arch: remove tile port

2018-03-16T09:56:03Z

The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.

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

2017-11-13T21:05:08Z

Pull perf updates from Ingo Molnar: "The main changes in this cycle were: Kernel: - kprobes updates: use better W^X patterns for code modifications, improve optprobes, remove jprobes. (Masami Hiramatsu, Kees Cook) - core fixes: event timekeeping (enabled/running times statistics) fixes, perf_event_read() locking fixes and cleanups, etc. (Peter Zijlstra) - Extend x86 Intel free-running PEBS support and support x86 user-register sampling in perf record and perf script. (Andi Kleen) Tooling: - Completely rework the way inline frames are handled. Instead of querying for the inline nodes on-demand in the individual tools, we now create proper callchain nodes for inlined frames. (Milian Wolff) - 'perf trace' updates (Arnaldo Carvalho de Melo) - Implement a way to print formatted output to per-event files in 'perf script' to facilitate generate flamegraphs, elliminating the need to write scripts to do that separation (yuzhoujian, Arnaldo Carvalho de Melo) - Update vendor events JSON metrics for Intel's Broadwell, Broadwell Server, Haswell, Haswell Server, IvyBridge, IvyTown, JakeTown, Sandy Bridge, Skylake, SkyLake Server - and Goldmont Plus V1 (Andi Kleen, Kan Liang) - Multithread the synthesizing of PERF_RECORD_ events for pre-existing threads in 'perf top', speeding up that phase, greatly improving the user experience in systems such as Intel's Knights Mill (Kan Liang) - Introduce the concept of weak groups in 'perf stat': try to set up a group, but if it's not schedulable fallback to not using a group. That gives us the best of both worlds: groups if they work, but still a usable fallback if they don't. E.g: (Andi Kleen) - perf sched timehist enhancements (David Ahern) - ... various other enhancements, updates, cleanups and fixes" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (139 commits) kprobes: Don't spam the build log with deprecation warnings arm/kprobes: Remove jprobe test case arm/kprobes: Fix kretprobe test to check correct counter perf srcline: Show correct function name for srcline of callchains perf srcline: Fix memory leak in addr2inlines() perf trace beauty kcmp: Beautify arguments perf trace beauty: Implement pid_fd beautifier tools include uapi: Grab a copy of linux/kcmp.h perf callchain: Fix double mapping al->addr for children without self period perf stat: Make --per-thread update shadow stats to show metrics perf stat: Move the shadow stats scale computation in perf_stat__update_shadow_stats perf tools: Add perf_data_file__write function perf tools: Add struct perf_data_file perf tools: Rename struct perf_data_file to perf_data perf script: Print information about per-event-dump files perf trace beauty prctl: Generate 'option' string table from kernel headers tools include uapi: Grab a copy of linux/prctl.h perf script: Allow creating per-event dump files perf evsel: Restore evsel->priv as a tool private area perf script: Use event_format__fprintf() ...

samples/kretprobe: fix the wrong type

2016-08-04T12:50:07Z

The regs_return_value() returns "unsigned long" or "long" value. But the retval is int type now, it may cause overflow, the log may becomes: [ 2911.078869] do_brk returned -2003877888 and took 4620 ns to execute This patch converts the retval to "unsigned long" type, and fixes the overflow issue.
