Pull perf tools updates from Arnaldo Carvalho de Melo: "perf annotate: - Add riscv64 support. - Add fusion logic for AMD microarchs. perf record: - Add an option to control the synthesizing behavior: --synth <no|all|task|mmap|cgroup> core: - Allow controlling synthesizing PERF_RECORD_ metadata events during record. - perf.data reader prep work for multithreaded processing. - Fix missing exclude_{host,guest} setting in PMUs that don't support it and that were causing the feature detection code to disable it for all events, even the ones in PMUs that support it. - Fix the default use of precise events on AMD, that were always falling back to non-precise because perf_event_attr.exclude_guest=1 was set and IBS does not have filtering capability, refusing precise + exclude_guest. - Add bitfield_swap() to handle branch_stack endian issue. perf script: - Show binary offsets for userspace addresses in callchains. - Support instruction latency via new "ins_lat" selectable field. - Add dlfilter-show-cycles perf inject: - Add vmlinux and ignore-vmlinux arguments, similar to other tools. perf list: - Display PMU prefix for partially supported hybrid cache events. - Display hybrid PMU events with cpu type. perf stat: - Improve metrics documentation of data structures. - Fix memory leaks in the metric code. - Use NAN for missing event IDs. - Don't compute unused events. - Fix memory leak on error path. - Encode and use metric-id as a metric qualifier. - Allow metrics with no events. - Avoid events for an 'if' constant result. - Only add a referenced metric once. - Simplify metric_refs calculation. - Allow modifiers on metrics. perf test: - Add workload test of metric and metric groups. - Workload test of all PMUs. - vmlinux-kallsyms: Ignore hidden symbols. - Add pmu-event test for event described as "config=". - Verify more event members in pmu-events test. - Add endian test for struct branch_flags on the sample-parsing test. - Improve temp file cleanup in several tests. perf daemon: - Address MSAN warnings on send_cmd(). perf kmem: - Improve man page for record options perf srcline: - Use long-running addr2line per DSO, greatly speeding up the 'srcline' sort order. perf symbols: - Ignore $a/$d symbols for ARM modules. - Fix /proc/kcore access on 32 bit systems. Kernel UAPI copies: - Update copy of linux/socket.h with the kernel sources, no change in tooling output. libbpf: - Pull in bpf_program__get_prog_info_linear() from libbpf, too much specific to perf. - Deprecate bpf_map__resize() in favor of bpf_map_set_max_entries() - Install libbpf headers locally when building. - Bump minimum LLVM C++ std to GNU++14. libperf: - Use binary search in perf_cpu_map__idx() as array are sorted. libtracefs: - Enable libtracefs dynamic linking. libtraceevent: - Increase logging when verbose. Arch specific: * PowerPC: - Add support to expose instruction and data address registers as part of extended regs.

