    powerpc/mm/hash: Add support for Power9 Hash · 50de596d
    Aneesh Kumar K.V authored
    PowerISA 3.0 adds a parition table indexed by LPID. Parition table
    allows us to specify the MMU model that will be used for guest and host
    translation.
    
    This patch adds support with SLB based hash model (UPRT = 0). What is
    required with this model is to support the new hash page table entry
    format and also setup partition table such that we use hash table for
    address translation.
    
    We don't have segment table support yet.
    
    In order to make sure we don't load KVM module on Power9 (since we don't
    have kvm support yet) this patch also disables KVM on Power9.
