H A Dhighmem.rst12 High memory (highmem) is used when the size of physical memory approaches or
19 refer to as 'highmem'. There are various architecture dependent constraints on
82 virtual address of the direct mapping. Only real highmem pages are
87 While they are significantly faster than kmap(), for the highmem case they
