[libvirt] [PATCH 0/4] Support for limiting guest coredumps

[Martin Kletzander]

This series applies on the disable_s3/s4 series [1] and works with
qemu patch [2] (not applied yet), so it shouldn't be pushed before
the qemu part is.

Basically qemu supports marking guest memory as (not)dumpable using
madvise(2) system call and in case the guest memory is not desired the
option can reduce the coredump by a reasonable size.
