Charge movement occurs when processing\nwrites to memory.force_empty, moving tasks to a memcg with\nmemcg.move_charge_at_immigrate\u003d1, or memcg deletion.\n\nAn example showing error after memory.force_empty:\n\n $ cd /sys/fs/cgroup/memory\n $ mkdir x\n $ rm /data/tmp/file\n $ (echo $BASHPID \u003e\u003e x/tasks \u0026\u0026 exec mmap_writer /data/tmp/file 1M) \u0026\n [1] 13600\n $ grep ^mapped x/memory.stat\n mapped_file 1048576\n $ echo 13600 \u003e tasks\n $ echo 1 \u003e x/memory.force_empty\n $ grep ^mapped x/memory.stat\n mapped_file 4503599627370496\n\nmapped_file should end with 0.\n 4503599627370496 \u003d\u003d 0x10,0000,0000,0000 \u003d\u003d 0x100,0000,0000 pages\n 1048576 \u003d\u003d 0x10,0000 \u003d\u003d 0x100 pages\n\nThis issue only affects the source memcg on 64 bit machines; the\ndestination memcg counters are correct. So the rmdir case is not too\nimportant because such counters are soon disappearing with the entire\nmemcg. But the memcg.force_empty and memory.move_charge_at_immigrate\u003d1\ncases are larger problems as the bogus counters are visible for the\n(possibly long) remaining life of the source memcg.\n\nThe problem is due to memcg use of __this_cpu_from(.., -nr_pages), which\nis subtly wrong because it subtracts the unsigned int nr_pages (either\n-1 or -512 for THP) from a signed long percpu counter. When\nnr_pages\u003d-1, -nr_pages\u003d0xffffffff. On 64 bit machines stat-\u003ecount[idx]\nis signed 64 bit. So memcg\u0027s attempt to simply decrement a count (e.g.\nfrom 1 to 0) boils down to:\n\n long count \u003d 1\n unsigned int nr_pages \u003d 1\n count +\u003d -nr_pages /* -nr_pages \u003d\u003d 0xffff,ffff */\n count is now 0x1,0000,0000 instead of 0\n\nThe fix is to subtract the unsigned page count rather than adding its\nnegation. This only works once \"percpu: fix this_cpu_sub() subtrahend\ncasting for unsigneds\" is applied to fix this_cpu_sub().\n\nSigned-off-by: Greg Thelen \u003cgthelen@google.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\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": "bd09d9a35111b6ffc0c7585d3853d0ec7f9f1eb4", "tree": "d2183dd9349217860e07bb12ba9a6b6a3820b7ba", "parents": [ "3017f079efd6af199b0852b5c425364513db460e" ], "author": { "name": "Greg Thelen", "email": "gthelen@google.com", "time": "Wed Oct 30 13:56:20 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Oct 30 14:27:03 2013 -0700" }, "message": "percpu: fix this_cpu_sub() subtrahend casting for unsigneds\n\nthis_cpu_sub() is implemented as negation and addition.\n\nThis patch casts the adjustment to the counter type before negation to\nsign extend the adjustment.

They seem to be mostly IVB machines, including but\napparently not limited to Dell XPS 13, Asus TX300, Asus UX31A, Asus\nUX32VD, Acer Aspire S7. They seem to work in CSM or legacy boot.\n\nThe difference between UEFI and CSM is that the BIOS provides a\ndifferent VBT to the kernel. The UEFI VBT typically specifies 18 bpp and\n1.62 GHz link for eDP, while CSM VBT has 24 bpp and 2.7 GHz link. We end\nup clamping to 18 bpp in UEFI mode, which we can fit in the 1.62 Ghz\nlink, and for reasons yet unknown fail to light up the panel.\n\nDithering from 24 to 18 bpp itself seems to work; if we use 18 bpp with\n2.7 GHz link, the eDP panel lights up. So essentially this is a link\nspeed issue, and *not* a bpp clamping issue.\n\nThe bug raised its head since\ncommit 657445fe8660100ad174600ebfa61536392b7624\nAuthor: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\nDate: Sat May 4 10:09:18 2013 +0200\n\n Revert \"drm/i915: revert eDP bpp clamping code changes\"\n\nwhich started clamping bpp *before* computing the link requirements, and\nthus affecting the required bandwidth. Clamping after the computations\nkept the link at 2.7 GHz.\n\nEven though the BIOS tells us to use 18 bpp through the VBT, it happily\nboots up at 24 bpp and 2.7 GHz itself! Use this information to\nselectively ignore the VBT provided value.