ACPI: Don't print internal BIOS names of wakeup devices

Internal BIOS names like these should be exposed
to the user as little as possible:

ACPI wakeup devices: C069 C0CE C1D1 C0DE C1D4

Eventually, the "wakeup" property of a device should be exported via the
device tree, not by a printk of an internal BIOS name. For the hard-core,
these are still available in /proc/acpi/wakeup_devices, just not
printed to dmesg.

HPET: fix ACPI memory range length handling

ACPI address space descriptors contain _MIN, _MAX, and _LEN. _MIN and
_MAX
are the bounds within which the region can be moved (this is clarified in
Table 6-38 of the ACPI 3.0 spec). We should use _LEN to determine the
size
of the region, not _MAX - _MIN + 1.

ACPI: fix sonypi ACPI driver registration to unregister on failure

Remove the assumption that acpi_bus_register_driver() returns the number
of
devices claimed. Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).

This also fixes a bug: if sonypi_acpi_driver was registered but found no
devices, sonypi_exit() did not unregister it.

ACPI: update asus_acpi driver registration to unload on failure

Remove the assumption that acpi_bus_register_driver() returns the number
of
devices claimed. Returning the count is unreliable because devices may be
hot-plugged in the future (admittedly not applicable for this driver).

Since the hardware for this driver is not hot-pluggable, determine whether
the
hardware is present by noticing calls to the .add() method. It would be
better to probe the ACPI namespace for the ASUS HIDs, and load the driver
only
when we find one, but ACPI doesn't support that yet.

I don't have an ASUS laptop to test on, but on my HP dl360, it does report
the
appropriate error when attempting to load the module:

$ sudo insmod drivers/acpi/asus_acpi.ko
insmod: error inserting 'drivers/acpi/asus_acpi.ko': -1 No such device

ACPI: make acpi_bus_register_driver() return success/failure, not device
count

acpi_bus_register_driver() should not return the number of devices
claimed.
We're not asking to find devices, we're making a driver available to
devices,
including hot-pluggable devices that may appear in the future.

I audited all callers of acpi_bus_register_driver(), and except
asus_acpi.c
and sonypi.c (fixed in previous patches), all either ignore the return
value
or test only for failure (<0).

ACPI: request correct fixed hardware resource type (MMIO vs I/O port)

ACPI supports fixed hardware (PM_TMR, GPE blocks, etc) in either I/O port
or MMIO space, but used to always request the regions from I/O space
because it didn't check the address_space_id.

Sample ACPI fixed hardware in MMIO space (HP rx2600), was incorrectly
reported in /proc/ioports, now reported in /proc/iomem:

ff5c1004-ff5c1007 : PM_TMR
ff5c1008-ff5c100b : PM1a_EVT_BLK

PNPACPI: fix non-memory address space descriptor handling

Fix resource_type handling for QWORD, DWORD, and WORD Address Space
Descriptors. Previously we ignored the resource_type, so I/O ports and
bus
number ranges were incorrectly parsed as memory ranges.

Sample PCI root bridge resources from HP rx2600 before this patch:

# cat /sys/bus/pnp/devices/00:02/resources
state = active
mem 0x0-0x1f
mem 0x0-0x3af
mem 0x3e0-0x1fff
mem 0x80000000-0x8fffffff

With this patch:

# cat /sys/bus/pnp/devices/00:02/resources
state = active
io 0x0-0x3af
io 0x3e0-0x1fff
mem 0x80000000-0x8fffffff
mem 0x80004000000-0x80103fffffe

Changes:
0x0-0x1f PCI bus number range was incorrectly reported as memory, now
not reported at all
0x0-0x3af I/O port range was incorrectly reported as memory
0x3e0-0x1fff I/O port range was incorrectly reported as memory
0x80004000000-0x80103fffffe memory range wasn't reported at all
because
we only support PNP_MAX_MEM (4) memory resources

ACPI: ACPICA 20060310

Tagged all external interfaces to the subsystem with the
new ACPI_EXPORT_SYMBOL macro. This macro can be defined
as necessary to assist kernel integration. For Linux,
the macro resolves to the EXPORT_SYMBOL macro. The default
definition is NULL.

Added the ACPI_THREAD_ID type for the return value from
acpi_os_get_thread_id(). This allows the host to define this
as necessary to simplify kernel integration. The default
definition is ACPI_NATIVE_UINT.

Valery Podrezov fixed two interpreter problems related
to error processing, the deletion of objects, and placing
invalid pointers onto the internal operator result stack.
http://bugzilla.kernel.org/show_bug.cgi?id=6028

Increased the reference count threshold where a warning is
emitted for large reference counts in order to eliminate
unnecessary warnings on systems with large namespaces
(especially 64-bit.) Increased the value from 0x400
to 0x800.

Due to universal disagreement as to the meaning of the
'c' in the calloc() function, the ACPI_MEM_CALLOCATE
macro has been renamed to ACPI_ALLOCATE_ZEROED so that the
purpose of the interface is 'clear'. ACPI_MEM_ALLOCATE and
ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and ACPI_FREE.

ACPI: ACPICA 20060217

Implemented a change to the IndexField support to match
the behavior of the Microsoft AML interpreter. The value
written to the Index register is now a byte offset,
no longer an index based upon the width of the Data
register. This should fix IndexField problems seen on
some machines where the Data register is not exactly one
byte wide. The ACPI specification will be clarified on
this point.

Fixed a problem where several resource descriptor
types could overrun the internal descriptor buffer due
to size miscalculation: VendorShort, VendorLong, and
Interrupt. This was noticed on IA64 machines, but could
affect all platforms.

Fixed a problem where individual resource descriptors were
misaligned within the internal buffer, causing alignment
faults on IA64 platforms.

[ACPI] document cmdline acpi_os_name=

This can sometimes be used to work around broken BIOS.
Use "Microsoft Windows" to take the same path
through the BIOS as Windows98 would.

The default is "Microsoft Windows NT", which
is what NT and later versions of Windows use,
and is the most tested path through most BIOS.

Set it to anything else, including "Linux", at your
own risk, as it seems that virtually no BIOS
has been tested with anything but the two options above.

Note that this uses the legacy _OS interface, so
we don't expect this to ever change.
