From: David Vrabel <david.vrabel@citrix.com> The high resolution timer code gets notified of step changes to the system time with clock_was_set() or clock_was_set_delayed() calls. If other parts of the kernel require similar notification there is no clear place to hook into. Add a clock_was_set atomic notifier chain (clock_was_set_notifier_list) and call this in place of clock_was_set().

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up

Currently the blacklist is maintained by hand in kprobes.c which is separated from the function definition and is hard to catch up the kernel update. To solve this issue, I've tried to implement new NOKPROBE_SYMBOL() macro for making kprobe blacklist at build time. Since the NOKPROBE_SYMBOL() macros can be placed right after the function is defined, it is easy to maintain. This series
