* 'perf-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  perf sched: Fix build failure on sparc
  perf bench: Add "all" pseudo subsystem and "all" pseudo suite
  perf tools: Introduce perf_session class
  perf symbols: Ditch dso->find_symbol
  perf symbols: Allow lookups by symbol name too
  perf symbols: Add missing "Variables" entry to map_type__name
  perf symbols: Add support for 'variable' symtabs
  perf symbols: Introduce ELF counterparts to symbol_type__is_a
  perf symbols: Introduce symbol_type__is_a
  perf symbols: Rename kthreads to kmaps, using another abstraction for it
  perf tools: Allow building for ARM
  hw-breakpoints: Handle bad modify_user_hw_breakpoint off-case return value
  perf tools: Allow cross compiling
  tracing, slab: Fix no callsite ifndef CONFIG_KMEMTRACE
  tracing, slab: Define kmem_cache_alloc_notrace ifdef CONFIG_TRACING

Trivial conflict due to different fixes to modify_user_hw_breakpoint()
in include/linux/hw_breakpoint.h
