Vlastimil Babka 3dfbb555c9 mm, vmscan: remove ISOLATE_UNMAPPED
This isolate_mode_t flag is effectively unused since 89f6c88a6ab4 ("mm:
__isolate_lru_page_prepare() in isolate_migratepages_block()") as
sc->may_unmap is now checked directly (and only node_reclaim has a mode
that sets it to 0).  The last remaining place is mm_vmscan_lru_isolate
tracepoint for the isolate_mode parameter.  That one was mainly used to
indicate the active/inactive mode, which the trace-vmscan-postprocess.pl
script consumed, but that got silently broken.  After fixing the script by
the previous patch, it does not need the isolate_mode anymore.  So just
remove the parameter and with that the whole ISOLATE_UNMAPPED flag.
