ACPICA commit 19f84c249267fab0bfb138bd14d12510fb4faf24
The global variable actually means the availability of the namespace, and
control methods evaluations should happen after namespace readiness. Thus
this patch renames the global variable to reflect this logic. Lv Zheng.

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.

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 Zheng

ACPICA commit 87c85610250ff7141a84507f68dbc1e00f2936db
This patch introduces a new region initialization function
acpi_ev_associate_reg_method(), which is invoked to associate the _REG method
to its related region object.
Region object's default value assignments are also sorted by cleaning up
the code using this new function. Lv Zheng.

ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6
For physical addresses, since the address may exceed 32-bit address range
after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT
and ACPI_FORMAT_UINT64() instead of
ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT().
This patch also removes above replaced macros as there are no users.
This is a preparation to switch acpi_physical_address to 64-bit on 32-bit
kernel builds.

Changes to correct several GPIO issues:
1) The update_rule in a GPIO field definition is now ignored;
a read-modify-write operation is never performed for GPIO fields.
(Internally, this means that the field assembly/disassembly
code is completely bypassed for GPIO.)
2) The Address parameter passed to a GPIO region handler is
now the bit offset of the field from a previous Connection()
operator. Thus, it becomes a "Pin Number Index" into the
Connection() resource descriptor.
3) The bit_width parameter passed to a GPIO region handler is
now the exact bit width of the GPIO field. Thus, it can be
interpreted as "number of pins".
Overall, we can now say that the region handler interface
to GPIO handlers is a raw "bit/pin" addressed interface, not
a byte-addressed interface like the system_memory handler interface.

This change removes some dangerous code that attempts to free the
handler context pointer in some (rare) circumstances. The owner of
the handler owns this pointer and the ACPICA code should never
touch it. Although not seen to be an issue in any kernel, it did
show up as a problem under AcpiExec. Also, set the internal storage
field for the context pointer to zero when the region is deactivated,
simply for sanity. David Box.

This refers to _REG methods under the EC device that have no
corresponding operation region. This is allowed by the ACPI
specification. This update removes a dependency on having an
ECDT table, and will execute an orphan _REG method as long as
the handler for the EC is installed at the EC device node (not
the namespace root). Rui Zhang (original update), Bob Moore
