The generic allocation code may sometimes decide to assign a prefetchable 64-bit BAR to the M32 window. In fact it may also decide to allocate a 64-bit non-prefetchable BAR to the M64 one ! So using the resource flags as a test to decide which window was used for PE allocation is just wrong and leads to insane PE numbers. Instead, compare the addresses to figure it out.

Applied to powerpc fixes, thanks. https://git.kernel.org/powerpc/c/5958d19a143eb229e9ece20bd4 cheers