\n\nWe can\u0027t ignore the VBT eDP bpp altogether, as there are other laptops\nthat do require the clamping to be used due to EDID reporting higher bpp\nthan the panel can support.\n\nBugzilla: https://bugzilla.kernel.org/show_bug.cgi?id\u003d59841\nBugzilla: https://bugs.freedesktop.org/show_bug.cgi?id\u003d67950\nTested-by: Ulf Winkelvos \u003culf@winkelvos.de\u003e\nTested-by: jkp \u003cjkp@iki.fi\u003e\nCC: stable@vger.kernel.org\nSigned-off-by: Jani Nikula \u003cjani.nikula@intel.com\u003e\nSigned-off-by: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\n" }, { "commit": "7195a50b5c7e00cc3312934fd022c3006b533d12", "tree": "1e15e1fd244325ab88dae65445b9801c3140e03d", "parents": [ "4f56d12ebb28fceac4c6e60c8993fbfc122e1399" ], "author": { "name": "Ville Syrjälä", "email": "ville.syrjala@linux.intel.com", "time": "Tue Sep 24 14:24:05 2013 +0300" }, "committer": { "name": "Daniel Vetter", "email": "daniel.vetter@ffwll.ch", "time": "Mon Oct 28 17:48:24 2013 +0100" }, "message": "drm/i915: Add HSW CRT output readout support\n\nCall intel_ddi_get_config() to get the pipe_bpp settings from\nDDI.\n\nThe sync polarity settings from DDI are irrelevant for CRT\noutput, so override them with data from the ADPA register.\n\nNote: This is already merged in drm-intel-next-queued as\n\ncommit 6801c18c0a43386bb44712cbc028a7e05adb9f0d\nAuthor: Ville Syrjälä \u003cville.syrjala@linux.intel.com\u003e\nDate: Tue Sep 24 14:24:05 2013 +0300\n\n drm/i915: Add HSW CRT output readout support\n\nbut is required for the following edp bpp bugfix.\n\nv2: Extract intel_crt_get_flags()\n\nBugzilla: https://bugs.freedesktop.org/show_bug.cgi?id\u003d69691\nTested-by: Qingshuai Tian \u003cqingshuai.tian@intel.com\u003e\nSigned-off-by: Ville Syrjälä \u003cville.syrjala@linux.intel.com\u003e\nCc: stable@vger.kernel.org\nSigned-off-by: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\n" }, { "commit": "298402a3858e17e6a78acafa1dcd490167dd9f74", "tree": "7696f718a538f94df7a70a9409a27a9f02ac5d2e", "parents": [ "ff18620c2157671a8ee21ebb8e6a3520ea209b1f" ], "author": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Mon Oct 28 14:21:50 2013 +0100" }, "committer": { "name": "Mark Brown", "email": "broonie@linaro.org", "time": "Mon Oct 28 09:33:10 2013 -0700" }, "message": "ASoC: dapm: Return -ENOMEM in snd_soc_dapm_new_dai_widgets()\n\n... instead of NULL dereferences.\n\nSpotted by coverity CID 402004.\n\nSigned-off-by: Takashi Iwai \u003ctiwai@suse.de\u003e\nSigned-off-by: Mark Brown \u003cbroonie@linaro.org\u003e\n" }, { "commit": "ff18620c2157671a8ee21ebb8e6a3520ea209b1f", "tree": "cda116a752e68ba91d82178860fb6edc063f8ba2", "parents": [ "959f58544b7f20c92d5eb43d1232c96c15c01bfb" ], "author": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Mon Oct 28 14:21:49 2013 +0100" }, "committer": { "name": "Mark Brown", "email": "broonie@linaro.org", "time": "Mon Oct 28 09:32:57 2013 -0700" }, "message": "ASoC: dapm: Fix source list debugfs outputs\n\n... due to a copy \u0026 paste error.\n\nSpotted by coverity CID 710923.\n\nSigned-off-by: Takashi Iwai \u003ctiwai@suse.de\u003e\nSigned-off-by: Mark Brown \u003cbroonie@linaro.org\u003e\nCc: stable@vger.kernel.org\n" }, { "commit": "d17cccbea95933a2ab3e260fab128f5128c9371f", "tree": "b3fb0d0e26c741aa14a9bfa6bceb5ec7e740bb62", "parents": [ "959f58544b7f20c92d5eb43d1232c96c15c01bfb", "2fd869f08aec5a8e4cbf01bc3fa345c4e53342d7" ], "author": { "name": "Ingo Molnar", "email": "mingo@kernel.org", "time": "Mon Oct 28 15:56:50 2013 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@kernel.org", "time": "Mon Oct 28 15:56:50 2013 +0100" }, "message": "Merge tag \u0027perf-urgent-for-mingo\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent\n\nPull perf/urgent fixes from Arnaldo Carvalho de Melo:\n\n* Fix up /proc/PID/maps parsing, where perfectly fine mmap entries\n were being trown away when synthesizing PERF_RECORD_MMAP for\n preexisting threads, prevenging symbol resolution to work\n for those threads, broken in the MMAP2 removal.
