Linux has been fixed during 20151218 release cycle by reverting wrong code
in the following commit:
ACPICA commit: 071eff738c59eda1792ac24b3b688b61691d7e7c
Subject: Add per-table execution of module-level code, early region
handlers
While upstream ACPICA fixes later in the following commit:
ACPICA commit: bf6cfddb4784c349f781758981b207253b5a1252

Commit f06147f9fbf1 (ACPICA: Hardware: Enable firmware waking vector
for both 32-bit and 64-bit FACS) added three functions that aren't
present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(),
acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(),
to allow Linux to use the previously existing API for setting the
platform firmware waking vector.However, that wasn't necessary, since the ACPI sleep support code
in Linux can be modified to use the upstream ACPICA's API easily
and the additional functions may be dropped which reduces the code
size and puts the kernel's ACPICA code more in line with the upstream.Make the changes as per the above. While at it, make the relevant
function desctiption comments reflect the upstream ACPICA's ones.Signed-off-by: Rafael J. Wysocki

ACPICA commit 071eff738c59eda1792ac24b3b688b61691d7e7c
Execute any module-level code after each ACPI table (DSDT or SSDT)
is loaded into the namespace (rather than after all AML tables have
been loaded). This matches the behavior of other ACPI
implementations and is required to support BIOS code that
depends on this behavior.Link: https://github.com/acpica/acpica/commit/071eff73

ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8
It is likely that we should synchronously invoke _REG(DISCONNECT) only when
the acpi_remove_address_space_handler() is invoked because of dependencies.
If it is invoked when the object is not referenced, problem may occur
if the operation region fields accessed in _REG are no longer driven by any
device driver.Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of
the handler availability, no return value is required for the caller.This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't
introduce a real change. Lv Zheng.Link: https://github.com/acpica/acpica/commit/1cf1a1e0

…ns can happen during OS early boot stages
ACPICA commit 31178590dde82368fdb0f6b0e466b6c0add96c57
We can ensure no early _REG evaluations by ensuring the following rules in
acpi_ev_execute_reg_method():
1. If an address space handler is installed during early stage,
_REG(CONNECT) evaluations are blocked. This is achieved using
acpi_gbl_reg_methods_enabled which is renamed from
acpi_gbl_reg_methods_executed.
2. If _REG(CONNECT) has never been evalauted for the region object,
_REG(DISCONNECT) evaluations are blocked. This is achieved by a new
region object flag: AOPOBJ_REG_CONNECTED.
Note that, after applying this patch, we can ensure _REG(DISCONNECT) is
always paired to _REG(CONNECT). Lv ZhengLink: https://github.com/acpica/acpica/commit/31178590

This patch introduces a new region initialization function
acpi_ev_associate_reg_method(), which is invoked to associate the _REG method
