This patch adds a IRQF_IRQPOLL flag.\n\nEach architecture is handled in a separate pach. As I left the irq \u003d\u003d 0 as\ncondition, this should not break existing architectures that use timer_irq \u003d\u003d\n0 and that I did\u0027t address with that patch (because I don\u0027t know).\n\nThis patch:\n\nThis patch adds a IRQF_IRQPOLL flag that the interrupt registration code could\nuse for the interrupt it wants to use for IRQ polling.\n\nBecause this must not be the timer interrupt, an additional flag was added\ninstead of re-using the IRQF_TIMER constant. Until all architectures will\nhave an IRQF_IRQPOLL interrupt, irq \u003d\u003d 0 will stay as alternative as it should\nnot break anything.\n\nAlso, note_interrupt() is called on CPU-specific interrupts to be used as\ninterrupt source for IRQ polling.\n\nSigned-off-by: Bernhard Walle \u003cbwalle@suse.de\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nCc: Grant Grundler \u003cgrundler@google.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bf8f6e5b3e51ee0c64c2d1350c70198ddc8ad3f7", "tree": "c48ebb92f836cfac58465eacc9658fbc2bac4783", "parents": [ "4c4308cb93450989846ac49faeb6dab943e7657e" ], "author": { "name": "Ananth N Mavinakayanahalli", "email": "ananth@in.ibm.com", "time": "Tue May 08 00:34:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:19 2007 -0700" }, "message": "Kprobes: The ON/OFF knob thru debugfs\n\nThis patch provides a debugfs knob to turn kprobes on/off\n\no A new file /debug/kprobes/enabled indicates if kprobes is enabled or\n not (default enabled)\no Echoing 0 to this file will disarm all installed probes\no Any new probe registration when disabled will register the probe but\n not arm it.

Simply moving the check to a\nslightly earlier location (specifically, before the line that actually\nassigns the limit - *old_rlim \u003d new_rlim), does the trick.\n\nDo note that at least the zsh (but not ash, dash, or bash) shell has the\nproblem of \"caching\" the limits set by the ulimit command, so when running\nzsh the fix will not immediately be evident - after entering \"ulimit -t 0\",\n\"ulimit -a\" will show \"-t: cpu time (seconds) 0\", even though the actual\nlimit as returned by getrlimit(...) will be 1. It can be verified by\nopening a subshell (which will not have the values of the parent shell in\ncache) and checking in it, or just by running a CPU intensive command like\n\"echo \u002765536^1048576\u0027 | bc\" and verifying that it dumps core after one\nsecond.\n\nRegardless of whether that is a misfeature in the shell, perhaps it would\nbe better to return -EINVAL from setrlimit in such a case instead of\ncheating and setting to 1, as that does not really reflect the actual state\nof the process anymore.

But, will not cause CPU to come out of idle (just to\nservice this timer), when CPU is idle. Instead, this timer will be\nserviced when CPU eventually wakes up with a subsequent non-deferrable\ntimer.\n\nThe main advantage of this is to avoid unnecessary timer interrupts when\nCPU is idle. If the routine currently called by a timer can wait until\nnext event without any issues, this new timer can be used to setup timer\nevent for that routine. This, with dynticks, allows CPUs to be lazy,\nallowing them to stay in idle for extended period of time by reducing\nunnecesary wakeup and thereby reducing the power consumption.\n\nThis patch:\n\nBuilds this new timer on top of existing timer infrastructure. It uses\nlast bit in \u0027base\u0027 pointer of timer_list structure to store this deferrable\ntimer flag. __next_timer_interrupt() function skips over these deferrable\ntimers when CPU looks for next timer event for which it has to wake up.\n\nThis is exported by a new interface init_timer_deferrable() that can be\ncalled in place of regular init_timer().\n\n[akpm@linux-foundation.org: Privatise a #define]\nSigned-off-by: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Dave Jones \u003cdavej@codemonkey.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d2d9433a4c84c9e7ed78d633fdbffb35d5afda17", "tree": "5a9fb2c9531bec148f21fc499d49493b5576e79c", "parents": [ "c467a388ae9f236c039d4d0f4c4be07c7deebe97" ], "author": { "name": "Dmitry Adamushko", "email": "dmitry.adamushko@gmail.com", "time": "Tue May 08 00:27:31 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:05 2007 -0700" }, "message": "kernel/irq/proc.c: unprotected iteration over the IRQ action list in name_unique()\n\nsetup_irq() releases a desc-\u003elock before calling register_handler_proc(), so\nthe iteration over the IRQ action list is not protected.\n\n(akpm: the check itself is still racy, but at least it probably won\u0027t oops\nnow).\n\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "dd9037a26a1e6ebec9121b4681c414dc77189a90", "tree": "cbce9dc3406943b0026a5de01bd64d42714a9413", "parents": [ "e5f00f42f35e6f4699f105a3bd56874847cbf72f" ], "author": { "name": "Srivatsa Vaddagiri", "email": "vatsa@in.ibm.com", "time": "Tue May 08 00:27:25 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:05 2007 -0700" }, "message": "Fix race between attach_task and cpuset_exit\n\nCurrently cpuset_exit() changes the exiting task\u0027s -\u003ecpuset pointer w/o\ntaking task_lock().

But they have different code paths.\n\nThis patch merges all the nsproxy and its associated namespace copy/clone\nhandling (as much as possible). Posted on container list earlier for\nfeedback.\n\n- Create a new nsproxy and its associated namespaces and pass it back to\n caller to attach it to right process.\n\n- Changed all copy_*_ns() routines to return a new copy of namespace\n instead of attaching it to task-\u003ensproxy.\n\n- Moved the CAP_SYS_ADMIN checks out of copy_*_ns() routines.\n\n- Removed unnessary !ns checks from copy_*_ns() and added BUG_ON()\n just incase.\n\n- Get rid of all individual unshare_*_ns() routines and make use of\n copy_*_ns() instead.\n\n[akpm@osdl.org: cleanups, warning fix]\n[clg@fr.ibm.com: remove dup_namespaces() declaration]\n[serue@us.ibm.com: fix CONFIG_IPC_NS\u003dn, clone(CLONE_NEWIPC) retval]\n[akpm@linux-foundation.org: fix build with CONFIG_SYSVIPC\u003dn]\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nCc: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nCc: \"Eric W.
