arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.

Modules installed outside of the kernel's build system should go into "%s/lib/modules/%s/extra", but at present, perf will only look at them when they are in "%s/lib/modules/%s/kernel". Lets encourage good citizenship by relaxing this requirement to "%s/lib/modules/%s". This way open source modules that are out-of-tree have no incentive to start populating a directory reserved for in-kernel modules and I can stop hex-editing my system's perf binary when profiling OSS out-of-tree modules. Feedback from Namhyung Kim correctly revealed that the hex-edits that I had been doing meant that perf was also traversing the build and source symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly exclude them from traversal with a minor tweak to the traversal routine.

In tests/parse-events.c test cases are declared in evlist_test[] arrays. Elements of arrays are initialized in following pattern: [i] = { .name = ..., .check = ..., }, When perf-test is running with '-v' option, 'i' variable will be printed for every existing test. However, we can't add any arch specific tests inside #ifdefs, because it will create collision between the element number inside #ifdef and the next one outside. This patch adds 'id' field in evlist_test, uses it as a test identifier and removes explicit numbering of array elements. This helps to number tests with gaps.

Trace events potentially can have a '-' in their trace system name, e.g. kvm on s390 defines kvm-s390:* tracepoints. We could not parse them, because there was no rule for this: $ sudo ./perf top -e "kvm-s390:*" invalid or unsupported event: 'kvm-s390:*' This patch adds an extra rule to event_legacy_tracepoint which handles those cases.

Moving towards sharing map groups within a process threads. Because of this we need the map groups to be dynamically allocated. No other functional change is intended in here. Based on a patch by Jiri Olsa, but this time _just_ making the conversion from statically allocating thread->mg to turning it into a pointer and instead of initializing it at thread's constructor, introduce a constructor/destructor for the map_groups class and call at thread creation time.

Currently, accounting each sample is done in multiple places - once when adding them to the input tree, other when adding them to the output tree. It's not only confusing but also can cause a subtle problem since concurrent processing like in perf top might see the updated stats before adding entries into the output tree - like seeing more (blank) lines at the end and/or slight inaccurate percentage. To fix this, only account the entries when it's moved into the output tree so that they cannot be seen prematurely. There're some exceptional cases here and there - they should be addressed separately with comments.

Commit 12e55569 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

Use the previous patch implementation of cpunode_map for builtin-kmem.c Should not be any functional difference.

The system's max configuration is represented by cpu/possible and cpu/kernel_max can be huge (4096 vs. 128), so save space by keeping smaller structures.

This patch figures out the max number of cpus and nodes that are on the system and creates a map of cpu to node. This allows us to provide a cpu and quickly get the node associated with it. It was mostly copied from builtin-kmem.c and tweaked slightly to use less memory (use possible cpus instead of max). It also calculates the max number of nodes.
