2018-03-11selftests: forwarding: Allow creation of interfaces without a config fileIdo Schimmel
Some users want to be able to run the tests without a configuration file which is useful when one needs to test both virtual and physical interfaces on the same machine. Move the defines that set the type of interface to create and whether to create it away from the optional configuration file to the library like the rest of the defines.

2018-03-10tools/memory-model: Finish the removal of rb-dep, ↵Alan Stern
smp_read_barrier_depends(), and lockless_dereference() Commit: bf28ae562744 ("tools/memory-model: Remove rb-dep, smp_read_barrier_depends, and lockless_dereference") was merged too early, while it was still in RFC form. This patch adds in the missing pieces. Akira pointed out some typos in the original patch, and he noted that cheatsheet.txt should indicate that READ_ONCE() now implies an address dependency. Andrea suggested documenting the relationship betwwen unsuccessful RMW operations and address dependencies. Andrea pointed out that the macro for rcu_dereference() in linux.def should now use the "once" annotation instead of "deref". He also suggested that the comments should mention commit: 5a8897cc7631 ("locking/atomics/alpha: Add smp_read_barrier_depends() to _release()/_relaxed() atomics") ... as an important precursor, and he contributed commit: cb13b424e986 ("locking/xchg/alpha: Add unconditional memory barrier to cmpxchg()") which is another prerequisite.

2018-03-09arch: remove score portArnd Bergmann
The Sunplus S+core architecture was added in 2009 by Chen Liqin, who has been co-maintaining it with Lennox Wu <lennox.wu@gmail.com> since then, but after they both left the company, nobody else has shown any interest in the port and it has seen almost no activity other than tree-wide changes. The gcc port was removed a few years ago due to the inactivity. While the sunplus website still advertises products with unspecified RISC cores that might be S+core based, it's very clear that the Linux port is completely abandoned at this point. This removes all files related to the architecture. Acked-by: Lennox Wu <lennox.wu@gmail.com> Link: http://www.sunplus.com/ Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2018-03-09arch: remove m32r portArnd Bergmann
The Mitsubishi/Renesas m32r architecture has been around for many years, but the Linux port has been obsolete for a very long time as well, with the last significant updates done for linux-2.6.14. While some m32r microcontrollers are still being marketed by Renesas, those are apparently no longer possible to support, mainly due to the lack of an external memory interface. Hirokazu Takata was the maintainer until the architecture got marked Orphaned in 2014.

2018-03-09usbip: tools: change to use new error codes in server reply messagesShuah Khan
Changed usbip_network, usbip_attach, usbip_list, and usbipd to use and propagate the new error codes in server reply messages. usbip_net_recv_op_common() is changed to take a pointer to status return the status returned in the op_common.status to callers. usbip_attach and usbip_list use the common interface to print error messages to indicate why the request failed. With this change the messages say why a request failed: - when a client requests a device that is already exported: usbip attach -r server_name -b 3-10.2 usbip: error: Attach Request for 3-10.2 failed - Device busy (exported) - when a client requests a device that isn't exportable, usbip attach -r server_name -b 3-10.4 usbip: error: Attach Request for 3-10.4 failed - Device not found Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Unlike the perf report interactive annotate mode, the perf annotate doesn't display the IPC/Cycle even if branch info is recorded in perf data file. perf record -b ... perf annotate function It should show IPC/cycle, but it doesn't. This patch lets perf annotate support the displaying of IPC/Cycle if branch info is in perf data. For example, perf annotate compute_flag Percent│ IPC Cycle │ │ │ Disassembly of section .text: │ │ 0000000000400640 <compute_flag>: │ compute_flag(): │ volatile int count; │ static unsigned int s_randseed; │ │ __attribute__((noinline)) │ int compute_flag() │ { 22.96 │1.18 584 sub $0x8,%rsp │ int i; │ │ i = rand() % 2; 23.02 │1.18 1 → callq rand@plt │ │ return i; 27.05 │3.37 mov %eax,%edx │ } │3.37 add $0x8,%rsp │ { │ int i; │ │ i = rand() % 2; │ │ return i; │3.37 shr $0x1f,%edx │3.37 add %edx,%eax │3.37 and $0x1,%eax │3.37 sub %edx,%eax │ } 26.97 │3.37 2 ← retq Note that, this patch only supports TUI mode.

2018-03-08perf report: Provide libtraceevent with a kernel symbol resolverWang YanQing
So that beautifiers wanting to resolve kernel function addresses to names can do its work, and when we use "perf report" for output of "perf kmem record", we will get kernel symbol output.

The format of data in MEM_TOPOLOGY is as follows: 0 - version | for future changes 8 - block_size_bytes | /sys/devices/system/memory/block_size_bytes 16 - count | number of nodes For each node we store map of physical indexes for each node: 32 - node id | node index 40 - size | size of bitmap 48 - bitmap | bitmap of memory indexes that belongs to node | /sys/devices/system/node/node<NODE>/memory<INDEX> The MEM_TOPOLOGY could be displayed with following report command: $ perf report --header-only -I ... # memory nodes (nr 1, block size 0x8000000): # 0 [7G]: 0-23,32-69 Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20180307155020.32613-8-jolsa@kernel.org [ Rename 'index' to 'idx', as this breaks the build in rhel5, 6 and other systems where this is used by glibc headers ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

It's passed along several hists entries in --hierarchy mode, so it's better we keep track of it. The current fail I see is that it gets removed in hierarchy --mem-mode mode, where it's shared in the different hierarchies, but removed from the template hist entry, so the report crashes.
