The test is broken w.r.t page table update rules and results in kernel
crash as below. Disable the support untill we get the tests updated.

You say you remove support for ppc64 but you are removing it for both
PPC64 and PPC32. Should you replace the line by:
select ARCH_HAS_DEBUG_VM_PGTABLE if PPC32

What about Documentation/features/debug/debug-vm-pgtable/arch-support.txt ?

Does it work on PPC32 with DEBUG_VM enabled? I was expecting it will be
broken there too.

I am hoping we can enable the config once we resolve the test issues.
may be in next merge window.

I was wondering. I have just started a build to test that on my 8xx.
I'll tell you before noon (Paris).

There are warnings but it boots OK. So up to you, but if you deactivate
it for both PPC32 and PPC64, say so in the subject like.
