196 Linux can use the full amount of RAM in the system by
197 default. However, the default MMUv2 setup only maps the
198 lowermost 128 MB of memory linearly to the areas starting
199 at 0xd0000000 (cached) and 0xd8000000 (uncached).
200 When there are more than 128 MB memory in the system not
201 all of it can be "permanently mapped" by the kernel.
202 The physical memory that's not permanently mapped is called
203 "high memory".

206 machine with more than 128 MB total physical RAM, answer
