gentler fair-sleepers feature\n\nAdd back FAIR_SLEEPERS and GENTLE_FAIR_SLEEPERS.\n\nFAIR_SLEEPERS is the old logic: credit sleepers with their sleep time.\n\nGENTLE_FAIR_SLEEPERS dampens this a bit: 50% of their sleep time gets\ncredited.\n\nThe hope here is to still give the benefits of fair-sleepers logic\n(quick wakeups, etc.) while not allow them to have 100% of their\nsleep time as if they were running.\n\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Ingo Molnar

This fixes a bug on s390, where we allow both config options\nHIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE\nhere. We only allow hibernation if no memory hotplug operation was\nperformed, so in fact both features can only be used exclusively, but\nthis way we don\u0027t need 2 differently configured (distribution) kernels.\n\nIf we have an unpopulated ZONE_MOVABLE, we allow hibernation but run\ninto a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation\ncode iterates through all zones, not only the populated zones, in\nseveral places. For example, swsusp_free() does for_each_zone() and\nthen checks for pfn_valid(), which is true even if the zone is not\npopulated, resulting in a BUG_ON() later because the pfn cannot be\nfound in the memory bitmap.\n\nReplacing all occurences of for_each_zone() in hibernation code with\nfor_each_populated_zone() would fix this issue.\n\n[rjw: Rebased on top of linux-next hibernation patches.]\n\nSigned-off-by: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nAcked-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Rafael J.
