21 * Here we define all the compile-time 'special' virtual
22 * addresses. The point is to have a constant address at
23 * compile time, but to set the physical address only
24 * in the boot process.
25 *
26 * These 'compile-time allocated' memory buffers are
27 * fixed-size 4k pages (or larger if used with an increment
28 * higher than 1). Use set_fixmap(idx,phys) to associate
29 * physical memory with fixmap indices.
30 *
31 * TLB entries of such buffers will not be flushed across
32 * task switches.
