#1440844 — Regression in 4.7-rc7

Hi,

Updated the laptop to -rc7 this morning, and it fails to boot. After 
bisecting it, this is the culprit:

commit 45209046c47b93fadf26dc59a9da724f387b9cf2

     ACPICA: Namespace: Fix namespace/interpreter lock ordering

     There is a lock order issue in acpi_load_tables(). The namespace lock
     is held before holding the interpreter lock.

The last I see is grub loading initramfs, after that nothing. Very 
reproducible. Laptop is a Dell XPS 13.

#1441072

We will revert 3 commits to fix this issue.
And re-enable the reverted feature in the future when it is safe to re-enable it.
See this bug for reference:
https://bugzilla.kernel.org/show_bug.cgi?id=121701

Thanks and best regards
-Lv
