sparse complains about every MODULE_PARM used in a module: warning: symbol

The fix is to split declaration and initialization. While MODULE_PARM is
obsolete, it's not something sparse should report.

Final step in pushing down common core's page_table_lock. follow_page no
longer wants caller to hold page_table_lock, uses pte_offset_map_lock itself;
and so no page_table_lock is taken in get_user_pages itself.
But get_user_pages (and get_futex_key) do then need follow_page to pin the
page for them:... | ```diff

Small fix to the PageReserved patch: the mips ZERO_PAGE(address) depends on
