10 | * - flush_tlb() flushes the current mm struct TLBs XXX Exists? | |
11 | * - flush_tlb_all() flushes all processes TLBs | |
12 | * - flush_tlb_mm(mm) flushes the specified mm context TLB's | |
13 | * - flush_tlb_page(vma, vmaddr) flushes one page | |
14 | * - flush_tlb_range(vma, start, end) flushes a range of pages | |
15 | * - flush_tlb_kernel_range(start, end) flushes a range of kernel pages | |
