    Subjectabout kmap_high function
        I found that the kmap_high function didn't call __flush_tlb_one()
    when it mapped a highmem page sucessfully, and I think it maybe
    cause the problem that TLB may store obslete page table entries, but
    the kmap_atomic() function do call the __flush_tlb_one(), someone tell
    me what's the differenc between the kmap_atomic and kmap_high except
    that kmap_atomic can be used in IRQ contexts. I appreciate in advance.
