[PATCH 0/5] xen: fix dom0 PV boot on some AMD machines

[Juergen Gross]

There have been reports of failed boots with Xen due to an overlap of
the kernel's memory with ACPI NVS reported in the E820 map of the host.

This series fixes this issue by moving the NVS area in dom0 to some
higher address.

Juergen Gross (5):
  xen: use correct end address of kernel for conflict checking
  xen: introduce generic helper checking for memory map conflicts
  xen: move checks for e820 conflicts further up
  xen: move max_pfn in xen_memory_setup() out of function scope
  xen: tolerate ACPI NVS memory overlapping with Xen allocated memory
