* slub: Determine gfpflags once and not every time a slab is allocatedChristoph Lameter2008-02-14
| | | | | | | | | | | | Currently we determine the gfp flags to pass to the page allocator each time a slab is being allocated. Determine the bits to be set at the time the slab is created. Store in a new allocflags field and add the flags in allocate_slab().

| * [SCSI] update SG_ALL to avoid causing chainingJames Bottomley2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the sg chaining patches went in, our current value of 255 for SG_ALL excites chaining on some drivers which cannot support it (and would thus oops). Redefine SG_ALL to mean no sg table size preference, but use the single allocation (non chained) limit. This also helps for drivers that use it to size an internal table. We'll do an opt in system later where truly chaining supporting drivers can define their sg_tablesize to be anything up to SCSI_MAX_SG_CHAIN_ELEMENTS.

* | Linux Kernel Markers: create modpost fileMathieu Desnoyers2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.

* | Linux Kernel Markers: support multiple probesMathieu Desnoyers2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCU style multiple probes support for the Linux Kernel Markers. Common case (one probe) is still fast and does not require dynamic allocation or a supplementary pointer dereference on the fast path. - Move preempt disable from the marker site to the callback. Since we now have an internal callback, move the preempt disable/enable to the callback instead of the marker site. Since the callback change is done asynchronously (passing from a handler that supports arguments to a handler that does not setup the arguments is no arguments are passed), we can safely update it even if it is outside the preempt disable section. - Move probe arm to probe connection. Now, a connected probe is automatically armed. Remove MARK_MAX_FORMAT_LEN, unused. This patch modifies the Linux Kernel Markers API : it removes the probe "arm/disarm" and changes the probe function prototype : it now expects a va_list * instead of a "...". If we want to have more than one probe connected to a marker at a given time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it, connecting a second probe handler to a marker will fail. It allow us, for instance, to do interesting combinations : Do standard tracing with LTTng and, eventually, to compute statistics with SystemTAP, or to have a special trigger on an event that would call a systemtap script which would stop flight recorder tracing.

* | moduleparam: fix alpha, ia64 and ppc64 compile failuresIvan Kokshaysky2008-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On alpha, ia64 and ppc64 only relocations to local data can go into read-only sections. The vast majority of module parameters use the global generic param_set_*/param_get_* functions, so the 'const' attribute for struct kernel_param is not only useless, but it also causes compile failures due to 'section type conflict' in those rare cases where param_set/get are local functions.

* | mempolicy: silently restrict nodemask to allowed nodesKOSAKI Motohiro2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kosaki Motohito noted that "numactl --interleave=all ..." failed in the presence of memoryless nodes. This patch attempts to fix that problem. Some background: numactl --interleave=all calls set_mempolicy(2) with a fully populated [out to MAXNUMNODES] nodemask. set_mempolicy() [in do_set_mempolicy()] calls contextualize_policy() which requires that the nodemask be a subset of the current task's mems_allowed; else EINVAL will be returned. A task's mems_allowed will always be a subset of node_states[N_HIGH_MEMORY] i.e., nodes with memory. So, a fully populated nodemask will be declared invalid if it includes memoryless nodes. NOTE: the same thing will occur when running in a cpuset with restricted mem_allowed--for the same reason: node mask contains dis-allowed nodes. mbind(2), on the other hand, just masks off any nodes in the nodemask that are not included in the caller's mems_allowed. In each case [mbind() and set_mempolicy()], mpol_check_policy() will complain [again, resulting in EINVAL] if the nodemask contains any memoryless nodes. This is somewhat redundant as mpol_new() will remove memoryless nodes for interleave policy, as will bind_zonelist()--called by mpol_new() for BIND policy. Proposed fix: 1) modify contextualize_policy logic to: a) remember whether the incoming node mask is empty. b) if not, restrict the nodemask to allowed nodes, as is currently done in-line for mbind(). This guarantees that the resulting mask includes only nodes with memory. NOTE: this is a [benign, IMO] change in behavior for set_mempolicy(). Dis-allowed nodes will be silently ignored, rather than returning an error. c) fold this code into mpol_check_policy(), replace 2 calls to contextualize_policy() to call mpol_check_policy() directly and remove contextualize_policy(). 2) In existing mpol_check_policy() logic, after "contextualization": a) MPOL_DEFAULT: require that in coming mask "was_empty" b) MPOL_{BIND|INTERLEAVE}: require that contextualized nodemask contains at least one node. c) add a case for MPOL_PREFERRED: if in coming was not empty and resulting mask IS empty, user specified invalid nodes. Return EINVAL. c) remove the now redundant check for memoryless nodes 3) remove the now redundant masking of policy nodes for interleave policy from mpol_new(). 4) Now that mpol_check_policy() contextualizes the nodemask, remove the in-line nodes_and() from sys_mbind(). I believe that this restores mbind() to the behavior before the memoryless-nodes patch series. E.g., we'll no longer treat an invalid nodemask with MPOL_PREFERRED as local allocation. [ Patch history: v1 -> v2: - Communicate whether or not incoming node mask was empty to mpol_check_policy() for better error checking. - As suggested by David Rientjes, remove the now unused cpuset_nodes_subset_current_mems_allowed() from cpuset.h v2 -> v3: - As suggested by Kosaki Motohito, fold the "contextualization" of policy nodemask into mpol_check_policy().

* | | | hrtimer: fix *rmtp handling in hrtimer_nanosleep()Oleg Nesterov2008-02-10

This means that if sys_restart_syscall() actually happens and it is interrupted as well, we don't update the user-space variable, but write into the already dead stack frame. Introduced by commit 04c227140fed77587432667a574b14736a06dd7f hrtimer: Rework hrtimer_nanosleep to make sys_compat_nanosleep easier Change the callers to pass "__user *rmtp" to hrtimer_nanosleep(), and change hrtimer_nanosleep() to use copy_to_user() to actually update *rmtp. Small problem remains. man 2 nanosleep states that *rtmp should be written if nanosleep() was interrupted (it says nothing whether it is OK to update *rmtp if nanosleep returns 0), but (with or without this patch) we can dirty *rem even if nanosleep() returns 0. NOTE: this patch doesn't change compat_sys_nanosleep(), because it has other bugs. Fixed by the next patch.

The splitup ended in recursive calls to alloc_pages() when a page for a pte split was requested. Avoid the recursion with a preallocated page pool, which is used to split up large mappings and gets refilled in the return path of kernel_map_pages after the split has been done. The size of the page pool is adjusted to the available memory. This part just implements the page pool and the initialization w/o using it yet.
