The address check in acpi_hw_get_access_bit_width() should be byte width
based, not bit width based. This patch fixes this mistake.
For those who want to review acpi_hw_access_bit_width(), here is the
concerns and the design details of the function:
It is supposed that the GAS Address field should be aligned to the byte
width indicated by the GAS AccessSize field. Similarly, for the old non
GAS register, it is supposed that its Address should be aligned to its
Length.
For the "AccessSize = 0 (meaning ANY)" case, we try to return the maximum
instruction width (64 for MMIO or 32 for PIO) or the user expected access
bit width (64 for acpi_read()/acpi_write() or 32 for acpi_hw_read()/
acpi_hw_write()) and it is supposed that the GAS Address field should
always be aligned to the maximum expected access bit width (otherwise it
can't be accessed using ANY access bit width).
The problem is in acpi_tb_init_generic_address(), where the non GAS
register's Length is converted into the GAS BitWidth field, its Address is
converted into the GAS Address field, and the GAS AccessSize field is left
0 but most of the registers actually cannot be accessed using "ANY"
accesses.
As a conclusion, when AccessSize = 0 (ANY), the Address should either be
aligned to the BitWidth (wrong conversion) or aligned to 32 for PIO or 64
for MMIO (real GAS). Since currently, max_bit_width is 32, then:
1. BitWidth for the wrong conversion is 8,16,32; and
2. The Address of the real GAS should always be aligned to 8,16,32.
The address alignment check to exclude false matched real GAS is not
necessary. Thus this patch fixes the issue by removing the address
alignment check.
On the other hand, we in fact could use a simpler check of
"reg->bit_width < max_bit_width" to exclude the "BitWidth=64 PIO" case that
may be issued from acpi_read()/acpi_write() in the future.

ACPICA commit c49a751b4dae7baec1790748a2b4b6e8ab599f51
For Access Size = 0, it actually can use user expected access bit width.
This patch implements this.
Besides of the ACPICA upstream commit, this patch also includes a fix fixing
the issue reported by the FreeBSD community.
The old register descriptors are translated in acpi_tb_init_generic_address()
with access_width being filled with 0. This breaks code in
acpi_hw_get_access_bit_width() when the registers are 16-bit IO ports and their
bit_width fields are filled with 16. The rapid fix is meant to make code
written for acpi_hw_get_access_bit_width() regression safer before the issue is
correctly fixed from acpi_tb_init_generic_address(). Reported by
John Baldwin <jhb@freebsd.org>, fixed by Lv Zheng <lv.zheng@intel.com>, tested

ACPICA commit f005ee6b90d152c1f499efcca6b771a93903cb55
This patch splits \_SB._INI evaluation from device initialization code, so
that it can be performed before PCI_Config _REG evaluations. This is
required for the device enumeration process. Some named objects are
initialized in \_SB._INI and PCI_Config _REG evaluations may use
uninitialized named objects because of the order issue.
This must be fixed before fixing ECDT order issue. There are existing
tables allowing ECDT EC to be used for the entire device enumeration
process, but the enabling of ECDT EC is done in \_SB._INI. Thus \_SB._INI
must be the first control method evaluated in the device enumeration
process. Normally, the order should be automatically ensured by the device
enumeration process itself (for example, PCI_Config _REGs are evaluated by
the PCI bus driver when the driver is probed by the enumeration process),
but since the process is split on Linux (partially done in Linux, partially
done in ACPICA), we need to ensure this with special logics in order to be
regression safe. Lv Zheng.

Linux commit: efaed9be99
ACPICA commit: 31178590dde82368fdb0f6b0e466b6c0add96c57
Subject: ACPICA: Events: Enhance acpi_ev_execute_reg_method() to
ensure no _REG evaluations can happen during OS early boot
stages
This is because that the ECDT support is not corrected in Linux, and Linux
requires to execute _REG for ECDT (though this sounds so wrong), we need to
ensure acpi_gbl_namespace_initialized is set before ECDT probing in order
for _REG to be executed. Since we have to move
"acpi_gbl_namespace_initialized = TRUE" to the initialization step
happening before ECDT probing, acpi_load_tables() is the best candidate for
now. Thus this patch fixes the regression by doing so.
But if the ECDT support is fixed, Linux will not execute _REG for ECDT, and
ECDT probing will happen before acpi_load_tables(). At that time, we still
want to ensure acpi_gbl_namespace_initialized is set after executing
acpi_ns_initialize_objects() (under the condition of
acpi_gbl_group_module_level_code = FALSE), this patch also moves
acpi_ns_initialize_objects() to acpi_load_tables() accordingly.
Since acpi_ns_initialize_objects() doesn't seem to be skippable, this
patch also removes ACPI_NO_OBJECT_INIT for the one invoked in
acpi_load_tables(). And since the default region handlers should always be
installed before loading the tables, this patch also removes useless
acpi_gbl_group_module_level_code check accordingly. Reported by Chris
Bainbridge, Fixed by Lv Zheng.

ACPICA commit 77e0c7a482ac30ef857cf3c33d075e5fe5b5e449
This patch tunes _REG evaluations to be later than all table loading
facilities:
1. acpi_load_tables(): _REG is currently invoked after this function.
2. acpi_ns_exec_module_code_list(): this executes module level code, the
execution should be a part of the table loading while we currently
support this in a deferred way.
3. acpi_ns_initialize_objects(): this parses Region/Field/Buffer/Package where
pkg_length primitive can be seen in the grammar, the parsing should be a
part of the table loading while we currently support this in a deferred
way.
Control method evaluation should happen after loading the tables. So this
patch changes the order of _REG evaluation when
acpi_gbl_group_module_level_code experiment is enabled. Lv Zheng.

It is proven that the default regions should be accessible during the

This patch moves default region handler installation code earlier in
order to make this happen.
Note that by putting the code here, we actually allow OSPMs to override
default region handlers between acpi_initialize_subsystem() and
acpi_load_tables(), without the need to introduce region handler override
mechanism in acpi_install_address_space_handler(). OSPMs are also couraged
to check acpi_install_address_space_handler() return value to determine if
acpi_remove_address_space_handler() should be invoked before installing new
address space handler. Lv Zheng.

ACPICA commit 181f56605a771e0b91e24b0648d2565ca70bea20
This is used as a purely infomation message, without module name
and line number information. Therefore, these arguments are
not needed and they are unnecessary overhead.
Arguments are removed.
ACPICA BZ 872.

ACPICA commit 23e644670539e23818fa81e2af5e89ad6657e75c
A failed allocation of new_buffer causes a leak of pld_info
because the error return path fails to free pld_info. Ensure
it is freed on the error exit path.

ACPICA commit 7100a109f7d6523330d29f4d088cf1ffb756025f
Looking at where these are used, this shouldn't result in any behavioral changes, but it's best practices to have them.

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
Subject: Fix for module-level-code regression introduced in 20151218
This results in the divergences and this patch is meant to reduce such
divergences. Lv Zheng.

Commit f06147f9fb (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.
