    arch/kmap_atomic: consolidate duplicate code · 78b6d91e
    Ira Weiny authored
    Every arch has the same code to ensure atomic operations and a check for
    !HIGHMEM page.
    
    Remove the duplicate code by defining a core kmap_atomic() which only
    calls the arch specific kmap_atomic_high() when the page is high memory.
