From: Mark Salter <redacted> The acpi_os_ioremap() function may be used to map normal RAM or IO regions. The current implementation simply uses ioremap_cache(). This will work for some architectures, but arm64 ioremap_cache() cannot be used to map IO regions which don't support caching. So for arm64, use ioremap() for non-RAM regions.
