The only option is to remove the current\nnoexec support.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "80fe02b5daf176f99d3afc8f6c9dc9dece019836", "tree": "970b90d56870e1b87b4c8efff7ec31fc454445a7", "parents": [ "df48d8716eab9608fe93924e4ae06ff110e8674f", "db670dac49b5423b39b5e523d28fe32045d71b10", "ec514c487c3d4b652943da7b0afbc094eee08cfa" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 19 17:41:22 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 19 17:41:22 2011 -0700" }, "message": "Merge branches \u0027sched-core-for-linus\u0027 and \u0027sched-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027sched-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (60 commits)\n sched: Fix and optimise calculation of the weight-inverse\n sched: Avoid going ahead if -\u003ecpus_allowed is not changed\n sched, rt: Update rq clock when unthrottling of an otherwise idle CPU\n sched: Remove unused parameters from sched_fork() and wake_up_new_task()\n sched: Shorten the construction of the span cpu mask of sched domain\n sched: Wrap the \u0027cfs_rq-\u003enr_spread_over\u0027 field with CONFIG_SCHED_DEBUG\n sched: Remove unused \u0027this_best_prio arg\u0027 from balance_tasks()\n sched: Remove noop in alloc_rt_sched_group()\n sched: Get rid of lock_depth\n sched: Remove obsolete comment from scheduler_tick()\n sched: Fix sched_domain iterations vs. RCU\n sched: Next buddy hint on sleep and preempt path\n sched: Make set_*_buddy() work on non-task entities\n sched: Remove need_migrate_task()\n sched: Move the second half of ttwu() to the remote cpu\n sched: Restructure ttwu() some more\n sched: Rename ttwu_post_activation() to ttwu_do_wakeup()\n sched: Remove rq argument from ttwu_stat()\n sched: Remove rq-\u003elock from the first half of ttwu()\n sched: Drop rq-\u003elock from sched_exec()\n ...\n\n* \u0027sched-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n sched: Fix rt_rq runtime leakage bug\n" }, { "commit": "df48d8716eab9608fe93924e4ae06ff110e8674f", "tree": "0fe10733a414b3651e1dae29518b7960a4da0aa4", "parents": [ "acd30250d7d0f495685d1c7c6184636a22fcdf7f", "29510ec3b626c86de9707bb8904ff940d430289b" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 19 17:36:08 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 19 17:36:08 2011 -0700" }, "message": "Merge branch \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (107 commits)\n perf stat: Add more cache-miss percentage printouts\n perf stat: Add -d -d and -d -d -d options to show more CPU events\n ftrace/kbuild: Add recordmcount files to force full build\n ftrace: Add self-tests for multiple function trace users\n ftrace: Modify ftrace_set_filter/notrace to take ops\n ftrace: Allow dynamically allocated function tracers\n ftrace: Implement separate user function filtering\n ftrace: Free hash with call_rcu_sched()\n ftrace: Have global_ops store the functions that are to be traced\n ftrace: Add ops parameter to ftrace_startup/shutdown functions\n ftrace: Add enabled_functions file\n ftrace: Use counters to enable functions to trace\n ftrace: Separate hash allocation and assignment\n ftrace: Create a global_ops to hold the filter and notrace hashes\n ftrace: Use hash instead for FTRACE_FL_FILTER\n ftrace: Replace FTRACE_FL_NOTRACE flag with a hash of ignored functions\n perf bench, x86: Add alternatives-asm.h wrapper\n x86, 64-bit: Fix copy_[to/from]_user() checks for the userspace address limit\n x86, mem: memset_64.S: Optimize memset by enhanced REP MOVSB/STOSB\n x86, mem: memmove_64.S: Optimize memmove by enhanced REP MOVSB/STOSB\n ...\n" }, { "commit": "83ace2701b81be549cca7af33c5b0499cb2602d6", "tree": "17c74e48a1d67b7691fbdd4955835f16db76ae88", "parents": [ "91d378088b104f8e31baba8c518f32a7a219d58c" ], "author": { "name": "Michael Holzheu", "email": "holzheu@linux.vnet.ibm.com", "time": "Tue May 10 17:13:41 2011 +0200" }, "committer": { "name": "Martin Schwidefsky", "email": "sky@mschwide.boeblingen.de.ibm.com", "time": "Tue May 10 17:13:43 2011 +0200" }, "message": "[S390] replace diag10() with diag10_range() function\n\nCurrently the diag10() function can only release one page.

