   # HEAD: 7950de14ff5fd8da355d872b887ee8b7b5a1f327 perf/x86/intel: Add Panther Lake support

Miscellaneous fixes and a hardware-enabling change:

 - Fix Intel uncore PMU IIO free running counters on
   SPR, ICX and SNR systems.

 - Fix Intel PEBS buffer overflow handling

 - Fix skid in Intel PEBS sampling of user-space
   general purpose registers

 - Enable Panther Lake PMU support - similar to Lunar Lake.

 Thanks,

	Ingo
