I did not try to # reproduce on powerpc, but looking at the code, the same should apply to # powerpc/cmm ever since it started using the balloon compaction # infrastructure (luckily just recently). # # In case we have to migrate a ballon page to a newpage of another zone, the # managed page count of both zones is wrong. Paired with memory offlining # (which will adjust the managed page count), we can trigger kernel crashes # and all kinds of different symptoms. # # Fix it by properly adjusting the managed page count when migrating if # the zone changed. # # We'll temporarily modify the totalram page count. If this ever becomes a # problem, we can fine tune by providing helpers that don't touch # the totalram pages (e.g., adjust_zone_managed_page_count()). # # Fixes: fe030c9b85e6 ("powerpc/pseries/cmm: Implement balloon compaction") #
