-   The software page tables for address space 'mm' for virtual

-   Some platforms cache the lowest level of the software page tables
-   in a linear virtually mapped array, to make TLB miss processing
-   more efficient.  On such platforms, since the TLB is caching the
-   software page table structure, it needs to be flushed when parts
-   of the software page table tree are unlinked/freed.
-
-   Sparc64 is one example of a platform which does this.
-
-   Usually, when munmap()'ing an area of user virtual address
-   space, the kernel leaves the page table parts around and just
-   marks the individual pte's as invalid.  However, if very large
-   portions of the address space are unmapped, the kernel frees up
-   those portions of the software page tables to prevent potential
-   excessive kernel memory usage caused by erratic mmap/mmunmap
-   sequences.  It is at these times that flush_tlb_pgtables will
-   be invoked.
