Changes since v8:

I'm still debugging it, but v9 on the 4.0-rc1 kernel crashes after
calling the UEFI boot time services exit function.  That is, this line:

status = sys_table->boottime->exit_boot_services(handle, mmap_key);

in allocate_new_fdt_and_exit_boot() gets called, and then soon after it
returns, the kernel crashes.  It's really early because the UEFI
exception handler is called.

I did not have this problem with v8 patchset on 3.19.

I tested this patch set on FVP base model with UEFI, and booted ok.
Can you boot the system without this ACPI patch set?

Also, you still have a couple whitespace problems in these patches:

Weired, When I checked the patch locally there were no whitespace
problems:
