[Bug 28813] [GM45] broken swizzling in swap-in/out paths/L-shaped memory swizzling

--- Comment #40 from Chris Wilson <chris at chris-wilson.co.uk> ---
That's good to know. The last remaining detail is a way to detect the L shape
memory configurations. There should be enough info in the CSPEC that the memory
has different swizzle regions (even if not enough info to work out the swizzle)
- as we really only want to enable this page pinning as a means of last resort.
