  "message": "[xen] Fix MMIO BAR usage in 64-bit builds\n\nThe HVM MMIO BAR contains no actual MMIO registers, and exists only to\nprovide a chunk of guest physical address space that can be mapped via\nxenmem_add_to_physmap().\n\nThe existing code relies on virt_to_phys() to calculate the physical\nframe numbers (PFNs) to be mapped.  This fails on platforms such as\nx86_64 BIOS where virt_to_phys() is undefined for MMIO space.\n\nFix by mapping the whole MMIO BAR once at probe time, allowing a\nvirtual address within the mapping to be used to determine the\nunderlying physical address.\n\nSigned-off-by: Michael Brown \u003cmcb30@ipxe.org\u003e\n",
