Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 resource control updates from Ingo Molnar:
"The main change in this tree is the extension of the resctrl procfs
ABI with a new file that helps tooling to navigate from tasks back to
resctrl groups: /proc/{pid}/cpu_resctrl_groups.
Also fix static key usage for certain feature combinations and
simplify the task exit resctrl case"
* 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/resctrl: Add task resctrl information display
x86/resctrl: Check monitoring static key in the MBM overflow handler
x86/resctrl: Do not reconfigure exiting tasks
