* update checkpatch.pl to version 0.08Andy Whitcroft2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This version brings a number of new checks, and a number of bug fixes. Of note: - warnings for multiple assignments per line - warnings for multiple declarations per line - checks for single statement blocks with braces This patch includes an update for feature-removal-schedule.txt to better target checks. Andy Whitcroft (12): Version: 0.08 only apply printk checks where there is a string literal allow suppression of errors for when no patch is found warn about multiple assignments warn on declaration of multiple variables check for kfree() with needless null check check for single statement braced blocks check for aggregate initialisation on the next line handle the => operator check for spaces between function name and open parenthesis move to explicit Check: entries in feature-removal-schedule.txt handle pointer attributes Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* audit: rework execve auditPeter Zijlstra2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | The purpose of audit_bprm() is to log the argv array to a userspace daemon at the end of the execve system call. Since user-space hasn't had time to run, this array is still in pristine state on the process' stack; so no need to copy it, we can just grab it from there. In order to minimize the damage to audit_log_*() copy each string into a temporary kernel buffer first. Currently the audit code requires that the full argument vector fits in a single packet. So currently it does clip the argv size to a (sysctl) limit, but only when execve auditing is enabled. If the audit protocol gets extended to allow for multiple packets this check can be removed.

* mm: fault feedback #1Nick Piggin2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | Change ->fault prototype. We now return an int, which contains VM_FAULT_xxx code in the low byte, and FAULT_RET_xxx code in the next byte. FAULT_RET_ code tells the VM whether a page was found, whether it has been locked, and potentially other things. This is not quite the way he wanted it yet, but that's changed in the next patch (which requires changes to arch code). This means we no longer set VM_CAN_INVALIDATE in the vma in order to say that a page is locked which requires filemap_nopage to go away (because we can no longer remain backward compatible without that flag), but we were going to do that anyway. struct fault_data is renamed to struct vm_fault as Linus asked. address is now a void __user * that we should firmly encourage drivers not to use without really good reason. The page is now returned via a page pointer in the vm_fault struct.

* mm: merge populate and nopage into fault (fixes nonlinear)Nick Piggin2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nonlinear mappings are (AFAIKS) simply a virtual memory concept that encodes the virtual address -> file offset differently from linear mappings. ->populate is a layering violation because the filesystem/pagecache code should need to know anything about the virtual memory mapping. The hitch here is that the ->nopage handler didn't pass down enough information (ie. pgoff). But it is more logical to pass pgoff rather than have the ->nopage function calculate it itself anyway (because that's a similar layering violation). Having the populate handler install the pte itself is likewise a nasty thing to be doing. This patch introduces a new fault handler that replaces ->nopage and ->populate and (later) ->nopfn. Most of the old mechanism is still in place so there is a lot of duplication and nice cleanups that can be removed if everyone switches over. The rationale for doing this in the first place is that nonlinear mappings are subject to the pagefault vs invalidate/truncate race too, and it seemed stupid to duplicate the synchronisation logic rather than just consolidate the two. After this patch, MAP_NONBLOCK no longer sets up ptes for pages present in pagecache. Seems like a fringe functionality anyway. NOPAGE_REFAULT is removed. This should be implemented with ->fault, and no users have hit mainline yet.

* Report that kernel is tainted if there was an OOPSPavel Emelianov2007-07-17
| | | | | | | | | | | | | | If the kernel OOPSed or BUGed then it probably should be considered as tainted. Thus, all subsequent OOPSes and SysRq dumps will report the tainted kernel. This saves a lot of time explaining oddities in the calltraces.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

* SLUB: change error reporting format to follow lockdep looselyChristoph Lameter2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes the error reporting format to loosely follow lockdep. If data corruption is detected then we generate the following lines: ============================================ BUG <slab-cache>: <problem> -------------------------------------------- INFO: <more information> [possibly multiple times] <object dump> FIX <slab-cache>: <remedial action> This also adds some more intelligence to the data corruption detection. Its now capable of figuring out the start and end. Add a comment on how to configure SLUB so that a production system may continue to operate even though occasional slab corruption occur through a misbehaving kernel component.

* Add a movablecore= parameter for sizing ZONE_MOVABLEMel Gorman2007-07-17
| | | | | | | | | | | | | | | | | | | | | | This patch adds a new parameter for sizing ZONE_MOVABLE called movablecore=. While kernelcore= is used to specify the minimum amount of memory that must be available for all allocation types, movablecore= is used to specify the minimum amount of memory that is used for migratable allocations. The amount of memory used for migratable allocations determines how large the huge page pool could be dynamically resized to at runtime for example. How movablecore is actually handled is that the total number of pages in the system is calculated and a value is set for kernelcore that is kernelcore == totalpages - movablecore Both kernelcore= and movablecore= can be safely specified at the same time.

* handle kernelcore=: genericMel Gorman2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the kernelcore= parameter for x86. Once all patches are applied, a new command-line parameter exist and a new sysctl. This patch adds the necessary documentation. From: Yasunori Goto <y-goto@jp.fujitsu.com> When "kernelcore" boot option is specified, kernel can't boot up on ia64 because of an infinite loop. In addition, the parsing code can be handled in an architecture-independent manner. This patch uses common code to handle the kernelcore= parameter. It is only available to architectures that support arch-independent zone-sizing (i.e. define CONFIG_ARCH_POPULATES_NODE_MAP). Other architectures will ignore the boot parameter.
