* [S390] Add oops_enter()/oops_exit() calls to die().Heiko Carstens2007-06-19
| | | | | | | | | | This is mainly to switch off all potentially debugging stuff that won't report anything useful after an oops happened. Besided that setting pause_on_oops will work too, but doesn't make too much sense on s390.

* [PATCH] audit signal recipientsAmy Griffis2007-05-11
| | | | | | | | | | | | | When auditing syscalls that send signals, log the pid and security context for each target process. Optimize the data collection by adding a counter for signal-related rules, and avoiding allocating an aux struct unless we have more than one target process. For process groups, collect pid/context data in blocks of 16. Move the audit_signal_info() hook up in check_kill_permission() so we audit attempts where permission is denied.

Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.

* | Add suspend-related notifications for CPU hotplugRafael J. Wysocki2007-05-09
|/ | | | | | | | | | | | | | | | | | | | | Since nonboot CPUs are now disabled after tasks and devices have been frozen and the CPU hotplug infrastructure is used for this purpose, we need special CPU hotplug notifications that will help the CPU-hotplug-aware subsystems distinguish normal CPU hotplug events from CPU hotplug events related to a system-wide suspend or resume operation in progress. This patch introduces such notifications and causes them to be used during suspend and resume transitions. It also changes all of the CPU-hotplug-aware subsystems to take these notifications into consideration (for now they are handled in the same way as the corresponding "normal" ones).

* Kprobes: The ON/OFF knob thru debugfsAnanth N Mavinakayanahalli2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a debugfs knob to turn kprobes on/off o A new file /debug/kprobes/enabled indicates if kprobes is enabled or not (default enabled) o Echoing 0 to this file will disarm all installed probes o Any new probe registration when disabled will register the probe but not arm it. A message will be printed out in such a case. o When a value 1 is echoed to the file, all probes (including ones registered in the intervening period) will be enabled o Unregistration will happen irrespective of whether probes are globally enabled or not. o Update Documentation/kprobes.txt to reflect these changes. While there also update the doc to make it current. We are also looking at providing sysrq key support to tie to the disabling feature provided by this patch.

* move die notifier handling to common codeChristoph Hellwig2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

* Introduce CONFIG_HAS_DMAHeiko Carstens2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Architectures that don't support DMA can say so by adding a config NO_DMA to their Kconfig file. This will prevent compilation of some dma specific driver code. Also dma-mapping-broken.h isn't needed anymore on at least s390. This avoids compilation and linking of otherwise dead/broken code. Other architectures that include dma-mapping-broken.h are arm26, h8300, m68k, m68knommu and v850. If these could be converted as well we could get rid of the header file.

* [NET]: Remove NETIF_F_INTERNAL_STATS, default to internal stats.Rusty Russell2007-04-29
| | | | | | | | | | | Herbert Xu conviced me that a new flag was overkill; every driver currently overrides get_stats, so we might as well make the internal one the default. If someone did fail to set get_stats, they would now get all 0 stats instead of "No statistics available".

| | | | | | | | | | | | | | | | | | | | | | | | Allow s390 to properly override the generic __div64_32() implementation by: 1) Using obj-y for div64.o in s390's makefile instead of lib-y 2) Adding the weak attribute to the generic implementation. Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NET]: Inline net_device_statsRusty Russell2007-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Network drivers which keep stats allocate their own stats structure then write a get_stats() function to return them. It would be nice if this were done by default. 1) Add a new "stats" field to "struct net_device". 2) Add a new feature field to say "this driver uses the internal one" 3) Have a default "get_stats" which returns NULL if that feature not set. 4) Change callers to check result of get_stats call for NULL, not if ->get_stats is set. This should not break backwards compatibility with older drivers, yet allow modern drivers to shed some boilerplate code. Lightly tested: works for a modified lguest network driver.
