       pte = pte_swp_clear_soft_dirty(pte);
    
    We support soft dirty tracking only with book3s 64 for now.
    So change the Kconfig dependency accordingly. Also CHECKPOINT_RESTORE
    feature is not really dependent on SOFT_DIRTY. We track the dependency
    between MEM_SOFT_DIRTY and ARCH_SOFT_DIRTY through headers
    
    Fixes: 7207f436 ("powerpc/mm: Add page soft dirty tracking")
