    Subject[PATCH v2 0/4] huge vmalloc mappings
    Date
    We can get a significant win with larger mappings for some of the big
    global hashes.

    Since RFC, relevant architectures have added p?d_leaf accessors so no
    real arch changes required, and I changed it not to allocate huge
    mappings for modules and a bunch of other fixes.

    Nicholas Piggin (4):
    mm/vmalloc: fix vmalloc_to_page for huge vmap mappings
    mm: Move ioremap page table mapping function to mm/
    mm: HUGE_VMAP arch query functions cleanup
    mm/vmalloc: Hugepage vmalloc mappings
