Merge pull request #677 from shirou/feature/remove_stolen_from_cpu 
[cpu]: remove unused field Stolen
 2019-05-12 18:43:21 +09:00
Segflow 86c7289ccc Fix: use filename in exec.LookPath instead of full path 
exec.LookPath searches for the file in the $PATH, which mean giving it an absolute path is against it's own purposes.

Laurie Clark-Michalek 413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.

Steven Hartland 6450c60b61 Eliminate use of sysctl command on FreeBSD 
In order to improve performance and help prevent crashes due to the outstanding fork crash bug:
https://github.com/golang/go/issues/15658

Replace string parsed values from the sysctl command with native reads of sysctl values using unix.SysctlRaw and unix.SysctlUint32.

This also merges OpenBSD and FreeBSD load implementations which are identical.
