Hi Itaru, I have tested kvmram patches (v4.6 and next-20160513) with ACPI/DTB firmware on Qualcomm platforms without any issue. Seems this problem could be related to memory region attributes and typethat contains runtime service code/data and EFI system table. Make sure EFI system table marked as runtime service with right arrtinutes.
