[PATCH v3 4/8] pdx: allow per-arch optimization of PDX conversion helpers

2025-07-24 Thread Roger Pau Monne
There are four performance critical PDX conversion helpers that do the PFN to/from PDX and the physical addresses to/from directmap offsets translations. In the absence of an active PDX compression, those functions would still do the calculations needed, just to return the same input value as no t
