[PATCH v9 04/11] arm64: kexec_file: allocate memory walking through memblock list

2018-04-25 Thread AKASHI Takahiro
We need to prevent firmware-reserved memory regions, particularly EFI memory map as well as ACPI tables, from being corrupted by loading kernel/initrd (or other kexec buffers). We also want to support memory allocation in top-down manner in addition to default bottom-up. So let's have arm64
