Seems like a new sparse fixed some sparse issues and reveals that the
above was a mistake and should be reverted.

Either this patch
f7750a79568788473c5e8092ee58a52248f34329 x86, mpparse, x86/acpi,
x86/PCI, x86/dmi, SFI: Use memremap() for RAM mappings
shouldn't change to memremap(), or
void __iomem __ref *acpi_os_map_iomem(acpi_physical_address phys,
acpi_size size);
void __ref acpi_os_unmap_iomem(void __iomem *virt, acpi_size size);
Should be cleaned so they either not working with __iomem, or in
special cases force address space for above mentioned functions.

This patch is required for proper functioning of SME/SEV support and
should not be reverted.
