This patchset finally brings support of switching between 4- and 5-level
paging modes!
There will be few patches after this to optimize switching and support
mode Xen modes, but this makes the same kernel image to run on both 4- and
5-level machines.
Please review and consider applying.
First 5 patches is split up of the last patch from the previous patchset.
The rest is pretty trivial too.