+ * list_sort - sort a list
+ * @priv: private data, opaque to list_sort(), passed to @cmp
+ * @head: the list to sort
+ * @cmp: the elements comparison function
+ *
+ * The comparison function @cmp must return > 0 if @a should sort after
+ * @b ("@a > @b" if you want an ascending sort), and <= 0 if @a should
+ * sort before @b *or* their original order should be preserved.  It is
+ * always called with the element that came first in the input in @a,
+ * and list_sort is a stable sort, so it is not necessary to distinguish
+ * the @a < @b and @a == @b cases.
+ *
+ * This is compatible with two styles of @cmp function:
+ * - The traditional style which returns <0 / =0 / >0, or
+ * - Returning a boolean 0/1.
+ * The latter offers a chance to save a few cycles in the comparison
+ * (which is used by e.g. plug_ctx_cmp() in block/blk-mq.c).
+ *
+ * A good way to write a multi-word comparison is::
+ *
+ *	if (a->high != b->high)
+ *		return a->high > b->high;
+ *	if (a->middle != b->middle)
+ *		return a->middle > b->middle;
+ *	return a->low > b->low;
+ *
+ *
+ * This mergesort is as eager as possible while always performing at least
+ * 2:1 balanced merges.  Given two pending sublists of size 2^k, they are
+ * merged to a size-2^(k+1) list as soon as we have 2^k following elements.
+ *
+ * Thus, it will avoid cache thrashing as long as 3*2^k elements can
+ * fit into the cache.  Not quite as good as a fully-eager bottom-up
+ * mergesort, but it does use 0.2*n fewer comparisons, so is faster in
+ * the common case that everything fits into L1.
+ *
+ *
+ * The merging is controlled by "count", the number of elements in the
+ * pending lists.  This is beautifully simple code, but rather subtle.
+ *
+ * Each time we increment "count", we set one bit (bit k) and clear
+ * bits k-1 .. 0.  Each time this happens (except the very first time
+ * for each bit, when count increments to 2^k), we merge two lists of
+ * size 2^k into one list of size 2^(k+1).
+ *
+ * This merge happens exactly when the count reaches an odd multiple of
+ * 2^k, which is when we have 2^k elements pending in smaller lists,
+ * so it's safe to merge away two lists of size 2^k.
+ *
+ * After this happens twice, we have created two lists of size 2^(k+1),
+ * which will be merged into a list of size 2^(k+2) before we create
+ * a third list of size 2^(k+1), so there are never more than two pending.
+ *
+ * The number of pending lists of size 2^k is determined by the
+ * state of bit k of "count" plus two extra pieces of information:
+ *
+ * - The state of bit k-1 (when k == 0, consider bit -1 always set), and
+ * - Whether the higher-order bits are zero or non-zero (i.e.
+ *   is count >= 2^(k+1)).
+ *
+ * There are six states we distinguish.  "x" represents some arbitrary
+ * bits, and "y" represents some arbitrary non-zero bits:
+ * 0:  00x: 0 pending of size 2^k;           x pending of sizes < 2^k
+ * 1:  01x: 0 pending of size 2^k; 2^(k-1) + x pending of sizes < 2^k
+ * 2: x10x: 0 pending of size 2^k; 2^k     + x pending of sizes < 2^k
+ * 3: x11x: 1 pending of size 2^k; 2^(k-1) + x pending of sizes < 2^k
+ * 4: y00x: 1 pending of size 2^k; 2^k     + x pending of sizes < 2^k
+ * 5: y01x: 2 pending of size 2^k; 2^(k-1) + x pending of sizes < 2^k
+ * (merge and loop back to state 2)
+ *
+ * We gain lists of size 2^k in the 2->3 and 4->5 transitions (because
+ * bit k-1 is set while the more significant bits are non-zero) and
+ * merge them away in the 5->2 transition.  Note in particular that just
+ * before the 5->2 transition, all lower-order bits are 11 (state 3),
+ * so there is one list of each smaller size.
+ *
+ * When we reach the end of the input, we merge all the pending
+ * lists, from smallest to largest.  If you work through cases 2 to
+ * 5 above, you can see that the number of elements we merge with a list
+ * of size 2^k varies from 2^(k-1) (cases 3 and 5 when x == 0) to
+ * 2^(k+1) - 1 (second merge of case 5 when x == 2^(k-1) - 1).

 Instead of collecting non-sample events (for example, fork, comm, mmap) at
 the beginning of record, collect them during finalizing an output file.

+ * Get bpf_prog_info in continuous memory
+ *
+ * struct bpf_prog_info has multiple arrays. The user has option to choose
+ * arrays to fetch from kernel. The following APIs provide an uniform way to
+ * fetch these data. All arrays in bpf_prog_info are stored in a single
+ * continuous memory region. This makes it easy to store the info in a
+ * file.
+ *
+ * Before writing perf_bpil to files, it is necessary to
+ * translate pointers in bpf_prog_info to offsets. Helper functions
+ * bpil_addr_to_offs() and bpil_offs_to_addr()
+ * are introduced to switch between pointers and offsets.
+ *
+ * Examples:
+ *   # To fetch map_ids and prog_tags:
+ *   __u64 arrays = (1UL << PERF_BPIL_MAP_IDS) |
+ *           (1UL << PERF_BPIL_PROG_TAGS);
+ *   struct perf_bpil *info_linear =
+ *           get_bpf_prog_info_linear(fd, arrays);
+ *
+ *   # To save data in file
+ *   bpil_addr_to_offs(info_linear);
+ *   write(f, info_linear, sizeof(*info_linear) + info_linear->data_len);
+ *
+ *   # To read data from file
+ *   read(f, info_linear, <proper_size>);
