Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar: "A bit larger than what I'd wish for - half of it is due to hw driver updates to Intel Ivy-Bridge which info got recently released, cycles:pp should work there now too, amongst other things. (but we are generally making exceptions for hardware enablement of this type.) There are also callchain fixes in it - responding to mostly theoretical (but valid) concerns. The tooling side sports perf.data endianness/portability fixes which did not make it for the merge window - and various other fixes as well." * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) perf/x86: Check user address explicitly in copy_from_user_nmi() perf/x86: Check if user fp is valid perf: Limit callchains to 127 perf/x86: Allow multiple stacks perf/x86: Update SNB PEBS constraints perf/x86: Enable/Add IvyBridge hardware support perf/x86: Implement cycles:p for SNB/IVB perf/x86: Fix Intel shared extra MSR allocation x86/decoder: Fix bsr/bsf/jmpe decoding with operand-size prefix perf: Remove duplicate invocation on perf_event_for_each perf uprobes: Remove unnecessary check before strlist__delete perf symbols: Check for valid dso before creating map perf evsel: Fix 32 bit values endianity swap for sample_id_all header perf session: Handle endianity swap on sample_id_all header data perf symbols: Handle different endians properly during symbol load perf evlist: Pass third argument to ioctl explicitly perf tools: Update ioctl documentation for PERF_IOC_FLAG_GROUP perf tools: Make --version show kernel version instead of pull req tag perf tools: Check if callchain is corrupted perf callchain: Make callchain cursors TLS ...
