The virtually mapped memory map allows storing struct page objects for
persistent memory devices in pre-allocated storage on those devices.
These 'struct page objects' on devices are also known as metadata.
During libnvdimm/nd_pmem are loading, the previous metadata will
be re-constructed to fit
When the pmem is configured as fsdax, set the vmemmap region as a child
of the namespace region so that it can be registered as a separate
resource later.

The elfcorehdr descirbes the dumpable region in PT_LOADs.
Generally, an iomem resource registered with flags
(IORESOURCE_SYSTEM_RAM | IORESOUCE_BUSY) will be added to PT_LOADs by
kexe_file_load(2). An iomem resource with name prefix "System RAM" will
be added to PT_LOADs in kexec-tools by calling
When the pmem is configured as devdax, set the vmemmap region as a child
of the namespace region so that it can be registered as a separate
resource later.

Add resources with specific flags to PT_LOADs of the elfcorehdr so that
these resources can be dumpable. This change is for kexec_file_load(2)
while kexec_load(2) setups the PT_LOADs according to its parameters
by the callers which usually rely on resources' name from /proc/iomem

It walks resources registered with flags
(IORESOURCE_DEVICE_BACKED_VMEMMAP | IORESOURCE_BUSY), usually used by
device backed vmemmap region. currently, it only sticks to the
persistent memory type since it is only one user.

Hello folks,
Compared with the V2[1] I posted a long time ago, this time it is a
completely new proposal design.
