Hi Dave,

How have you tested this patch (and the whole series for that matter)?
I replaced the second patch with this one and did a build test. Till v16, I had tested the whole series (build + run) on both a POWER8 system (with 4K and 64K page sizes) and a Skylake SP system but for x86_64 only. Following that, I could only do a build test locally on my laptop for i386 and x86_64 on my laptop as I did not have access to the Skylake system anymore.
This is how I tested the build process:
