mm: do not export ioremap_page_range symbol for external module
Recently, I've found cases in which ioremap_page_range was used
incorrectly, in external modules, leading to crashes. This can be
partly attributed to the fact that ioremap_page_range is lower-level,
with fewer protections, as compared to the other functions that an
external module would typically call. Those include:
ioremap_cache
ioremap_nocache
ioremap_prot
ioremap_uc
ioremap_wc
ioremap_wt
...each of which wraps __ioremap_caller, which in turn provides a safer
way to achieve the mapping.
Therefore, stop EXPORT-ing ioremap_page_range.
