    powerpc/mm: Dump hash table · 1515ab93
    Rashmica Gupta authored
    Useful to be able to dump the kernel hash page table to check
    which pages are hashed along with their sizes and other details.
    
    Add a debugfs file to check the hash page table. If radix is enabled
    (and so there is no hash page table) then this file doesn't exist. To
    use this the PPC_PTDUMP config option must be selected.
