This patch series fixes two issues regarding Platform QoS (resctrl) support on Hygon CPUs.
The first patch adds the missing initialization sequence required for proper resctrl functionality. The second patch corrects the bit-width configuration for the Memory Bandwidth Monitoring (MBM) counter.
Changelog: v3: - Remove the "Fixes: 923f3a2b48bd..." tag in two patches because this commit itself doesn't have an issue (Fenghua).
v2: - Add "Reviewed-by:" tag in patch 1/2: "Reviewed-by: Reinette Chatre <reinette.chatre@intel.com>" - Add "Reviewed-by:" tags in patch 2/2: "Reviewed-by: Tony Luck <tony.luck@intel.com>" "Reviewed-by: Reinette Chatre <reinette.chatre@intel.com>" - Move the "Cc: stable@vger.kernel.org" tag to be after the author's SoB to comply with tip tree rules (Reinette)
