Merge tag 'x86_cache_for_v6.3_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 resource control updates from Borislav Petkov:
- Add support for a new AMD feature called slow memory bandwidth
allocation. Its goal is to control resource allocation in external
slow memory which is connected to the machine like for example
through CXL devices, accelerators etc
