      Merge tag 'perf-core-for-mingo-5.1-20190311' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
      
      Pull perf/core improvements and fixes from Arnaldo:
      
      kernel:
      
        Stephane Eranian :
      
        - Restore mmap record type correctly when handling PERF_RECORD_MMAP2
          events, as the same template is used for all the threads interested
          in mmap events, some may want just PERF_RECORD_MMAP, while some
          may want the extra info in MMAP2 records.
      
      perf probe:
      
        Adrian Hunter:
      
        - Fix getting the kernel map, because since changes related to x86 PTI
          entry trampolines handling, there are more than one kernel map.
      
      perf script:
      
        Andi Kleen:
      
        - Support insn output for normal samples, i.e.:
      
          perf script -F ip,sym,insn --xed
      
          Will fetch the sample IP from the thread address space and feed it
          to Intel's XED disassembler, producing lines such as:
      
            ffffffffa4068804 native_write_msr            wrmsr
            ffffffffa415b95e __hrtimer_next_event_base   movq  0x18(%rax), %rdx
      
          That match 'perf annotate's output.
      
        - Make the --cpu filter apply to  PERF_RECORD_COMM/FORK/... events, in
          addition to PERF_RECORD_SAMPLE.
      
      perf report:
      
        - Add a new --samples option to save a small random number of samples
          per hist entry, using a reservoir technique to select a representative
          number of samples.
      
          Then allow browsing the samples using 'perf script' as part of the hist
          entry context menu. This automatically adds the right filters, so only
          the thread or CPU of the sample is displayed. Then we use less' search
          functionality to directly jump to the time stamp of the selected sample.
      
          It uses different menus for assembler and source display.  Assembler
          needs xed installed and source needs debuginfo.
      
        - Fix the UI browser scripts pop up menu when there are many scripts
          available.
      
      perf report:
      
        Andi Kleen:
      
        - Add 'time' sort option. E.g.:
      
          % perf report --sort time,overhead,symbol --time-quantum 1ms --stdio
          ...

      tools headers:
      
        Arnaldo Carvalho de Melo:
      
        - Update x86's syscall_64.tbl, no change in tools/perf behaviour.
      
        -  Sync copies asm-generic/unistd.h and linux/in with the kernel sources.
      
      perf data:
      
        Jiri Olsa:
      
        - Prep work to support having perf.data stored as a directory, with one
          file per CPU, that ultimately will allow having one ring buffer reading
          thread per CPU.
      
      Vendor events:
      
        Martin Liška:
      
        - perf PMU events for AMD Family 17h.
      
      perf script python:
      
        Tony Jones:
      
        - Add python3 support for the remaining Intel PT related scripts, with
          these we should have a clean build of perf with python3 while still
          supporting the build with python2.
      
      libbpf:
      
        Arnaldo Carvalho de Melo:
      
        - Fix the build on uCLibc, adding the missing stdarg.h since we use
          va_list in one typedef.

      Pull clk subsystem updates from Stephen Boyd:
       "We have a fairly balanced mix of clk driver updates and clk framework
        updates this time around. It's the usual pile of new drivers for new
        hardware out there and the normal small fixes and updates, but then we
        have some core framework changes too.
      
        In the core framework, we introduce support for a clk_get_optional()
        API to get clks that may not always be populated and a way to devm
        manage clkdev lookups registered by provider drivers. We also do some
        refactoring to simplify the interface between clkdev and the common
        clk framework so we can reuse the DT parsing and clk_get() path in
        provider drivers in the future. This work will continue in the next
        few cycles while we convert how providers specify clk parents.
      
        On the driver side, the biggest part of the dirstat is the Amlogic clk
        driver that got support for the G12A SoC. It dominates with almost
        half the overall diff, while the second largest part of the diff is in
        the i.MX clk driver that gained support for imx8mm SoCs. After that,
        we have the Actions Semiconductor and Qualcomm drivers rounding out
        the big part of the dirstat because they both got new hardware support
        for SoCs. The rest is just various updates and non-critical fixes for
        existing drivers.
      
