#     powerpc/book3s64/hash: Use secondary hash for bolted mapping if the primary is full
#     
#     With bolted hash page table entry, kernel currently only use primary hash group
#     when inserting the hash page table entry. In the rare case where kernel find all the
#     8 primary hash slot occupied by bolted entries, this can result in hash page
#     table insert failure for bolted entries. Avoid this by using the secondary hash
#     group.
#     
#     This is different from what kernel does for the non-bolted mapping. With
#     non-bolted entries kernel will try secondary before removing an existing entry
#     from hash page table group. With bolted prefer primary hash group and hence
#     try to insert the page table entry by removing a slot from primary before trying
#     the secondary hash group.
