| * Fix on_each_cpu() call for kernels >2.6.26.Josh Stone2008-07-243-0/+12
| | | | | | | | | | | | | | | | This is a generalization of the patch from James Bottomley: http://sources.redhat.com/ml/systemtap/2008-q3/msg00220.html The on_each_cpu() change was merged *after* the 2.6.26 release, so I'm using an autoconf test instead of James' version check.

* Add prototypes for using the 2.6.26 probe_kernel_* functions.Josh Stone2008-05-273-35/+105
| | | | | | | | | For now, the autoconf for the new code is disabled, because it shows poorer performance than our existing dereferencing functions. This is probably because ours get inlined and optimized. The code is being committed so that we may re-evaluate its usefulness in the future. This addresses bugzilla 6432.
