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 were already merged into RC4 by Rafael.

- Split patch "Parse FADT table to get PSCI flags for PSCI init"
into two as Lorenzo's suggestion, also fix typo and lack of __init
for psci_0_2_set_functions() which is spotted by Lorenzo.

- Add Tested-by from Yijing Wang.

previous version is here:
v6: https://lkml.org/lkml/2015/1/4/40

1. Why we need ACPI on ARM64?

- Grant already posted a blog about this, and stated clearly
why we need ACPI on ARM64:

2. What we need to do before the arm64 ACPI core patches
could be merged into the kernel?

- Al Stone posted a TODO list and updates v2 for the
progress we made:
http://www.spinics.net/lists/arm-kernel/msg390069.html

- so from the progress we can see that we already finished
most of the items, and _OSI we got a plan to fix it, RFC
patch is on the way.

This patch set was tested on FVP by Fuwei, and booted ok as expected.
(No functional change since last version)

Thanks
Hanjun
