    mm: change isolate mode from #define to bitwise type · 4356f21d
    Minchan Kim 提交于
    Change ISOLATE_XXX macro with bitwise isolate_mode_t type.  Normally,
    macro isn't recommended as it's type-unsafe and making debugging harder as
    symbol cannot be passed throught to the debugger.
    
    Quote from Johannes
    " Hmm, it would probably be cleaner to fully convert the isolation mode
    into independent flags.  INACTIVE, ACTIVE, BOTH is currently a
    tri-state among flags, which is a bit ugly."
    
    This patch moves isolate mode from swap.h to mmzone.h by memcontrol.h
