Modern pvops linux kernels support a p2m list not covered by the kernel mapping. This capability is flagged by an elf-note specifying the virtual address the kernel is expecting the p2m list to be mapped to. In case the elf-note is set by the kernel don't place the p2m list into the kernel mapping, but map it to the given address. This will allow to support domains with larger memory, as the kernel mapping is limited to 2GB and a domain with huge memory in the TB range will have a p2m list larger than this.
