      perf diff: Fix usage array, it must end with a NULL entry · 0422a4fc
      Arnaldo Carvalho de Melo authored
      
      
      Fixing this:
      
       [acme@doppio linux-2.6-tip]$ perf diff --hell
         Error: unknown option `hell'
      
        usage: perf diff [<options>] [old_file] [new_file]
       Segmentation fault
       [acme@doppio linux-2.6-tip]$
      
      Also go over the other such arrays to check if they all were OK,
      they are, but there were some minor changes to do like making
      one static and renaming another to match the command it refers
      to.

      hw-breakpoints: Fix hardware breakpoints -> perf events dependency · 99e8c5a3
      Frederic Weisbecker authored
      
      
      The kbuild's select command doesn't propagate through the config
      dependencies.
      
      Hence the current rules of hardware breakpoint's config can't
      ensure perf can never be disabled under us.
      
      We have:
      
      config X86
      	selects HAVE_HW_BREAKPOINTS
      
      config HAVE_HW_BREAKPOINTS
      	select PERF_EVENTS
      
      config PERF_EVENTS
      	[...]
      
      x86 will select the breakpoints but that won't propagate to perf
      events. The user can still disable the latter, but it is
      necessary for the breakpoints.
      
      What we need is:
      
       - x86 selects HAVE_HW_BREAKPOINTS and PERF_EVENTS
       - HAVE_HW_BREAKPOINTS depends on PERF_EVENTS
      
      so that we ensure PERF_EVENTS is enabled and frozen for x86.
      
      This fixes the following kind of build errors:
      
       In file included from arch/x86/kernel/hw_breakpoint.c:31:
       include/linux/hw_breakpoint.h: In function 'hw_breakpoint_addr':
       include/linux/hw_breakpoint.h:39: error: 'struct perf_event' has no member named 'attr'

      perf events: Dont report side-band events on each cpu for per-task-per-cpu events · 5d27c23d
      Peter Zijlstra authored
      
      
      Acme noticed that his FORK/MMAP numbers were inflated by about
      the same factor as his cpu-count.
      
      This led to the discovery of a few more sites that need to
      respect the event->cpu filter.

      perf events, x86/stacktrace: Fix performance/softlockup by providing a special frame pointer-only stack walker
      
      It's just wasteful for stacktrace users like perf to walk
      through every entries on the stack whereas these only accept
      reliable ones, ie: that the frame pointer validates.
      
      Since perf requires pure reliable stacktraces, it needs a stack
      walker based on frame pointers-only to optimize the stacktrace
      processing.
      
      This might solve some near-lockup scenarios that can be triggered
      by call-graph tracing timer events.

      perf events, x86/stacktrace: Make stack walking optional · 61c1917f
      Frederic Weisbecker authored
      
      
      The current print_context_stack helper that does the stack
      walking job is good for usual stacktraces as it walks through
      all the stack and reports even addresses that look unreliable,
      which is nice when we don't have frame pointers for example.
      
      But we have users like perf that only require reliable
      stacktraces, and those may want a more adapted stack walker, so
      lets make this function a callback in stacktrace_ops that users
      can tune for their needs.

      perf probe: Check new event name · b7702a21
      Masami Hiramatsu authored
      
      
      Check new event name is same syntax as a C symbol in perf command.
      In other words, checking the name is as like as other tracepoint
      events.
      
      This can prevent user to create an event with useless name (e.g.
      foo|bar, foo*bar).

      Fix libdwarf include path to fit debian-like systems too.
      
      Borislav Petkov reported:
      
      > even after installing libdwarf-dev on my debian box here,
      > make in tools/perf/ still complains that it cannot find libdwarf:

      This patch adds -I/usr/include/libdwarf to BASIC_CFLAGS
      and fix probe-finder.h to include just libdwarf.h/dwarf.h.
      
      This patch also adds a workaround for the undefined _MIPS_SZLONG

      the start of the code in init_file().
      
      There is in fact one modular use of alloc_file() in the tree, in
      drivers/infiniband/core/uverbs_main.c, so re-add the export to fix:

      [sysctl] Fix breakage on systems with older glibc · 61cf6931
      Andi Kleen authored
      
      
      As predicted during code review, the sysctl(2) changes made systems with
      old glibc nearly unusable.  About every command gives a:
      
        warning: process `ls' used the deprecated sysctl system call with 1.4
      
      warning in the log.
      
      I see this on a SUSE 10.0 system with glibc 2.3.5.
      
      Don't warn for this common case.

      XFS: Free buffer pages array unconditionally · 3fc98b1a
      Dave Chinner authored
      
      
      The code in xfs_free_buf() only attempts to free the b_pages array if the
      buffer is a page cache backed or page allocated buffer. The extra log buffer
      that is used when the log wraps uses pages that are allocated to a different
      log buffer, but it still has a b_pages array allocated when those pages
      are associated to with the extra buffer in xfs_buf_associate_memory.
      
      Hence we need to always attempt to free the b_pages array when tearing
      down a buffer, not just on buffers that are explicitly marked as page bearing
      buffers. This fixes a leak detected by the kernel memory leak code.
