/* Use early IO mappings for DMI because it's initialized early */
x86, mpparse, x86/acpi, x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings The ioremap() function is intended for mapping MMIO. For RAM, the memremap() function should be used. Convert calls from ioremap() to memremap() when re-mapping RAM. This will be used later by SME to control how the encryption mask is applied to memory mappings, with certain memory locations being mapped decrypted vs encrypted.
