2008-09-16math-emu: Add support for reporting exact invalid exceptionKumar Gala2-4/+27
Some architectures (like powerpc) provide status information on the exact type of invalid exception. This is pretty straight forward as we already report invalid exceptions via FP_SET_EXCEPTION. We add new flags (FP_EX_INVALID_*) the architecture code can define if it wants the exact invalid exception reported. We had to split out the INF/INF and 0/0 cases for divide to allow reporting the two invalid forms properly. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: David S.

2008-09-09lib: Correct printk %pF to work on all architecturesJames Bottomley2-0/+11
It was introduced by "vsprintf: add support for '%pS' and '%pF' pointer formats" in commit 0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2. However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Acked-by: Denis V.

2008-09-06sched: arch_reinit_sched_domains() must destroy domains to force rebuildMax Krasnyansky1-1/+1
What I realized recently is that calling rebuild_sched_domains() in arch_reinit_sched_domains() by itself is not enough when cpusets are enabled. partition_sched_domains() code is trying to avoid unnecessary domain rebuilds and will not actually rebuild anything if new domain masks match the old ones. What this means is that doing echo 1 > /sys/devices/system/cpu/sched_mc_power_savings on a system with cpusets enabled will not take affect untill something changes in the cpuset setup (ie new sets created or deleted). This patch fixes restore correct behaviour where domains must be rebuilt in order to enable MC powersaving flags. Test on quad-core Core2 box with both CONFIG_CPUSETS and !CONFIG_CPUSETS. Also tested on dual-core Core2 laptop. Lockdep is happy and things are working as expected.

2008-09-05sched: fix process time monotonicityBalbir Singh1-0/+4
Spencer reported a problem where utime and stime were going negative despite the fixes in commit b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa. The suspected reason for the problem is that signal_struct maintains it's own utime and stime (of exited tasks), these are not updated using the new task_utime() routine, hence sig->utime can go backwards and cause the same problem to occur (sig->utime, adds tsk->utime and not task_utime()). This patch fixes the problem TODO: using max(task->prev_utime, derived utime) works for now, but a more generic solution is to implement cputime_max() and use the cputime_gt() function for comparison.

2008-09-05clockevents: prevent clockevent event_handler ending up handler_noopVenkatesh Pallipadi1-0/+2
There is a ordering related problem with clockevents code, due to which clockevents_register_device() called after tickless/highres switch will not work. The new clockevent ends up with clockevents_handle_noop as event handler, resulting in no timer activity. The problematic path seems to be * old device already has hrtimer_interrupt as the event_handler * new clockevent device registers with a higher rating * tick_check_new_device() is called * clockevents_exchange_device() gets called * old->event_handler is set to clockevents_handle_noop * tick_setup_device() is called for the new device * which sets new->event_handler using the old->event_handler which is noop. Change the ordering so that new device inherits the proper handler. This does not have any issue in normal case as most likely all the clockevent devices are setup before the highres switch. But, can potentially be affecting some corner case where HPET force detect happens after the highres switch. This was a problem with HPET in MSI mode code that we have been experimenting with.

hwif_to_node() incorrectly assumes that hwif->dev always belongs to a PCI device. This results in ide-cs oopsing in init_irq() after commit c56c5648a3bd15ff14c50f284b261140cd5b5472 accidentally fixed device tree registration for ide-cs. Fix it by using dev_to_node().

The pool lock is also promoted to irq-safe (suggested by Dan). It's necessary because free_pool is now called outside the irq disabled region. So we need to protect against an interrupt handler which calls debug_object_init().

2008-08-29net: Unbreak userspace usage of linux/mroute.hDavid S. Miller4-20/+2
Nothing in linux/pim.h should be exported to userspace. This should fix the XORP build failure reported by Jose Calhariz, the debain package maintainer. Nothing originally in linux/mroute.h was exported to userspace ever, but some of this stuff started to be when it was moved into this new linux/pim.h, and that was wrong. If we didn't provide these definitions for 10 years we can reasonably expect that applications defined this stuff locally or used GLIBC headers providing the protocol definitions. And as such the only result of this can be conflict and userland build breakage. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-27block: move cmdfilter from gendisk to request_queueFUJITA Tomonori2-13/+13
cmd_filter works only for the block layer SG_IO with SCSI block devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI character devices (such as st). We hit a kernel crash with them. The problem is that cmd_filter code accesses to gendisk (having struct blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only SCSI block device files. With character device files, inode->i_bdev leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter isn't safe. SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be independent on any protocols. We shouldn't change ULDs to expose their gendisk. This patch moves struct blk_scsi_cmd_filter from gendisk to request_queue, a common object, which eveyone can access to. The user interface doesn't change; users can change the filters via /sys/block/. gendisk has a pointer to request_queue so the cmd_filter code accesses to struct blk_scsi_cmd_filter.
