Subject: [PATCH v3 0/2] arm64/acpi: restrict AML opregion memory access
v2:
- do a more elaborate check on the region, against the EFI memory map
v3:
- split into two patches
- fallback to __ioremap() for ACPI reclaim memory, in case it is not covered
by the linear mapping (e.g., when booting a kdump kernel)
Ard Biesheuvel (2):
arm64/acpi: disallow AML memory opregions to access kernel memory
arm64/acpi: disallow writeable AML opregion mapping for EFI code
