Pull x86 resource control updates from Borislav Petkov:
- Add a tracepoint to read out LLC occupancy of resource monitor IDs
with the goal of freeing them sooner rather than later
- Other code improvements and cleanups
* tag 'x86_cache_for_v6.10_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
