[PATCH v1 0/3] crashdump/x86: dump dax/kmem and virito-mem added System RAM

Let's properly support dumping any kind of "System RAM" that is not on the
top level of the kernel resource tree in /proc/iomem, processing any
/proc/iomem entry that contains "System RAM". In addition, increase
the maximum number of crash memory ranges to fully support virtio-mem
even in corner cases where we end up with a lot of individual memory
ranges.

David Hildenbrand (3):
  crashdump/x86: dump any kind of "System RAM"
  crashdump/x86: iterate only over actual crash memory ranges
  crashdump/x86: increase CRASH_MAX_MEMORY_RANGES to 32k
