This series of commits converts non-modular code that is using

The suspend.o is built for SUSPEND -- which is bool, and hence

The inner loop in fb8-toggle-cursor can be implemented with hv-logical-memop

Let's introduce a per-board helper:
- board-js2x: slow RB based, taken from current fb8-toggle-cursor
- board-qemu: faster hv-logical-memop based

The inner loop deals with a contiguous region. It could easily be replaced
by faster board specific functions like hv-logical-memop in board-qemu.
Since hv-logical-memop does not return an address, let's have the enclosing

Hi everyone,
there is a potential bug with KVM and hugetlbfs if the hardware does not
support hugepages (EDAT1).
We fix this by making EDAT1 a hard requirement for hugepages and
therefore removing and simplifying code.
As s390, with the sw-emulated hugepages, was the only user of
arch_prepare/r
With s390 dropping support for emulated hugepages, the last user of
arch_prepare_hugepage and arch_release_hugepage is gone.

By dropping support for hugepages on machines which do not have
the hardware feature EDAT1, we fix a potential s390 KVM bug.
The bug would happen if a guest is backed by hugetlbfs (not supported
currently),
but does not get pagetables with PGSTE.
This would lead to random memory overwrites.
