Allow zero length strings during interpreter buffer-to-string
conversions. For example, during the ToDecimalString and
ToHexString operaters, as well as implicit conversions. Fiodor

Validates predefined ACPI objects that appear in the namespace,
at the time they are evaluated. The argument count and the type of
the returned object are validated. The purpose of this validation
is to detect problems with the BIOS-exposed predefined ACPI objects
before the results are returned to the ACPI-related drivers.

Predicate can be used for an implicit return value.
This change improves the implicit return mechanism to be more
compatible with the MS interpreter.

Below AML code from http://bugzilla.kernel.org/show_bug.cgi?id=10686
Store(0x07D6, OSYS)
Method (_CRT, 0, Serialized)
{
If (LLess (OSYS, 0x07D6))
{
If (LEqual (\_SB.TJ85, Zero))
{
Return (Add (0x0AAC, Multiply (TPC, 0x0A)))
}
Else
{
Return (Add (0x0AAC, Multiply (TP85, 0x0A)))
}
}
}
Previously _CRT returns 0x07D6, now it returns 0 (predicate value of LLess)

Fixed two possible memory leaks in the error exit paths of
acpi_ut_update_objerct_reference() and
acpi_ut_walk_package_tree()
These functions are similar in that they use a stack of state objects in
order to eliminate recursion. The stack must be fully deallocated
if an error occurs.

Previously aborted with error if too few arguments were passed to
a control method via the external ACPICA interface. Now issue a
warning instead and continue. Handles the case where the method
inadvertently declares too many arguments, but does not actually
use the extra ones. Applies mainly to the predefined methods.

ACPI_DB_ERROR and ACPI_DB_WARN were removed from ACPICA core.
So replace ACPI_DEBUG_PRINT((ACPI_DB_ERROR, ...) with printk(KERN_ERR PREFIX ...)
and ACPI_DEBUG_PRINT((ACPI_DB_WARN, ...) with printk(KERN_WARNING PREFIX ...)
We do not use ACPI_ERROR/ACPI_WARNING since they're not exported, see

Without this change, a table cannot be loaded again once it has
been loaded/unloaded one time. The current mechanism does not
unregister a table upon an unload. During a load, if the same
table is found, this no longer returns an exception.

Previously, dynamically loaded tables were simply mapped, but on some machines
this memory is corrupted after suspend. Now copy the table to a local buffer.
For OpRegion case, added checksum verify. Use the table length from the table header,
not the region length. For Buffer case, use the table length also.
