Subject: [PATCH v2 0/2] Add STRICT_DEVMEM support on RISC-V

This patch set adds devmem_is_allowed to support STRICT_DEVMEM. In
devmem_is_allowed, it invokes page_is_ram to check the specific
address whether registered as System RAM in iomem_resource. The resource
initialization is in kexec/kdump patch series which is reviewing,
page_is_ram checking is no use until it is merged.
