Could you elaborate a bit on how it broke things?
So originally 0-day build found that commit a10a1701 (mm, x86: add
support for PUD-sized transparent hugepages) is breaking 32bit x86 UP
config because native_pud_clear() was missing to satisfy
arch/x86/include/asm/pgtable.h. I added a dummy function to satisfy that
with commit e4decc90 (mm,x86: native_pud_clear missing on i386 build).
However in the process of doing that, I broke the 32bit x86 SMP config
that was working before.

Which tree is that in, btw?
