Shaohua Li 9dc130fccb ACPI: fix OSC regression that caused aer and pciehp not to load
Executing _OSC returns a buffer, which has an acpi object in it.
Don't directly returns the buffer, instead, we return the acpi object's
buffer. This fixes a regression since caller of acpi_run_osc expects
an acpi object's buffer returned.

Alex Chiang 43bab25ced ACPI: processor: change acpi_processor_set_pdc() interface
When calling _PDC, we really only need the handle to the processor
to call the method; we don't look at any other parts of the
struct acpi_processor * given to us.

In the early path, when we walk the namespace, we are given the
handle directly, so just pass it through to acpi_processor_set_pdc()
without stuffing it into a wasteful struct acpi_processor allocated
on the stack each time

This saves 2834 bytes of stack.

Update the interface accordingly.

Alex Chiang 3b407aef57 ACPI: processor: introduce acpi_processor_alloc_pdc()
acpi_processor_init_pdc() isn't really doing anything interesting
with the struct acpi_processor * parameter. Its real job is to allocate
the buffer for the _PDC bits.

So rename the function to acpi_processor_alloc_pdc(), and just return
the struct acpi_object_list * it's supposed to allocate.

Alex Chiang 6c5807d7bc ACPI: processor: finish unifying arch_acpi_processor_init_pdc()
The only thing arch-specific about calling _PDC is what bits get
set in the input obj_list buffer.

There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

Alex Chiang 78f1699659 ACPI: processor: call _PDC early
We discovered that at least one machine (HP Envy), methods in the DSDT
attempt to call external methods defined in a dynamically loaded SSDT.

Unfortunately, the DSDT methods we are trying to call are part of the
EC initialization, which happens very early, and the the dynamic SSDT
is only loaded when a processor _PDC method runs much later.

This results in namespace lookup errors for the (as of yet) undefined
methods.

Since Windows doesn't have any issues with this machine, we take it
as a hint that they must be evaluating _PDC much earlier than we are.

Thus, the proper thing for Linux to do should be to match the Windows
implementation more closely.

Provide a mechanism to call _PDC before we enable the EC. Doing so loads
the dynamic tables, and allows the EC to be enabled correctly.

The ACPI processor driver will still evaluate _PDC in its .add() method
to cover the hotplug case.

                        If (LGreaterEqual (OSFG, OSVT))

                                Subtract (0x0F, Local0, LBTN)
                                ^^^SBRG.EC0.STBR ()
                                ...
                            }
                            Else
                            {
                                DBGR (0x0B, Zero, Zero, Arg0)
                                Store (Arg0, LBTN)

                        }
                    }
LBTN is used to store the index of the brightness level in the _BCL.
GCBL is a method that convert the percentage value to the index value.
If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage
value which is surely beyond the end of _BCL package.

I got following warning on ia64 box:
  In function 'acpi_processor_power_verify':

The problem is that the lapic_timer_propagate_broadcast() has 2 versions:
One is real code that modified in the above commit, and the other is NOP
code that used when !ARCH_APICTIMER_STOPS_ON_C3:

  static void lapic_timer_propagate_broadcast(struct acpi_processor *pr) { }

So I got warning because of !ARCH_APICTIMER_STOPS_ON_C3.

We really want to do nothing here on !ARCH_APICTIMER_STOPS_ON_C3, so
modify lapic_timer_propagate_broadcast() of real version to use
smp_call_function_single() in it.

Bob Moore 3a58176e4f ACPICA: Remove messages if predefined repair(s) are successful
Repair mechanism was considered too wordy. Now, messages are only
unconditionally emitted if the return object cannot be repaired.
Existing messages for successful repairs were converted to
ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.

Bob Moore d976591120 ACPICA: Fix mutex errors when running _REG methods
Fixes a problem where mutex errors can occur when running a _REG
method that is in the same scope as a method-defined operation
region or an operation region under a module-level IF block.
This is rare, so the problem has not been seen before.
ACPICA BZ 826.
