    warnings, e.g.
    
    mm/page_owner.c: In function '__set_page_owner':
    mm/page_owner.c:71:2: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
    include/linux/page_idle.h: In function 'set_page_young':
    include/linux/page_idle.h:62:3: error: expected ')' before 'return'
    
    This fixes all of them. Please fold into the original patch.
