kernel/time/posix-stubs.c: remove duplicated include (2023-06-23 17:04:05 -0700)
----------------------------------------------------------------
- Arnd Bergmann has fixed a bunch of -Wmissing-prototypes in
top-level directories.
- Douglas Anderson has added a new "buddy" mode to the hardlockup
detector. It permits the detector to work on architectures which
cannot provide the required interrupts, by having CPUs periodically
perform checks on other CPUs.
- Zhen Lei has enhanced kexec's ability to support two crash regions.
- Petr Mladek has done a lot of cleanup on the hard lockup detector's
Kconfig entries.
- And the usual bunch of singleton patches in various places.
