Having the x86 patch definitely helps here becauses it potentially exposes the code to many more testers. IMHO it would be good to merge the entire series into 3.2, since the ARM portion fixes an important bug (double mapping of memory ranges with conflicting attributes) that we've lived with for far too long, but it really depends on how everyone sees the risk for regressions here. If something breaks in unfixable ways before the 3.2 release, we can always revert the patches and have another try later. It's also not clear how we should merge it. Ideally the first bunch would go through linux-mm, and the architecture specific patches through the respective architecture trees, but there is an obvious inderdependency between these sets. Russell, Andrew, are you both comfortable with putting the entire set into linux-mm to solve this? Do you see this as 3.2 or rather as 3.3 material?
