Hi,
This is the v7 of ACPI core patches for ARM64 based on ACPI 5.1
updates from v6:
- Rebased on top of 3.19-rc4, add Mack Salter's patch to use
the early_ioremap after paging_init() for ACPI table mappings;
- Two patches about converting apic_id to phys_id to make it arch
agnostic

apic_id in MADT table is the CPU hardware id which identify

acpi_map_lsapic() will allocate a logical CPU number and map it to
physical CPU id (such as APIC id) for the hot-added CPU, it will also
do some mapping for NUMA node id and etc, acpi_unmap_lsapic() will
