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: (35 commits) perf: Fix unexported generic perf_arch_fetch_caller_regs perf record: Don't try to find buildids in a zero sized file perf: export perf_trace_regs and perf_arch_fetch_caller_regs perf, x86: Fix hw_perf_enable() event assignment perf, ppc: Fix compile error due to new cpu notifiers perf: Make the install relative to DESTDIR if specified kprobes: Calculate the index correctly when freeing the out-of-line execution slot perf tools: Fix sparse CPU numbering related bugs perf_event: Fix oops triggered by cpu offline/online perf: Drop the obsolete profile naming for trace events perf: Take a hot regs snapshot for trace events perf: Introduce new perf_fetch_caller_regs() for hot regs snapshot perf/x86-64: Use frame pointer to walk on irq and process stacks lockdep: Move lock events under lockdep recursion protection perf report: Print the map table just after samples for which no map was found perf report: Add multiple event support perf session: Change perf_session post processing functions to take histogram tree perf session: Add storage for seperating event types in report perf session: Change add_hist_entry to take the tree root instead of session perf record: Add ID and to recorded event data when recording multiple events ...
