v4:	* No changes, only rebased on top of v6.10-rc4

v3:
	* Replaced wp_cfg in arm_cmn_hw_event with wp_idx that keeps
	  track, whether the event uses 0 or 1 index for the given direction
	* Cleaned and simplified allocation/claiming of wp config
	* arm_cmn_val_add_event() can't and won't fail anymore
	* Separated wp_combine from wp[] in event validation phase
	* use memset()/sizeof() when clearing an event
	* Still kept wp config allocator in separate functions - at least
	  for now
	* https://lore.kernel.org/all/20240329013215.169345-1-ilkka@os.amperecomputing.com/

v2:
        * Wp config registers are allocated on node basis, instead
	  of using the same one globally
	* Use bitmap in the event structure to keep track on the
	  wp config registers assigned to the specific event.
	* The bitmap tracks only either UP (wp conf 0&1) or DOWN
	  (wp conf 2&3) registers.
	* Dropped the second patch
	  ("The patch set v2 is now in the internal mailing list")
	  as perf/sysfs doesn't really support items with the same
	  name even if visibility would handle them.
	* Addressed a bunch of other comments by the author
	* https://lore.kernel.org/all/20240307230929.6233-2-ilkka@os.amperecomputing.com/
