Hello David,

I have identified this next serie of prerequisites for PowerNV that should 
not need too much discussion. When would be the right time to send them ? 

        [PATCH 01/77] ppc: Remove MMU_MODEn_SUFFIX definitions
        [PATCH 02/77] ppc: Use split I/D mmu modes to avoid flushes on
        [PATCH 03/77] ppc: Do some batching of TCG tlb flushes
        [PATCH 07/77] ppc: Add a bunch of hypervisor SPRs to Book3s
        [PATCH 09/77] ppc: Fix hreg_store_msr() so that non-HV mode cannot
        [PATCH 10/77] ppc: Fix rfi/rfid/hrfi/... emulation
        [PATCH 12/77] ppc: Better figure out if processor has HV mode
        [PATCH 13/77] ppc: tlbie, tlbia and tlbisync are HV only
        [PATCH 14/77] ppc: Change 'invalid' bit mask of tlbiel and tlbie
        [PATCH 15/77] ppc: Fix sign extension issue in mtmsr(d) emulation
        [PATCH 16/77] ppc: Get out of emulation on SMT "OR" ops
        [PATCH 17/77] ppc: Add PPC_64H instruction flag to POWER7 and POWER8


The exception model changes are rather invasive but they are complex so 
I will keep them for later and I would like to try getting the xics changes 
out of the way first. They are a pain to maintain out of the mainline tree. 
Could we follow on with xics then ? 

Thanks,

C.
