This flag is a no-op now (see commit 47b0eeb3dc8a "clk: Deprecate
CLK_IS_ROOT", 2016-02-02) so remove it.

Based on v16 of device-tree NUMA patch set for arm64 [1],this patch
set introduce the ACPI based configuration to provide NUMA
information.
ACPI 5.1 already introduced NUMA support for ARM64, which can get the
NUMA domain information from SRAT and SLIT table, so parse those two

ACPI_DEBUG_PRINT is a bit fragile in acpi/numa.c, the first thing
is that component ACPI_NUMA(0x8000) is not described in the
Documentation/acpi/debug.txt, and even not defined in the struct
acpi_dlayer acpi_debug_layers which we can not dynamically enable/disable
it with /sy
From: Hanjun Guo
Identical implementations of acpi_numa_slit_init() are used by both
x86 and follow-on arm64 support. Move it to drivers/acpi/numa.c, and
guard with CONFIG_X86 || CONFIG_ARM64 because ia64 has its own
architecture specific implementation.
No code change.

Loosely based on code from Robert Richter and Hanjun Guo.
Improve out of range node detection as well as allow for Larger SRAT
entities.
Add printing of nice messages.

acpi_numa_memory_affinity_init() will be reused by arm64. Move it to
drivers/acpi/numa.c to facilitate reuse.

Introduce a new file to hold ACPI based NUMA information parsing from
SRAT and SLIT.
SRAT includes the CPU ACPI ID to Proximity Domain mappings and memory
ranges to Proximity Domain mapping. SLIT has the information of inter
node distances(relative number for access latency).
From: Robert Richter
Since acpi_numa_arch_fixup() is only used in arch ia64, move it there
to make a generic interface easier. This avoids empty function stubs
or some complex kconfig options for x86 and arm64.
