Hi all!

As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

This was an aid for a transition finished 2007 so not
necessary for some time now, ready for removal.

Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

Christoph Egger

Subject: [PATCH 1/2] Remove transitional, dead GENERIC_CLOCKEVENTS_MIGR

GENERIC_CLOCKEVENTS_MIGR was introduced to facilate transition to the
new codebase which was finished 2007 with
b8ce33590687888ebb900d09557b8807c4539022. However the config Item and
a tiny bit of code wasn't removed back then which is adressed by this
patch.

One might consider getting rid of GENERIC_CLOCKEVENTS_BUILD
alltogether however this patch is limited to changes to affecting the
actual build process in any way.
