37 | * compile time, but to set the physical address only | ||
38 | * in the boot process. We allocate these special addresses | ||
39 | * from the end of virtual memory (0xfffff000) backwards. | ||
40 | * Also this lets us do fail-safe vmalloc(), we | ||
41 | * can guarantee that these special addresses and | ||
42 | * vmalloc()-ed addresses never overlap. | ||
43 | * | ||
44 | * these 'compile-time allocated' memory buffers are | ||
45 | * fixed-size 4k pages. (or larger if used with an increment | ||
46 | * highger than 1) use fixmap_set(idx,phys) to associate | ||
47 | * physical memory with fixmap indices. | ||

49 | * TLB entries of such buffers will not be flushed across | ||
50 | * task switches. | ||
