offline CPUs\"\n\nThis reverts commit e7b140365b86aaf94374214c6f4e6decbee2eb0a.\n\nCommit e7b14036 removes the targetted disabled CPU from the\ncpu_online_map after calls to migrate_platform_irqs and fixup_irqs.\n\nPaul McKenney states that the reasoning behind the patch was to\nprevent irq handlers from running on CPUs marked offline because:\n\n\tRCU happily ignores CPUs that don\u0027t have their bits set in\n\tcpu_online_map, so if there are RCU read-side critical sections\n\tin the irq handlers being run, RCU will ignore them. If the\n\tother CPUs were running, they might sequence through the RCU\n\tstate machine, which could result in data structures being\n\tyanked out from under those irq handlers, which in turn could\n\tresult in oopses or worse.\n\nUnfortunately, both ia64 functions above look at cpu_online_map to find\na new CPU to migrate interrupts onto. This means we can potentially\nmigrate an interrupt off ourself back to... ourself. Uh oh.\n\nThis causes an oops when we finally try to process pending interrupts on\nthe CPU we want to disable. The oops results from calling __do_IRQ with\na NULL pt_regs:\n\nUnable to handle kernel NULL pointer dereference (address 0000000000000040)\nCall Trace:\n [\u003ca000000100016930\u003e] show_stack+0x50/0xa0\n sp\u003de0000009c922fa00 bsp\u003de0000009c92214d0\n [\u003ca0000001000171a0\u003e] show_regs+0x820/0x860\n sp\u003de0000009c922fbd0 bsp\u003de0000009c9221478\n [\u003ca00000010003c700\u003e] die+0x1a0/0x2e0\n sp\u003de0000009c922fbd0 bsp\u003de0000009c9221438\n [\u003ca0000001006e92f0\u003e] ia64_do_page_fault+0x950/0xa80\n sp\u003de0000009c922fbd0 bsp\u003de0000009c92213d8\n [\u003ca00000010000c7a0\u003e] ia64_native_leave_kernel+0x0/0x270\n sp\u003de0000009c922fc60 bsp\u003de0000009c92213d8\n [\u003ca0000001000ecdb0\u003e] profile_tick+0xd0/0x1c0\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221398\n [\u003ca00000010003bb90\u003e] timer_interrupt+0x170/0x3e0\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221330\n [\u003ca00000010013a800\u003e] handle_IRQ_event+0x80/0x120\n sp\u003de0000009c922fe30 bsp\u003de0000009c92212f8\n [\u003ca00000010013aa00\u003e] __do_IRQ+0x160/0x4a0\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221290\n [\u003ca000000100012290\u003e] ia64_process_pending_intr+0x2b0/0x360\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221208\n [\u003ca0000001000112d0\u003e] fixup_irqs+0xf0/0x2a0\n sp\u003de0000009c922fe30 bsp\u003de0000009c92211a8\n [\u003ca00000010005bd80\u003e] __cpu_disable+0x140/0x240\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221168\n [\u003ca0000001006c5870\u003e] take_cpu_down+0x50/0xa0\n sp\u003de0000009c922fe30 bsp\u003de0000009c9221148\n [\u003ca000000100122610\u003e] stop_cpu+0xd0/0x200\n sp\u003de0000009c922fe30 bsp\u003de0000009c92210f0\n [\u003ca0000001000e0440\u003e] kthread+0xc0/0x140\n sp\u003de0000009c922fe30 bsp\u003de0000009c92210c8\n [\u003ca000000100014ab0\u003e] kernel_thread_helper+0xd0/0x100\n sp\u003de0000009c922fe30 bsp\u003de0000009c92210a0\n [\u003ca00000010000a4c0\u003e] start_kernel_thread+0x20/0x40\n sp\u003de0000009c922fe30 bsp\u003de0000009c92210a0\n\nI don\u0027t like this revert because it is fragile. ia64 is getting lucky\nbecause we seem to only ever process timer interrupts in this path, but\nif we ever race with an IPI here, we definitely use RCU and have the\npotential of hitting an oops that Paul describes above.