Given that the fixmap area size depends on NR_CPUS and that it can't
possibly cover 4096 CPUs (its size would be beyond 200Mb if I put things
together correctly, whereas the vmalloc area [of which the fixmap area is
a sub-portion] by default is 128MB) I can't see how this new limit ought to
even boot on any system.
Therefore I wonder whether the range shouldn't be restricted for X86_32.
