Merge branch 'perf-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* '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
