To avoid synchronization\noverhead, counter deltas are maintained on a per-cpu basis and drained\nboth periodically and when the delta is above a threshold. On large CPU\nsystems, the difference between the estimated and real value of\nNR_FREE_PAGES can be very high. If NR_FREE_PAGES is much higher than\nnumber of real free page in buddy, the VM can allocate pages below min\nwatermark, at worst reducing the real number of pages to zero. Even if\nthe OOM killer kills some victim for freeing memory, it may not free\nmemory if the exit path requires a new page resulting in livelock.\n\nThis patch introduces a zone_page_state_snapshot() function (courtesy of\nChristoph) that takes a slightly more accurate view of an arbitrary vmstat\ncounter. It is used to read NR_FREE_PAGES while kswapd is awake to avoid\nthe watermark being accidentally broken.

To work correctly, it should be two byte writes,\n not a single word write. As it stands, it does nothing.\n\n- Some devices with sx150x expanders installed have their NRESET pins\n ganged on the same line, so resetting one causes the others to reset -\n not a nice thing to do arbitrarily!\n\n- The probe, usually taking place at boot, implies a recent hard-reset,\n so a software reset at this point is just a waste of energy anyway.\n\nTherefore, make it optional, defaulting to off, as this will match the\ncommon case of probing at powerup and also matches the current broken\nno-op behavior.\n\nSigned-off-by: Gregory Bean \u003cgbean@codeaurora.org\u003e\nReviewed-by: Jean Delvare \u003ckhali@linux-fr.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4969c1192d15afa3389e7ae3302096ff684ba655", "tree": "abe560c8f293191be65488c49f4db3f3a626e63c", "parents": [ "7c5367f205f7d53659fb19b9fdf65b7bc1a592c6" ], "author": { "name": "Andrea Arcangeli", "email": "aarcange@redhat.com", "time": "Thu Sep 09 16:37:52 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 09 18:57:24 2010 -0700" }, "message": "mm: fix swapin race condition\n\nThe pte_same check is reliable only if the swap entry remains pinned (by\nthe page lock on swapcache).

Then,\nacpi_pci_osc_control_set() will run _OSC queries in a loop until\nthe mask of _OSC control bits returned by the BIOS is equal to the\nmask passed to it. Also, before running the _OSC request\nacpi_pci_osc_control_set() will check if the caller\u0027s required\ncontrol bits are present in the final mask.\n\nUsing this mechanism we will be able to avoid situations in which the\nBIOS doesn\u0027t grant control of certain _OSC features, because they\ndepend on some other _OSC features that have not been requested.\n\nSigned-off-by: Rafael J.
