Looks like the fix for 6xx/hash use of SPRN_SPRG_PGDIR is not there.

Patch at https://patchwork.ozlabs.org/patch/1053385/
(Or at https://patchwork.ozlabs.org/patch/1054213/ with better commit text)

Without that patch, 6xx with hash table silently loop forever in
pagefault handler while trying to start init, as reported from
linux-next by Guenter Roeck (see
https://patchwork.ozlabs.org/patch/1046041/)

Thanks
Christophe
