BTW-- what kernel version introduced this change for ppc64?
4-level pagetable went into 2.6.14 for ppc64.
Yuck. That reminds me that "pud_clear_bad()" is not a good
choice for detecting new layout (its a generic routine - not
ppc64 specific and is in 2.6.11 onwards).
Funny thing is, I am not sure original crash is working
on pre-2.6.14 kernel either. I see PTE_SHIFT changed from
16 to 17 in 2.6.10. I guess crash is broken from 2.6.10
onwards for ppc64.
2.6.10 onwards:
#define PTE_SHIFT (17)
< 2.6.10: (which crash understands)
#define PTE_SHIFT (16)
