Subject: [GIT PULL] x86/cache changes for v5.6

Linus,

Please pull the latest x86-cache-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cache-for-linus

   # HEAD: e79f15a4598c1f3f3f7f3319ca308c63c91fdaf2 x86/resctrl: Add task resctrl information display

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.
