3371c19c29 ACPICA: Remove ACPI_GET_OBJECT_TYPE macro
Remove all instances of this obsolete macro, since it is now a
simple reference to ->common.type. There were about 150 invocations
of the macro across 41 files. ACPICA BZ 755.

32c9ef994d ACPICA: Add function to handle PM1 control registers
Added acpi_hw_write_pm1_control. This function writes both of the PM1
control registers (A/B). These registers are different than than
the PM1 A/B status and enable registers in that different values
can be written to the A/B registers.  Most notably, the SLP_TYP
bits can be different, as per the values returned from the _Sx
predefined methods.

ac0c845026 ACPICA: Fix parameter validation for acpi_read/write
Now return AE_BAD_PARAMETER if the input register pointer is
null, and AE_BAD_ADDRESS if the register has an address of zero.
Previously, these cases simply returned AE_OK. For optional
registers such as PM1B status/enable/control, the caller should
check for a valid register address before calling.  ACPICA BZ 748.

aefc7f9a02 ACPICA: For PM1B registers, do not shift value read or written
The PM1B registers are mirrors of the PM1A registers with
different bits actually implemented. From the ACPI specification:
"Although the bits can be split between the two register blocks
(each register block has a unique pointer within the FADT), the bit
positions are maintained. The register block with unimplemented
bits (that is, those implemented in the other register block)
always returns zeros, and writes have no side effects"

227243a04d ACPICA: Remove extra write for acpi_hw_clear_acpi_status
This function was writing an optional PM1B status register
twice.  The existing call to the low-level acpi_hw_register_write
automatically handles a possibly split PM1 A/B register.
ACPICA BZ 751.

c520abadbc ACPICA: Fix writes to optional PM1B registers
On read, shift B register bits above the A bits. On write,
shift B bits down to zero before writing the B register. New:
acpi_hw_read_multiple, acpi_hw_write_multiple. These two functions now
transparently handle the (possible) split registers for PM1 Status,
Enable, and Control.

531c633d2b ACPICA: Split out PM1 status registers from the FADT
Add new globals for the PM1 status registers (A/B), similar to the
way the PM1 enable registers are handled. Instead of overloading
the FADT Event Register blocks. This makes the code clearer and
less prone to error.

7d97277b75 acpi/x86: introduce __apci_map_table, v4
to prevent wrongly overwriting fixmap that still want to use.

ACPI used to rely on low mappings being all linearly mapped and
grew a habit: it never really unmapped certain kinds of tables
after use.

This can cause problems - for example the hypothetical case
when some spurious access still references it.

v2: remove prev_map and prev_size in __apci_map_table
v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to
early_acpi_os_unmap_memory
v4: fix typo in one acpi_get_table_with_size calling

386e4a8358 ACPICA: Fix table entry truncation calculation
During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array.  This array is currently statically defined (see
./drivers/acpi/tables.c).  When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output.  As currently implemented, this message will always
erroneously calculate N as 0.

This patch fixes the calculation that determines how many table entries
will be missing (truncated).

This modification may be used under either the GPL or the BSD-style
license used for Intel ACPI CA code.
