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:
Applying: ARM64 / ACPI: additions of ACPI documentation for arm64 /local/mnt/workspace/linux.0/.git/rebase-apply/patch:607: new blank line at EOF.
/local/mnt/workspace/linux.0/.git/rebase-apply/patch:844: new blank line at EOF.
warning: 2 lines add whitespace errors. Applying: Documentation: ACPI for ARM64 /local/mnt/workspace/linux.0/.git/rebase-apply/patch:517: new blank line at EOF.

Weired, When I checked the patch locally there were no whitespace problems:
I found those whitespace errors too. Please see the comments in each patch.
