This didn't become a serious problem until Red Hat made the
unfortunate (though not realized at the time) mistake of switching to
64k pages for ARM and POWER. We got that change in Fedora for POWER
but not ARM. It has led to all kinds of unfortunate problems that are
gradually being worked on and fixed upstream.
There have been arches in the kernel that didn't support a 4K page size. FRV,
for example, only supported 16K pages. I don't know if any of the
"non-regular" arches still in the kernel have similar constraints.
