that the image also has IKCONFIG=y), we
currently can't do that for the same versions for all the firmware
blobs, _unless_ we have exact commits of linux-firmware for the
specific versions for each firmware included.

Through the options CONFIG_EXTRA_FIRMWARE{_DIR} one is able to build a
kernel including firmware blobs in a built-in fashion. This is usually
the case of built-in drivers that require some blobs in order to work
properly, for example, like in non-initrd based systems.

Add hereby a script to extract these blobs from a non-stripped vmlinux,
similar to the idea of "extract-ikconfig". The firmware loader interface
saves such built-in blobs as rodata entries, having a field for the FW
name as "_fw_<module_name>_<firmware_name>_bin"; the tool extracts files
named "<module_name>_<firmware_name>" for each rodata firmware entry
detected. It makes use of awk, bash, dd and readelf, pretty standard
tooling for Linux development.

With this tool, we can blindly extract the FWs and easily re-add them
in the new debug kernel build, allowing a more deterministic testing
without the burden of "hunting down" the proper version of each
firmware binary.
