I think this is irrelevant since we have defconfig for this.  You
apparent request doesn't match the code below.

This shows you're using a buggy compiler.  PTE_OFFSET_SIZE is generated
as part of the build process, so you need a correct compiler.

This doesn't require 64 bit: PA8xxx processors can operate happily in 3=
2
bit mode it does make the question appear, since PA7xxx are 32 bit only=