\n\nPatching ia64\u0027s timer_interrupt() to check for NULL pt_regs is\ninsufficient though, as we still hit the above oops.\n\nAs a short term solution, I do think that this revert is the right\nanswer. The revert hold up under repeated testing (24+ hour test runs)\nwith this setup:\n\n\t- 8-way rx6600\n\t- randomly toggling CPU online/offline state every 2 seconds\n\t- running CPU exercisers, memory hog, disk exercisers, and\n\t network stressors\n\t- average system load around ~160\n\nIn the long term, we really need to figure out why we set pt_regs \u003d NULL\nin ia64_process_pending_intr(). If it turns out that it is unnecessary\nto do so, then we could safely re-introduce e7b14036 (along with some\nother logic to be smarter about migrating interrupts).\n\nOne final note: x86 also removes the disabled CPU from cpu_online_map\nand then re-enables interrupts for 1ms, presumably to handle any pending\ninterrupts:\n\narch/x86/kernel/irq_32.c (and irq_64.c):\ncpu_disable_common:\n\t[remove cpu from cpu_online_map]\n\n\tfixup_irqs():\n\t\tfor_each_irq:\n\t\t\t[break CPU affinities]\n\n\t\tlocal_irq_enable();\n\t\tmdelay(1);\n\t\tlocal_irq_disable();\n\nSo they are doing implicitly what ia64 is doing explicitly.\n\nSigned-off-by: Alex Chiang \u003cachiang@hp.com\u003e\nSigned-off-by: Tony Luck \u003caegl@agluck-desktop.(none)\u003e\n" }, { "commit": "39d481cba27809598e755e184bc0d8ae1d22423e", "tree": "15087a039ccdb05749e099e1a1a7ae39e3887a55", "parents": [ "334f85b647bc46ff4d27ace55aa65f44d6a2f4db" ], "author": { "name": "Robin Holt", "email": "holt@sgi.com", "time": "Tue Feb 03 18:40:59 2009 -0600" }, "committer": { "name": "Tony Luck", "email": "aegl@agluck-desktop.(none)", "time": "Thu Feb 19 11:29:31 2009 -0800" }, "message": "[IA64] bte_copy of BTE_MAX_XFER trips BUG_ON.\n\nBTE_MAX_XFER is wrong.

In case there is appr.\n2GB standby memory present all of usable memory would be used for the\nstruct pages needed for standby memory.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "d5cd0343d2878b66e25e044f644563c6bf708833", "tree": "f5ac4a6f0fe9e37c46d718df0f365b77883184bb", "parents": [ "e2e5a0f2b100a5204d27def8bbf73333d1710be2" ], "author": { "name": "Christian Borntraeger", "email": "borntraeger@de.ibm.com", "time": "Thu Feb 19 15:19:00 2009 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "schwidefsky@de.ibm.com", "time": "Thu Feb 19 15:19:19 2009 +0100" }, "message": "[S390] Fix timeval regression on s390\n\ncommit aa5e97ce4bbc9d5daeec16b1d15bb3f6b7b4f4d4\n[PATCH] improve precision of process accounting.\n\nIntroduced a timing regression:\n-bash-3.2# time ls\nreal 0m0.006s\nuser 0m1.754s\nsys 0m1.094s\n\nThe problem was introduced by an error in cputime_to_timeval.\nCputime is now 1/4096 microsecond, therefore, we have to divide\nthe remainder with 4096 to get the microseconds.\n\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "41f3103fcfffff096c34f5267d7c9a26b44d89d3", "tree": "011bbbc5d7b5e25f2c49ee3de825086b167bc653", "parents": [ "22eb36f49e24e922ca6594a99157a3fcb92d3824" ], "author": { "name": "Russell King", "email": "rmk@dyn-67.arm.linux.org.uk", "time": "Thu Feb 19 13:25:16 2009 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Thu Feb 19 13:25:16 2009 +0000" }, "message": "[ARM] omap: fix clock reparenting in omap2_clk_set_parent()\n\nWhen changing the parent of a clock, it is necessary to keep the\nclock use counts balanced otherwise things the parent state will\nget corrupted.
