Linux creator Linus Torvalds has released version 2.6.26 of the Linux kernel after a lengthy three-month development stretch since the 2.6.25 release involving nine release candidates. In announcing the release on the Linux Kernel Mailing List, Torvalds said the 87 days since 2.6.25 makes 2.6.26 a longer-than-usual release cycle. Torvalds said the changes from release candidate (RC) 9 are small, with the bulk (80 percent) being documentation updates.

S/390 can support nested virtualisation in hardware, I think. You might well be running z/VM on the bare hardware and Linux in guests (I understand this is normal). But this should make it easy to run guest operating systems inside those guests. Since I think the hardware is designed with this in mind, it might not be as prohibitive, performance-wise, as you might think.
One advantage of this would be that you can carve up the machine coarsely using z/VM and give the resulting VMs to various business groups or individuals and then say "If you need more partitioning, use KVM and do it yourself".
I don't know if anybody ever runs Linux on the bare metal hardware. I guess it's not inconceivable that IBM are looking at deprecating z/VM in favour of leveraging Linux+KVM but I'm not sure getting rid of z/VM would be The IBM Way. Just having KVM available for nested virtualisation seems like a useful result in itself, so I assume that's what they're thinking of.
