RH ES uses 4:4 which is ideal and superior to this hack.
Its a non trivial trade-off. 4/4 lets you run very large physical memory systems much more efficiently than usual but you pay a cost on syscalls and some other events when using the majority of processors. The 4/4 tricks also give most emulations (eg Qemu) serious heartburn trying to emulate %cr3 reloading via mmap and other interfaces with high overhead in relative terms.
Of course AMD64 kind of shot the problem in the head once and for all.
Yep, they sure did. Seriously, the 4:4 option should also be present along with 3:1 and 2:2 splits. You should merge your RH work into this patch and allow both. It would save me one less patch to maintain off the tree.
Alan, you're the man.
