Implemented support for the ACPI 3.0 Timer operator. This
ASL function implements a 64-bit timer with 100 nanosecond
granularity.

Defined a new OSL interface, acpi_os_get_timer. This
interface is used to implement the ACPI 3.0 Timer
operator. This allows the host OS to implement the timer
with the best clock available.  Also, it keeps the core
subsystem out of the clock handling business, since the
host OS (usually) performs this function.

Fixed an alignment issue on 64-bit platforms. The
hw_low_level_read/write() functions use a 64-bit address
which is part of the packed ACPI Generic Address
Structure. Since the structure is non-aligned, the
alignment macros are now used to extract the address to
a local variable before use.

Fixed a problem where the ToInteger operator assumed all
input strings were hexadecimal. The operator now handles
both decimal strings and hex strings (prefixed with "0x").

Fixed a problem where the string length in the string
object created as a result of the internal ConvertToString
procedure could be incorrect.  This potentially affected
all implicit conversions and also the ToDecimalString and
ToHexString operators.

Fixed two problems in the ToString operator. If the
length parameter was zero, an incorrect string object was
created and the value of the input length parameter was
inadvertently changed from zero to Ones.

Fixed a problem where the optional ResourceSource string
in the ExtendedIRQ resource macro was ignored.

Simplified the interfaces to the internal division
functions, reducing code size and complexity.

Added a new OSL interface, acpi_os_get_timer.  This
interface implements a 64-bit monotonic timer in 100
nanosecond units.

Implemented support for the ACPI 3.0 Timer operator.
This 64-bit timer utilizes the timer provided by the
acpi_os_get_timer interface.

Fixed a problem with the implementation of the LNot()
operator where "Ones" was not returned for the TRUE
case. Changed the code to return Ones instead of (!Arg)
which was usually 1. This change affects iASL constant
folding for this operator also.

Fixed a problem in acpi_ut_initialize_buffer where an
existing buffer was not initialized properly -- Now zero
the entire buffer in this case where the buffer already
exists.

Changed the interface to acpi_os_sleep from (UINT32
Seconds, UINT32 Milliseconds) to simply (ACPI_INTEGER
Milliseconds). This simplifies all related code
considerably. This requires changes/updates to all OS
interface layers (OSLs.)

Implemented a new external interface,
acpi_install_exception_handler, to allow a system exception
handler to be installed. This handler is invoked upon
any run-time exception that occurs during control method
execution.

Added support for the DSDT in acpi_tb_find_table. This
allows the DataTableRegion() operator to access the local
copy of the DSDT.

Implemented support for implicit object conversion in
the non-numeric logical operators (LEqual, LGreater,
LGreaterEqual, LLess, LLessEqual, and LNotEqual.) Any
combination of Integers/Strings/Buffers may now be used;
the second operand is implicitly converted on the fly to
match the type of the first operand.  For example:

LEqual (Source1, Source2)

Source1 and Source2 must each evaluate to an integer, a
string, or a buffer. The data type of Source1 dictates the
required type of Source2.  Source2 is implicitly converted
if necessary to match the type of Source1.

Updated and corrected the behavior of the string
conversion support.  The rules concerning conversion of
buffers to strings (according to the ACPI specification)
are as follows:

ToDecimalString - explicit byte-wise conversion of buffer
to string of decimal values (0-255) separated by commas.

ToHexString - explicit byte-wise conversion of buffer to
string of hex values (0-FF) separated by commas.

ToString - explicit byte-wise conversion of buffer to
string.  Byte-by-byte copy with no transform except NULL
terminated.  Any other implicit buffer-to-string conversion

byte-wise conversion of buffer to string of hex values
(0-FF) separated by spaces.

Fixed a problem in acpi_ns_get_pathname_length where the
returned length was one byte too short in the case of a
node in the root scope.  This could cause a fault during
debug output.

CONFIG_ACPI_BLACKLIST_YEAR=2001 for old behaviour

new cmdline options: "acpi_dbg_layer=",  "acpi_dbg_level="
and /proc/acpi/debug_layer, debug_level now describe levels

This will enable drivers to work around BIOS deficiencies,
while still allowing the drivers to be more picky with "acpi=strict"

These workarounds are disabled if "acpi=strict"

Designed and implemented support within the AML interpreter
for the so-called implicit return.  This support returns
the result of the last ASL operation within a control
method, in the absence of an explicit Return() operator.
A few machines depend on this behavior, even though it
is not explicitly supported by the ASL language.  It is
optional support that can be enabled at runtime via the
acpi_gbl_enable_interpreter_slack flag.

Removed support for the PCI_Config address space from the
internal low level hardware interfaces (acpi_hw_low_level_read
and acpi_hw_low_level_write).  This support was not used
internally, and would not work correctly anyway because
the PCI bus number and segment number were not supported.
There are separate interfaces for PCI configuration space
access because of the unique interface.

that filesystems are interested in can have their own properly typed

Patch from Marc Singer

The work already done to rectify the timer code initialization missed
a necessary change.  This patch adds a timer initialization function
to the LPD7A400 machine type.  It also makes a small correction to the
kernel configuration that is out of step with the machine specific
Kconfig.

Patch from Marc Singer

This patch aligns the lh7a40x port with the updated structure of IDE
drivers.  It also removes an unused FIQ handler.  This patch is made
in order to get the lh7a40x port to build.
