Subject: mm/page_table_check: drop all redundant EXPORT_SYMBOL()
Function definitions need not be exported via EXPORT_SYMBOL() mechanism.
In this case these functions just get called only inside their wrappers.
Even __page_table_check_zero() gets called without such an export. Just
drop all these redundant EXPORT_SYMBOL()s.
