CPUs 0-2 were already marked offline and\nwe were in the process of offlining CPU 3. After marking\nthe CPU inactive and offline in cpu_disable, but before the\ncpu was completely idle (cpu_die), we ended up in __make_request\non CPU 3. There we looked at the topology map to see which CPU\nto complete the I/O on and found no CPUs in the cpu_sibling_map.\nThis resulted in the block layer setting the completion cpu\nto be NR_CPUS, which then caused an oops when we tried to\ncomplete the I/O.\n\nFix this by sanity checking the value we return from blk_cpu_to_group\nto be a valid cpu value.\n\nSigned-off-by: Brian King \u003cbrking@linux.vnet.ibm.com\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n" }, { "commit": "5431427b1a5acbae0b3dffd91f6ba96aee141f43", "tree": "ddd1bdb5a2f634a953fab68a6318d86c46b088cd", "parents": [ "a7a13d0676335a7dc9dd72264cca02606e43aaba", "122661b67899980f1372812d907e73ebcfb3d037" ], "author": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Fri Sep 10 08:27:00 2010 +0200" }, "committer": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Fri Sep 10 08:27:00 2010 +0200" }, "message": "Merge branch \u0027fix/hda\u0027 into for-linus\n" }, { "commit": "9efdda310cb26bdc28429cb831c3ec5fa270feb7", "tree": "7d544a56502b8b943a1cba667805bde0200063da", "parents": [ "e1d4e08d1fa302f877d9a26d8ce056734b46ca14", "df09162550fbb53354f0c88e85b5d0e6129ee9cc" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Sep 10 08:05:34 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Sep 10 08:05:34 2010 +0200" }, "message": "Merge branch \u0027tip/perf/urgent\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace into perf/urgent\n" }, { "commit": "e1d4e08d1fa302f877d9a26d8ce056734b46ca14", "tree": "874a31dbf32dd9c0930a0a3971f7e5b209b6e6f9", "parents": [ "5e11637e2c929e34dcc0fbbfb48bdb638937701a", "85e00b55517a5696282b80836655e6b6f5702df0" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Sep 10 07:34:14 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Sep 10 07:34:14 2010 +0200" }, "message": "Merge branch \u0027perf/urgent\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6 into perf/urgent\n" }, { "commit": "053d8f6622701f849fda2ca2c9ae596c13599ba9", "tree": "e5dd90cca3a69bc993b5aa860a9eeb8c9178450a", "parents": [ "c9cedbba0fc591e1c0587f838932ca3f3c6fec57", "615cc2211c17ed05a2a5d94abdac6c340a8ea508" ], "author": { "name": "David S.

When under significant pressure on systems with large numbers of\nCPUs, it\u0027s possible for processes to make progress even though they should\nhave been stalled. This is particularly problematic if a number of the\nprocesses are using GFP_ATOMIC as the min watermark can be accidentally\nbreached and in extreme cases, the system can livelock.\n\nThis patch updates the counters after the pages have been added to the\nlist. This makes the allocator more cautious with respect to preserving\nthe watermarks and mitigates livelock possibilities.\n\n[akpm@linux-foundation.org: avoid modifying incoming args]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nReviewed-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nReviewed-by: Christoph Lameter \u003ccl@linux.com\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nAcked-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "5ee28a447625b9fe64fbf7cff026561084fc5f16", "tree": "345e3afc3ce70af1892ce1c0ec953b68ef8a1770", "parents": [ "3ab04d5cf9736b7a4e9dfcf28285d8663b01aa0e" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Thu Sep 09 16:38:14 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 09 18:57:25 2010 -0700" }, "message": "vmstat: update zone stat threshold when onlining a cpu\n\nrefresh_zone_stat_thresholds() calculates parameter based on the number of\nonline cpus.

So we\nhas been two too_many_isolated.\n\nWhile compaction can isolate pages in both active and inactive, current\nimplementation of too_many_isolated only considers inactive. It made\nIram\u0027s problem.\n\nThis patch handles active and inactive fairly. That\u0027s because we can\u0027t\nexpect where from and how many compaction would isolated pages.\n\nThis patch changes (nr_isolated \u003e nr_inactive) with\nnr_isolated \u003e (nr_active + nr_inactive) / 2.\n\nSigned-off-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nReported-by: Iram Shahzad \u003ciram.shahzad@jp.fujitsu.com\u003e\nAcked-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: \u003cstable@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": "1c24de60e50fb19b94d94225458da17c720f0729", "tree": "a225907a1b341f629037805f086add137e176f4a", "parents": [ "94131e174fedd9f3f9bb148cee4be12f2d46d68e" ], "author": { "name": "Jerome Marchand", "email": "jmarchan@redhat.com", "time": "Thu Sep 09 16:37:59 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 09 18:57:24 2010 -0700" }, "message": "kernel/groups.c: fix integer overflow in groups_search\n\ngid_t is a unsigned int.
