[PATCH 00/13] xen: support pv-domains larger than 512GB

From: Juergen Gross
Date: Wed Feb 18 2015 - 01:52:20 EST

Support 64 bit pv-domains with more than 512GB of memory.

Tested with 64 bit dom0 on machines with 8GB and 1TB and 32 bit dom0 on a
8GB machine. Conflicts between E820 map and different hypervisor populated
memory areas have been tested via a fake E820 map reserved area on the
8GB machine.

Juergen Gross (13):
xen: sync with xen header
xen: anchor linear p2m list in shared info structure
xen: eliminate scalability issues from initial mapping setup
xen: move static e820 map to global scope
xen: simplify xen_set_identity_and_remap() by using global variables
xen: detect pre-allocated memory interfering with e820 map
xen: find unused contiguous memory area
xen: add service function to copy physical memory areas
xen: check for kernel memory conflicting with memory layout
xen: check pre-allocated page tables for conflict with memory map
xen: move initrd away from e820 non-ram area
xen: if p2m list located in to be remapped region delay remapping
xen: allow more than 512 GB of RAM for 64 bit pv-domains
