There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phy in the private structure, and update the driver to use the one contained in struct net_device.

2016-07-04perf buildid-cache: Scan and import user SDT events to probe cacheMasami Hiramatsu
perf buildid-cache --add <binary> scans given binary and add the SDT events to probe cache. "sdt_" prefix is appended for all SDT providers to avoid event-name clash with other pre-defined events. It is possible to use the cached SDT events as other cached events, via perf probe --add "sdt_<provider>:<event>=<event>". e.g. ---- # perf buildid-cache --add /lib/libc-2.17.so # perf probe --cache --list | head -n 5 /usr/lib/libc-2.17.so (a6fb821bdf53660eb2c29f778757aef294d3d392): sdt_libc:setjmp=setjmp sdt_libc:longjmp=longjmp sdt_libc:longjmp_target=longjmp_target sdt_libc:memory_heap_new=memory_heap_new # perf probe -x /usr/lib/libc-2.17.so \ -a sdt_libc:memory_heap_new=memory_heap_new Added new event: sdt_libc:memory_heap_new (on memory_heap_new in /usr/lib/libc-2.17.so) You can now use it in all perf tools, such as: perf record -e sdt_libc:memory_heap_new -aR sleep 1 # perf probe -l sdt_libc:memory_heap_new (on new_heap+183 in /usr/lib/libc-2.17.so) ---- Note that SDT event entries in probe-cache file is somewhat different from normal cached events. Normal one starts with "#", but SDTs are starting with "%".

2016-07-04perf probe: Add group name supportMasami Hiramatsu
Allow user to set group name for adding new event. Note that user must ensure that the group name doesn't conflict with existing group name carefully. E.g. Existing group name can conflict with other events. Especially, using the group name reserved for kernel modules can hide kernel embedded events when loading modules.

2016-07-04perf sdt: ELF support for SDTHemant Kumar
This patch serves the initial support to identify and list SDT events in binaries. When programs containing SDT markers are compiled, gcc with the help of assembler directives identifies them and places them in the section ".note.stapsdt". To find these markers from the binaries, one needs to traverse through this section and parse the relevant details like the name, type and location of the marker. Also, the original location could be skewed due to the effect of prelinking. If that is the case, the locations need to be adjusted. The functions in this patch open a given ELF, find out the SDT section, parse the relevant details, adjust the location (if necessary) and populate them in a list. A typical note entry in ".note.stapsdt" section is as follows : |--nhdr.n_namesz--| ------------------------------------ | nhdr | "stapsdt" | ----- |----------------------------------| | | <location> <base_address> | | | <semaphore> | nhdr.n_descsize | "provider_name" "note_name" | | | <args> | ----- |----------------------------------| | nhdr | "stapsdt" | |... The above shows an excerpt from the section ".note.stapsdt". 'nhdr' is a structure which has the note name size (n_namesz), note description size (n_desc_sz) and note type (n_type). So, in order to parse the note note info, we need nhdr to tell us where to start from. As can be seen from <sys/sdt.h>, the name of the SDT notes given is "stapsdt". But this is not the identifier of the note. After that, we go to description of the note to find out its location, the address of the ".stapsdt.base" section and the semaphore address. Then, we find the provider name and the SDT marker name and then follow the arguments.
