Anyway, Al summarised the mess here:

And the pile of upstream commits were meant to address the problems 
described AFAIK. It will probably make more sense to associate all these 
related commits to just one CVE name.

I defer to Josh on this, but in a series of patches that is referred to as 
"mremap/mmap mess" in some linux-kernel subject lines, for which a 
specialist like Eugene is not entirely certain about, in which some of the 
patches are assembly-level changes for individual architectures, and where 
few of the patch diffs make it clear what the underlying problem was - we 
could collectively spend a week of labor trying to figure everything out 
from a purist CVE perspective, or anchor on a single series of commits that 
are hopefully attached to a single kernel RC or minor version release.  I 
suspect the latter would be more helpful to the general CVE consumer 
community, so my recommendation is for a single CVE, assuming that all of 
these patches make it into a single kernel update.

They are all in the 2.6.32.4 release.

thanks,
