One fix for the interrupt rework we did last release which broke KVM-PR.
Three commits fixing some fallout from the READ_ONCE() changes interacting badly
with our 8xx 16K pages support, which uses a pte_t that is a structure of 4
actual PTEs.
A cleanup of the 8xx pte_update() to use the newly added pmd_off().
A fix for a crash when handling an oops if CONFIG_DEBUG_VIRTUAL is enabled.
A minor fix for the SPU syscall generation.
Thanks to:
Aneesh Kumar K.V, Christian Zigotzky, Christophe Leroy, Mike Rapoport,
Nicholas Piggin.
