Well, on the one hand, they fix real bugs in the L3 cache index disable
code and since they're bugfixes, they are eligible late -rc candidates.

On the other hand, however and more importantly, the machines which
have that feature are not selling yet so postponing the patches for the
next merge window is still ok. I'll backport them then to .32 for the
distro kernels and .33 and I think we are going to be fine this way.

So queueing them for .34 is still fine with me, thanks.
