If the offset reaches the last mapped\naddress of the mm then it then it starts over at the first\naddress.\n\nThe per-task nature of the working set sampling functionality in this tree\nallows such constant rate, per task, execution-weight proportional sampling\nof the working set, with an adaptive sampling interval/frequency that\ngoes from once per 100ms up to just once per 8 seconds. The current\nsampling volume is 256 MB per interval.\n\nAs tasks mature and converge their working set, so does the\nsampling rate slow down to just a trickle, 256 MB per 8\nseconds of CPU time executed.\n\nThis, beyond being adaptive, also rate-limits rarely\nexecuting systems and does not over-sample on overloaded\nsystems.\n\n[ In AutoNUMA speak, this patch deals with the effective sampling\n rate of the \u0027hinting page fault\u0027.

The lruvec\npointer is discovered either by mem_cgroup_zone_lruvec() or by\nmem_cgroup_page_lruvec(), and both of those do know the right zone.\n\nSo check and set lruvec-\u003ezone in those; and remove the inadequate\nattempt to set lruvec-\u003ezone from lruvec_init(), which is called before\nNODE_DATA(node) has been allocated in such cases.\n\nAh, there was one exceptionr. For no particularly good reason,\nmem_cgroup_force_empty_list() has its own code for deciding lruvec.\nChange it to use the standard mem_cgroup_zone_lruvec() and\nmem_cgroup_get_lru_size() too. In fact it was already safe against such\nan oops (the lru lists in danger could only be empty), but we\u0027re better\nproofed against future changes this way.\n\nI\u0027ve marked this for stable (3.6) since we introduced the problem in 3.5\n(now closed to stable); but I have no idea if this is the only fix\nneeded to get memory hotadd working with memcg in 3.6, and received no\nanswer when I enquired twice before.\n\nReported-by: Tang Chen \u003ctangchen@cn.fujitsu.com\u003e\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nAcked-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Konstantin Khlebnikov \u003ckhlebnikov@openvz.org\u003e\nCc: Wen Congyang \u003cwency@cn.fujitsu.com\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "18f694271b86ee279e88208550cc49fee206b544", "tree": "3f0f2ed2ab651821af8de877bcc27d087b78b3c7", "parents": [ "9a5a8f19b43430752067ecaee62fc59e11e88fa6" ], "author": { "name": "David Rientjes", "email": "rientjes@google.com", "time": "Fri Nov 16 14:14:52 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 16 14:33:04 2012 -0800" }, "message": "mips, arc: fix build failure\n\nUsing a cross-compiler to fix another issue, the following build error\noccurred for mips defconfig:\n\n arch/mips/fw/arc/misc.c: In function \u0027ArcHalt\u0027:\n arch/mips/fw/arc/misc.c:25:2: error: implicit declaration of function \u0027local_irq_disable\u0027\n\nFix it up by including irqflags.h.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9a5a8f19b43430752067ecaee62fc59e11e88fa6", "tree": "ffa31761b0e208d8be324dc97368caf4bea87fd8", "parents": [ "1756954c61cb5c97c618ccb366482b9c1f891d6d" ], "author": { "name": "Michal Hocko", "email": "mhocko@suse.cz", "time": "Fri Nov 16 14:14:49 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Nov 16 14:33:04 2012 -0800" }, "message": "memcg: oom: fix totalpages calculation for memory.swappiness\u003d\u003d0\n\noom_badness() takes a totalpages argument which says how many pages are\navailable and it uses it as a base for the score calculation.

This check has been added before the WORD_SWAP\nregister is programmed, so we need to check for swapped register\nvalue as well.\n\nBit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning\n\u003csteve@shawell.net\u003e checked with SMSC and wrote:\n\n The chip architects have concluded we should be reading PMT_CTRL\n until we see any of bits 0, 8, 16 or 24 set. Then we should read\n BYTE_TEST to check the byte order is correct (as we already do).\n\n The rationale behind this is that some of the chip variants have\n word order swapping features too, so the READY bit could actually\n be in any of the 4 possible locations. The architects have confirmed\n that if any of these 4 positions is set the chip is ready. The other\n 3 locations will either never be set or can only go high after READY\n does (so also indicate the device is ready).\n\nThis change will check for the READY bit at the 16th position. We do\nnot check the other two cases (bit 8 and 24) since the driver does not\nsupport byte-swapped register read/write.\n\nSigned-off-by: Kamlakant Patel \u003ckamlakant.patel@broadcom.com\u003e\nSigned-off-by: David S.