As the area\nis in .init, there shouldn\u0027t be any noticeable difference.\n\nThis problem was discovered by David Howells while debugging boot\nfailure on mn10300.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nCc: uclinux-dist-devel@blackfin.uclinux.org\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nCc: user-mode-linux-devel@lists.sourceforge.net\n" }, { "commit": "cae5d39032acf26c265f6b1dc73d7ce6ff4bc387", "tree": "9c89bcab3f4c17fb34eb44342d1f67bb4230d632", "parents": [ "83b964bbf82eb13a8f31bb49ca420787fe01f7a6" ], "author": { "name": "Stephen Wilson", "email": "wilsons@start.ca", "time": "Sun Mar 13 15:49:17 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Mar 23 16:36:55 2011 -0400" }, "message": "mm: arch: rename in_gate_area_no_task to in_gate_area_no_mm\n\nNow that gate vma\u0027s are referenced with respect to a particular mm and not a\nparticular task it only makes sense to propagate the change to this predicate as\nwell.\n\nSigned-off-by: Stephen Wilson \u003cwilsons@start.ca\u003e\nReviewed-by: Michel Lespinasse \u003cwalken@google.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: \"H.

When a cpu gets\nofflined it schedules the idle process which, before killing its own cpu,\nwill call tick_nohz_stop_sched_tick().\nThat function in turn will call arch_needs_cpu() in order to check if the\nlocal tick can be disabled. On offline cpus this function should naturally\nreturn 0 since regardless if the tick gets disabled or not the cpu will be\ndead short after. That is besides the fact that __cpu_disable() should already\nhave made sure that no interrupts on the offlined cpu will be delivered anyway.\n\nIn this case it prevents tick_nohz_stop_sched_tick() to call\nselect_nohz_load_balancer(). No idea if that really is a problem. However what\nmade me debug this is that on 2.6.32 the function get_nohz_load_balancer() is\nused within __mod_timer() to select a cpu on which a timer gets enqueued.\nIf arch_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn\u0027t get\nupdated when a cpu gets offlined. It may contain the cpu number of an offline\ncpu. In turn timers get enqueued on an offline cpu and not very surprisingly\nthey never expire and cause system hangs.\n\nThis has been observed 2.6.32 kernels. On current kernels __mod_timer() uses\nget_nohz_timer_target() which doesn\u0027t have that problem. However there might\nbe other problems because of the too early exit tick_nohz_stop_sched_tick()\nin case a cpu goes offline.\n\nThis specific bug was indrocuded with 3c5d92a0 \"nohz: Introduce\narch_needs_cpu\".\n\nIn this case a cpu hotplug notifier is used to fix the issue in order to keep\nthe normal/fast path small. All we need to do is to clear the condition that\nmakes arch_needs_cpu() return 1 since it is just a performance improvement\nwhich is supposed to keep the local tick running for a short period if a cpu\ngoes idle. Nothing special needs to be done except for clearing the condition.\n\nCc: stable@kernel.org\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n" }, { "commit": "e8129c642155616d9e2160a75f103e127c8c3708", "tree": "d863e72afaedfd89939c45ac95c9e02a2c585aa7", "parents": [ "698fd6a2c3ca05ec796072defb5c415289a86cdc" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Thu Nov 25 09:52:45 2010 +0100" }, "committer": { "name": "Martin Schwidefsky", "email": "sky@mschwide.boeblingen.de.ibm.com", "time": "Thu Nov 25 09:52:59 2010 +0100" }, "message": "[S390] nmi: fix clock comparator revalidation\n\nOn each machine check all registers are revalidated.
