I made this change due to some other explicit requests about the
kernel version not being obvious. I don't really see this as a big
deal, I'm already updating SRCREVs, we are already updating the
SRCREVs in the meta-* layers .. so I fail to see how this is much
more load.

I'd argue that 2.6.37 was a mistake, and you shouldn't even need
to set the preferred version anymore once the latest kernel works
for your machines. It will always be selected and you shouldn't
need to force it. We only needed this during the transition phase,
and I'm about to change the default in meta-yocto .. so you definitely
won't need it.

Cheers,

Bruce