        Core:
         - Convert a few clk bindings to JSON schema format
         - Add a {devm_}clk_get_optional() API
         - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
         - Start rewriting clk parent registration and supporting device links
           by moving around code that supports clk_get() and DT parsing of the
           'clocks' property
      
        New Drivers:
         - Add Qualcomm MSM8998 RPM managed clks
         - IPA clk support on Qualcomm RPMh clk controllers
         - Actions Semi S500 SoC clk support
         - Support for fixed rate clks populated from an MMIO register
         - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
         - Add TMU (timer) clocks on Renesas RZ/G2E
         - Add Amlogic G12A Always-On Clock Controller
         - Add 32k clock generation for Amlogic AXG
         - Add support for the Mali GPU clocks on Amlogic Meson8
         - Add Amlogic G12A EE clock controller driver
         - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E
         - Add i.MX8MM SoC clk driver support
      
        Removed Drivers:
         - Remove clps711x driver as the board support is gone
      
        Updates:
         - 3rd ECO fix for Mediatek MT2712 SoCs
         - Updates for Qualcomm MSM8998 GCC clks
         - Random static analysis fixes for clk drivers
         - Support for sleeping gpios in the clk-gpio type
         - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.)
         - Split LCDC into two clks on the Marvell MMP2 SoC
         - Various DT of_node refcount fixes
         - Get rid of CLK_IS_BASIC from TI code (yay!)
         - TI Autoidle clk support
         - Fix Amlogic Meson8 APB clock ID name
         - Claim input clocks through DT for Amlogic AXG and GXBB
         - Correct the DU (display unit) parent clock on Renesas RZ/G2E
         - Exynos5433 IMEM CMU crypto clk support (SlimSS)

      pptp: dst_release sk_dst_cache in pptp_sock_destruct · 9417d81f
      Xin Long authored
      sk_setup_caps() is called to set sk->sk_dst_cache in pptp_connect,
      so we have to dst_release(sk->sk_dst_cache) in pptp_sock_destruct,
      otherwise, the dst refcnt will leak.
      
      It can be reproduced by this syz log:
      
        r1 = socket$pptp(0x18, 0x1, 0x2)
        bind$pptp(r1, &(0x7f0000000100)={0x18, 0x2, {0x0, @local}}, 0x1e)
        connect$pptp(r1, &(0x7f0000000000)={0x18, 0x2, {0x3, @remote}}, 0x1e)
      
      Consecutive dmesg warnings will occur:
      
        unregister_netdevice: waiting for lo to become free. Usage count = 1
      
      v1->v2:
        - use rcu_dereference_protected() instead of rcu_dereference_check(),
          as suggested by Eric.

      net/tls: Inform user space about send buffer availability · 4504ab0e
      Vakul Garg authored
      A previous fix ("tls: Fix write space handling") assumed that
      user space application gets informed about the socket send buffer
      availability when tls_push_sg() gets called. Inside tls_push_sg(), in
      case do_tcp_sendpages() returns 0, the function returns without calling
      ctx->sk_write_space. Further, the new function tls_sw_write_space()
      did not invoke ctx->sk_write_space. This leads to situation that user
      space application encounters a lockup always waiting for socket send
      buffer to become available.
      
      Rather than call ctx->sk_write_space from tls_push_sg(), it should be
      called from tls_write_space. So whenever tcp stack invokes
      sk->sk_write_space after freeing socket send buffer, we always declare
      the same to user space by the way of invoking ctx->sk_write_space.

      net_sched: return correct value for *notify* functions · 5b5f99b1
      Zhike Wang authored
      It is confusing to directly use return value of netlink_send()/
      netlink_unicast() as the return value of *notify*, as it may be not
      error at all.
      
      Example: in tc_del_tfilter(), after calling tfilter_del_notify(), it will
      goto errout if (err). However, the netlink_send()/netlink_unicast() will
      return positive value even for successful case. So it may not call
      tcf_chain_tp_remove() and so on to clean up the resource, as a result,
      resource is leaked.
      
      It may be easier to only check the return value of tfilter_del_nofiy(),
      but it is more clean to correct all related functions.

      It has been observed that tx queue may stall while downloading

      The cause has been tracked down to a corner case where
      the tx interrupt vector was disabled automatically, but
      was not re enabled later.
      
      The lan743x has two mechanisms to enable/disable individual
      interrupts. Interrupts can be enabled/disabled by individual
      source, and they can also be enabled/disabled by individual
      vector which has been mapped to the source. Both must be
      enabled for interrupts to work properly.
      
      The TX code path, primarily uses the interrupt enable/disable of
      the TX source bit, while leaving the vector enabled all the time.
      
      However, while investigating this issue it was noticed that
      the driver requested the use of the vector auto clear feature.
      
      The test above revealed a case where the vector enable was
      cleared unintentionally.
      
      This patch fixes the issue by deleting the lines that request
      the vector auto clear feature to be used.

      cpuidle: governor: Add new governors to cpuidle_governors again · 22782b3f

      After commit 61cb5758 ("cpuidle: Add cpuidle.governor= command
      line parameter") new cpuidle governors are not added to the list
      of available governors, so governor selection via sysfs doesn't
      work as expected (even though it is rarely used anyway).
      
      Fix that by making cpuidle_register_governor() add new governors to
      cpuidle_governors again.
