This requires setting up the full kernel\nGDT and then loading %gs accordingly. We also need to make sure %gs is\ninitialized when bringing up secondary cpus too.\n\nTo keep things consistent, we do the full GDT/segment register setup on\nboth architectures.\n\nBecause we need to avoid -fstack-protected code before setting up the GDT\nand because there\u0027s no way to disable it on a per-function basis, several\nfiles need to have stack-protector inhibited.\n\n[ Impact: allow Xen booting with stack-protector enabled ]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "e07cccf4046978df10f2e13fe2b99b2f9b3a65db", "tree": "086f3d6b72cb6b70ba451c78b8147231d54219c3", "parents": [ "f815c335d21f9965f8dbe142fd168aaba1baf98e" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 05 16:38:12 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 05 16:38:12 2009 -0700" }, "message": "Linux 2.6.31-rc9\n" }, { "commit": "f815c335d21f9965f8dbe142fd168aaba1baf98e", "tree": "4e9a65b7810de10141595125cc65f2b0e7533dfc", "parents": [ "74a01180db4bbfd61304ae0ba1f60af55ffc803d", "baed6b82d9f160184c1c14cdb4accb08f3eb6b87" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 05 14:59:00 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 05 14:59:00 2009 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6:\n firewire: sbp2: fix freeing of unallocated memory\n firewire: ohci: fix Ricoh R5C832, video reception\n firewire: ohci: fix Agere FW643 and multiple cameras\n firewire: core: fix crash in iso resource management\n" }, { "commit": "74a01180db4bbfd61304ae0ba1f60af55ffc803d", "tree": "2f61aac8deb306a164f04a7d2753fbd723c906fc", "parents": [ "5136a6c0fd5b26bbf39ad761cf7a4fc563ad83a3" ], "author": { "name": "Roderick Colenbrander", "email": "thunderbird2k@gmail.com", "time": "Thu Sep 03 09:57:23 2009 -0600" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Sep 05 14:58:07 2009 -0700" }, "message": "powerpc: Fix i8259 interrupt driver kernel crash on ML510\n\nThis patch fixes a null pointer exception caused by removal of\n\u0027ack()\u0027 for level interrupts in the Xilinx interrupt driver.

CPU 1 is where the NMI\nwatchdog triggers.\n\nCPU 0 is submitting mailbox commands fast enough that by the time CPU\n1 returns from the device interrupt handler, a new one is pending.\nThis sequence runs for more than 5 seconds.\n\nThe problematic case is CPU 1\u0027s timer interrupt running when the\nbarrage of device interrupts begin. Then we have:\n\n\ttimer interrupt\n\treturn for softirq checking\n\tpending, thus enable interrupts\n\n\t\t qla2xxx interrupt\n\t\t return\n\t\t qla2xxx interrupt\n\t\t return\n\t\t ... 5+ seconds pass\n\t\t final qla2xxx interrupt for fw load\n\t\t return\n\n\trun timer softirq\n\treturn\n\nAt some point in the multi-second qla2xxx interrupt storm we trigger\nthe NMI watchdog on CPU 1 from the NMI interrupt handler.\n\nThe timer softirq, once we get back to running it, is smart enough to\nrun the timer work enough times to make up for the missed timer\ninterrupts.\n\nHowever, the NMI watchdogs (both x86 and sparc) use the timer\ninterrupt count to notice the cpu is wedged. But in the above\nscenerio we\u0027ll receive only one such timer interrupt even if we last\nall the way back to running the timer softirq.\n\nThe default watchdog trigger point is only 5 seconds, which is pretty\nlow (the softwatchdog triggers at 60 seconds).

A typical SR-IOV\ndevice can support multiple VFs whose BARs must be in a contiguous region,\neffectively an array of VF BARs. The BAR reports the size requirement\nfor a single VF. We calculate the full range needed by simply multiplying\nthe VF BAR size with the number of possible VFs and create a resource\nspanning the full range.\n\nThis all seems sane enough except it artificially inflates the alignment\nrequirement for the VF BAR. The VF BAR need only be aligned to the size\nof a single BAR not the contiguous range of VF BARs. This can cause us\nto fail to allocate resources for the BAR despite the fact that we\nactually have enough space.\n\nThis patch adds a thin PCI specific layer over the generic\nresource_alignment() function which is aware of the special nature of\nVF BARs and does sorting and allocation based on the smaller alignment\nrequirement.\n\nI recognize that while resource_alignment is generic, it\u0027s basically a\nPCI helper. An alternative to this patch is to add PCI VF BAR specific\ninformation to struct resource. I opted for the extra layer rather than\nadding such PCI specific information to struct resource. This does\nhave the slight downside that we don\u0027t cache the BAR size and re-read\nfor each alignment query (happens a small handful of times during boot\nfor each VF BAR).\n\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Yu Zhao \u003cyu.zhao@intel.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "db54501900ad3665dd669f5708ecd04fc5aed495", "tree": "023eac651618698ab37f3e3112f957a07b6192eb", "parents": [ "a09ba7faf75fa4b21980d81de8e5f3d5c0785ccf" ], "author": { "name": "David Müller (ELSOFT AG)", "email": "d.mueller@elsoft.ch", "time": "Sat Aug 29 08:54:45 2009 +0200" }, "committer": { "name": "Eric Anholt", "email": "eric@anholt.net", "time": "Sat Aug 29 18:23:40 2009 -0700" }, "message": "drm/i915: Improve CRTDDC mapping by using VBT info\n\nUse VBT information to determine which DDC bus to use for CRTDCC.\nFall back to GPIOA if VBT info is not available.\n\nSigned-off-by: David Müller \u003cd.mueller@elsoft.ch\u003e\nReviewed-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\nSigned-off-by: Eric Anholt \u003ceric@anholt.net\u003e\nTested on: 855 (David), and 945GM, 965GM, GM45, and G45 (anholt)\n" }, { "commit": "a09ba7faf75fa4b21980d81de8e5f3d5c0785ccf", "tree": "dd0e468fa4a1a287fc365dc5b4ce546b68234377", "parents": [ "f8aed700c6ec46ddade6570004ce25332283b306" ], "author": { "name": "Eric Anholt", "email": "eric@anholt.net", "time": "Sat Aug 29 12:49:51 2009 -0700" }, "committer": { "name": "Eric Anholt", "email": "eric@anholt.net", "time": "Sat Aug 29 17:37:21 2009 -0700" }, "message": "drm/i915: Fix CPU-spinning hangs related to fence usage by using an LRU.\n\nThe lack of a proper LRU was partially worked around by taking the fence\nfrom the object containing the oldest seqno.
