arm64: Fix NUMA build error when !CONFIG_ACPI

ctmarinas · ctmarinas · commit bfe6c8a89e03 · 2016-08-17T17:16:58.000+01:00
Since asm/acpi.h is only included by linux/acpi.h when CONFIG_ACPI is enabled, disabling the latter leads to the following build error on arm64: arch/arm64/mm/numa.c: In function ‘arm64_numa_init’: arch/arm64/mm/numa.c:395:24: error: ‘arm64_acpi_numa_init’ undeclared (first use in this function) if (!acpi_disabled && !numa_init(arm64_acpi_numa_init)) This patch include the asm/acpi.h explicitly in arch/arm64/mm/numa.c for the arm64_acpi_numa_init() definition.
