The SIE instruction on s390 uses the 2nd half of the page table page to
virtualize the storage keys of a guest. This patch offers the s390_enable_sie
function, which reorganizes the page tables of a single-threaded process to
reserve space in the page t

The address 0x11b8 is used by z/VM for pfault and diag 250 I/O to
provide a 64 bit extint parameter. virtio uses the same address, so
its time to update the lowcore structure.

This patch series introduces a backend for kvm to run on IBM System z
machines (aka s390x) that uses the mainframe's sie virtualization
capability. Many thanks for the review feedback we have received so far,
I do greatly appreciate it!
