    [SPARC64]: Fix two kernel linear mapping setup bugs. · 8f361453

    This was caught and identified by Greg Onufer.
    
    Since we setup the 256M/4M bitmap table after taking over the trap
    table, it's possible for some 4M mapping to get loaded in the TLB
    beforhand which later will be 256M mappings.
    
    This can cause illegal TLB multiple-match conditions.  Fix this by
    setting up the bitmap before we take over the trap table.
    
    Next, __flush_tlb_all() was not doing anything on hypervisor
    platforms.  Fix by adding sun4v_mmu_demap_all() and calling it.
