- * highmem.h: virtual kernel memory mappings for high memory
- *
- * Used in CONFIG_HIGHMEM systems for memory pages which
- * are not addressable by direct kernel virtual addresses.
- *
- * Copyright (C) 1999 Gerhard Wichert, Siemens AG
- * Gerhard.Wichert@pdb.siemens.de
- *
- *
- * Redesigned the x86 32-bit VM architecture to deal with
- * up to 16 Terabyte physical memory. With current x86 CPUs
- * we now support up to 64 Gigabytes physical RAM.
