Pull perf/urgent fixes from Arnaldo Carvalho de Melo: . perf probe: Fix segfault due to testing the wrong pointer for NULL, from Ananth N Mavinakayanahalli. . libtraceevent: Remove hard coded include to /usr/local/include in Makefile, which causes cross builds to include host header files, fix from Jack Mitchell. . perf record: Use the right target interface for synthesizing threads when --cpu/-C option is used, fix from Jiri Olsa. . Check if -DFORTIFY_SOURCE=2 is allowed, as gcc 4.7.2 defines it and then the build is broken when it is redefined in perf, fix from Marcin Slusarz. . Fix build with NO_NEWT=1, that can happen explicitely or when the newt-devel package is not installed, from Michael Ellerman. . perf/POWER7: Create a sysfs format entry for Power7 events, missing patch from a patchseries already merged, from Sukadev Bhattiprolu. . Fix LIBNUMA build with glibc 2.12 and older, from Vinson Lee. Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar

perf tools: Fix LIBNUMA build with glibc 2.12 and older.

2013-03-14T11:06:21Z

The tokens MADV_HUGEPAGE and MADV_NOHUGEPAGE are not available with glibc 2.12 and older. Define these tokens if they are not already defined. This patch fixes these build errors with older versions of glibc.

perf probe: Fix segfault

Fix segfault in perf probe due to a bug introduced by commit d8639f068 (perf tools: Stop using 'self' in strlist).

perf record: Fix -C option

2013-03-13T19:58:28Z

Currently the -C option does not work for record command, because of the targets mismatch when synthesizing threads. Fixing this by using proper target interface for the synthesize decision.

perf tools: check if -DFORTIFY_SOURCE=2 is allowed

2013-03-13T19:57:27Z

It seems gcc (4.7.2) defines _FORTIFY_SOURCE internally and becomes confused when it sees another definition in flags. For me, build failed like this: CHK glibc Makefile:548: *** No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static. Stop. and only with V=1 it printed: :0:0: error: "_FORTIFY_SOURCE" redefined [-Werror] :1:0: note: this is the location of the previous definition Signed-off-by: Marcin Slusarz Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1361113416-8662-1-git-send-email-marcin.slusarz@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

Pull new ARC architecture from Vineet Gupta: "Initial ARC Linux port with some fixes on top for 3.9-rc1: I would like to introduce the Linux port to ARC Processors (from Synopsys) for 3.9-rc1. The patch-set has been discussed on the public lists since Nov and has received a fair bit of review, specially from Arnd, tglx, Al and other subsystem maintainers for DeviceTree, kgdb... The arch bits are in arch/arc, some asm-generic changes (acked by Arnd), a minor change to PARISC (acked by Helge). The series is a touch bigger for a new port for 2 main reasons: 1. It enables a basic kernel in first sub-series and adds ptrace/kgdb/.. later 2. Some of the fallout of review (DeviceTree support, multi-platform- image support) were added on top of orig series, primarily to record the revision history. This updated pull request additionally contains - fixes due to our GNU tools catching up with the new syscall/ptrace ABI - some (minor) cross-arch Kconfig updates." * tag 'arc-v3.9-rc1-late' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: (82 commits) ARC: split elf.h into uapi and export it for userspace ARC: Fixup the current ABI version ARC: gdbserver using regset interface possibly broken ARC: Kconfig cleanup tracking cross-arch Kconfig pruning in merge window ARC: make a copy of flat DT ARC: [plat-arcfpga] DT arc-uart bindings change: "baud" => "current-speed" ARC: Ensure CONFIG_VIRT_TO_BUS is not enabled ARC: Fix pt_orig_r8 access ARC: [3.9] Fallout of hlist iterator update ARC: 64bit RTSC timestamp hardware issue ARC: Don't fiddle with non-existent caches ARC: Add self to MAINTAINERS ARC: Provide a default serial.h for uart drivers needing BASE_BAUD ARC: [plat-arcfpga] defconfig for fully loaded ARC Linux ARC: [Review] Multi-platform image #8: platform registers SMP callbacks ARC: [Review] Multi-platform image #7: SMP common code to use callbacks ARC: [Review] Multi-platform image #6: cpu-to-dma-addr optional ARC: [Review] Multi-platform image #5: NR_IRQS defined by ARC core ARC: [Review] Multi-platform image #4: Isolate platform headers ARC: [Review] Multi-platform image #3: switch to board callback ...
