[Xen-devel] [PATCH v3] xen/shim: stash RSDP address for ACPI driver

2018-01-22 Thread Wei Liu
It used to the case that we placed RSDP under 1MB and let Xen search for it. We moved the placement to under 4GB in 4a5733771, so the search wouldn't work. Introduce rsdp_hint to ACPI code and set that variable in convert_pvh_info. Signed-off-by: Wei Liu --- Cc: Jan Beulich
