commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date:   4 days ago
config: arm64-randconfig-s031-20200622 (attached as .config)
compiler: aarch64-linux-gcc (GCC) 9.3.0
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.2-rc1-18-g27caae40-dirty
        git checkout 670d0a4b10704667765f7d18f7592993d02783aa
        # save the attached .config to linux build tree
        make W=1 C=1 ARCH=arm64 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

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.
