git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf updates from Ingo Molnar: "As a first remark I'd like to note that the way to build perf tooling has been simplified and sped up, in the future it should be enough for you to build perf via: cd tools/perf/ make install (ie without the -j option.) The build system will figure out the number of CPUs and will do a parallel build+install. The various build system inefficiencies and breakages Linus reported against the v3.12 pull request should now be resolved - please (re-)report any remaining annoyances or bugs. Main changes on the perf kernel side: * Performance optimizations: . perf ring-buffer code optimizations, by Peter Zijlstra . perf ring-buffer code optimizations, by Oleg Nesterov . x86 NMI call-stack processing optimizations, by Peter Zijlstra . perf context-switch optimizations, by Peter Zijlstra . perf sampling speedups, by Peter Zijlstra . x86 Intel PEBS processing speedups, by Peter Zijlstra * Enhanced hardware support: . for Intel Ivy Bridge-EP uncore PMUs, by Zheng Yan . for Haswell transactions, by Andi Kleen, Peter Zijlstra * Core perf events code enhancements and fixes by Oleg Nesterov: . for uprobes, if fork() is called with pending ret-probes . for uprobes platform support code * New ABI details by Andi Kleen: . Report x86 Haswell TSX transaction abort cost as weight Main changes on the perf tooling side (some of these tooling changes utilize the above kernel side changes): * 'perf report/top' enhancements: . Convert callchain children list to rbtree, greatly reducing the time taken for callchain processing, from Namhyung Kim. . Add new COMM infrastructure, further improving histogram processing, from Frédéric Weisbecker, one fix from Namhyung Kim. . Add /proc/kcore based live-annotation improvements, including build-id cache support, multi map 'call' instruction navigation fixes, kcore address validation, objdump workarounds. From Adrian Hunter. . Show progress on histogram collapsing, that can take a long time, from Namhyung Kim. . Add --max-stack option to limit callchain stack scan in 'top' and 'report', improving callchain processing when reducing the stack depth is an option, from Waiman Long. . Add new option --ignore-vmlinux for perf top, from Willy Tarreau. * 'perf trace' enhancements: . 'perf trace' now can can use a 'perf probe' dynamic tracepoints to hook into the userspace -> kernel pathname copy so that it can map fds to pathnames without reading /proc/pid/fd/ symlinks. From Arnaldo Carvalho de Melo. . Show VFS path associated with fd in live sessions, using a 'vfs_getname' 'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd, from Arnaldo Carvalho de Melo. .

Improve error messages in 'trace', providing hints about system configuration steps needed for using it, from Ramkumar Ramachandra. . 'perf trace' now emits hints as to why tracing is not possible, helping the user to setup the system to allow tracing in the desired permission granularity, telling if the problem is due to debugfs not being mounted or with not enough permission for !root, /proc/sys/kernel/perf_event_paranoit value, etc. From Arnaldo Carvalho de Melo. * 'perf record' enhancements: . Check maximum frequency rate for record/top, emitting better error messages, from Jiri Olsa. . 'perf record' code cleanups, from David Ahern. . Improve write_output error message in 'perf record', from Adrian Hunter. . Allow specifying B/K/M/G unit to the --mmap-pages arguments, from Jiri Olsa. .

Add usage to 'perf list', from David Ahern. . Show error in 'perf list' if tracepoints not available, from Pekka Enberg. * 'perf probe' enhancements: . Support "$vars" meta argument syntax for local variables, allowing asking for all possible variables at a given probe point to be collected when it hits, from Masami Hiramatsu. * 'perf sched' enhancements: . Address the root cause of that 'perf sched' stack initialization build slowdown, by programmatically setting a big array after moving the global variable back to the stack. Fix from Adrian Hunter. * 'perf script' enhancements: . Set up output options for in-stream attributes, from Adrian Hunter. . Print addr by default for BTS in 'perf script', from Adrian Juntmer * 'perf stat' enhancements: .

Up to now PA-RISC could live with a trivial version of access_ok(). Our fault handlers can correctly handle fault cases. But testcases showed that we need a better access check else we won't always return correct errno failure codes to userspace.

We must avoid this since this may run as root. Install targets "ABSOLUTELY MUST NOT MODIFY THE SOURCE TREE." as Linus emphasized this in: http://lkml.org/lkml/2013/7/10/600 So on parisc and maybe other archs we need the same as for x86: 1648e4f8 x86, kbuild: make "make install" not depend on vmlinux This parisc patch was inspired by: 19514fc6 arm, kbuild: make "make install" not depend on vmlinux Signed-off-by: Helge Deller <deller@gmx.de>

2013-11-06uprobes: Introduce arch_uprobe->ixolOleg Nesterov2-1/+5
Currently xol_get_insn_slot() assumes that we should simply copy arch_uprobe->insn[] which is (ignoring arch_uprobe_analyze_insn) just the copy of the original insn. This is not true for arm which needs to create another insn to execute it out-of-line. So this patch simply adds the new member, ->ixol into the union.

2013-11-06x86, hyperv: Move a variable to avoid an unused variable warningH. Peter Anvin1-2/+2

Since the variable is only used inside a small if statement, move the declaration of that variable into the if statement itself. Cc: K. Y.
