[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.

Fix cpu stats when hw.smt is enabled 
When hw.smt is enabled, and it's enabled by default from 6.4, the
number of cpus given by `runtime.NumCPU()` is half of the total: only
the cpuN with N = 0,2,4,... are used by the system. We need to detect
that and ask for the correct stats.

Get hw.ncpuonline without unix.SysctlUint32 
unix.Sysctl always return an error when asking for hw.ncpuonline, so
revert to a direct unix.Syscall6 to get the cpu count.

fix logic error + little refactor 
Fix: get cptime of n-th cpu when `percpu` instead of the average.

While there, rearrange the last if statement to make the code a bit
more homogeneous.

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.
