mm: change isolate mode from #define to bitwise type
commit 4356f21d09283dc6d39a6f7287a65ddab61e2808 upstream.
Stable note: Not tracked in Bugzilla. This patch makes later patches
easier to apply but has no other impact.
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
