Add the print-fatal-signals=1 boot option and the /proc/sys/kernel/print-fatal-signals runtime switch. This feature prints some minimal information about userspace segfaults to the kernel console. This is useful to find early bootup bugs where userspace debugging is very hard. Defaults to off. [akpm@linux-foundation.org: Don't add new sysctl numbers] Signed-off-by:

Function proc_register() will assign proc_dir_operations and proc_dir_inode_operations to ent's members proc_fops and proc_iops correctly if ent is a directory. So the early assignment isn't necessary. Cc: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by:

Some users have been having problems with utilities like cp or dd dumping core when they try to copy a file that's too large for the destination filesystem (typically, > 4gb). Apparently, some defunct standards required SIGXFSZ to be sent in such circumstances, but SUS only requires/allows it for when a written file exceeds the process's resource limits. I'd like to limit SIGXFSZs to the bare minimum required by SUS. Patch sent per http://lkml.org/lkml/2007/4/10/302Signed-off-by:

This patch is using mmap()'s randomization functionality in such a way that it maps the main executable of (specially compiled/linked -pie/-fpie) ET_DYN binaries onto a random address (in cases in which mmap() is allowed to perform a randomization). Origin of this patch is in exec-shield (http://people.redhat.com/mingo/exec-shield/) [jkosina@suse.cz: pie randomization: fix BAD_ADDR macro] Signed-off-by:

fs/isofs/* had a bunch of CodingStyle issues. * Indentation was a mix of spaces and tabs * "int * foo" instead of "int *foo" * "while ( foo )" instead of "while (foo)" * if (foo) blah; on one line instead of two * Missing printk KERN_ levels * lots of trailing whitespace * lines >80 columns changed to wrap. * Unnecessary prototype removed by shuffling code order in C file. Should be no functional changes other than slight size increase due to printk changes. Further improvement possible, but this is a start.. Signed-off-by:

Andrew Morton authored
per-cpu counters presently must iterate over all possible CPUs in the exhaustive percpu_counter_sum(). But it can be much better to only iterate over the presently-online CPUs. To do this, we must arrange for an offlined CPU's count to be spilled into the counter's central count. We can do this for all percpu_counters in the machine by linking them into a single global list and walking that list at CPU_DEAD time. (I hope. Might have race windows in which the percpu_counter_sum() count is inaccurate?)

Fix ksoftirqd termination on cpu hotplug with naughty real time process. Assuming the following case: - Try to hot remove CPU2 from CPU1. - There is a real time process on CPU2, and that process doesn't sleep at all. - That rt process and ksoftirqd/2 is migrated to the CPU0 Then ksoftirqd/2 can't stop becasue that rt process runs everlastingly on CPU0, and CPU1 waiting the ksoftirqd/2's termination hangs up. To fix this problem, set the priority of ksoftirqd/2 to max one before kthread_stop(). [akpm@linux-foundation.org: fix warning] Signed-off-by:

stop_machine_run() does its work on "kstopmachine" thread having max priority. However that thread get such priority after woken up. Therefore, in the following case ... - "kstopmachine" try to run on CPU1 - There is a real time process which doesn't relinquish CPU time voluntary on CPU1 ... "kstopmachine" can't start to run and the CPU on which stop_machine_run() is runing hangs up. To fix this problem, call sched_setscheduler() before waking up that thread. Signed-off-by: -

Commit 411187fb caused uptime not to increase during suspend. This may cause confusion so I restore the old behaviour by using the boot based time instead of monotonic for uptime. Signed-off-by:

Commit 411187fb caused boot time to move and process start times to become invalid after suspend. Using boot based time for those restores the old behaviour and fixes the issue. [akpm@linux-foundation.org: little cleanup] Signed-off-by:

Tomas Janousek authored
The commits 411187fb (GTOD: persistent clock support) c1d370e1 (i386: use GTOD persistent clock support) changed the monotonic time so that it no longer jumps after resume, but it's not possible to use it for boot time and process start time calculations then. Also, the uptime no longer increases during suspend. I add a variable to track the wall_to_monotonic changes, a function to get the real boot time and a function to get the boot based time from the monotonic one.

Before calling init_hwif_default, ide_unregister gets lock ide_lock and disables irq. init_hwif_default calls ide_default_io_base which calls pci_get_device and later pci_get_subsys tries to apply for semaphore pci_bus_sem and goes to sleep. Mostly, pci_get_device should be called when irq is turned on. ide_default_io_base just needs find if list pci_devices is empty. Signed-off-by:
