[PATCH RFC] ARM: mm: Fix for highmem on machines with more than 14 cores

[Anders Berg]

Hi,

While working of platform support for the LSI AXM5516 SoC (a 16 x A15 device)
we ran into this limitation in fixmap.h where there is not enough room for the
per-cpu pages if NR_CPUS is set to 16.

The following patch avoids the overlap by lowering the base address according to
the values of NR_CPUS and KM_TYPE_NR. Is this the way to handle this?

Thanks,
Anders
