There are several duplicate definitions in cciss_cmd.h and cciss_ioctl.h.
Consolidate these into the new cciss_defs.h file. This patch doesn't change
the definitions exposed under include/linux, so userspace apps shouldn't
be affected.

Some cleanup before the header file split-out so we don't propagate this style
into new files.

Introduce kernel parameter acpi_sleep=sci_force_enable
some laptop requires SCI_EN being set directly on resume,
or else they hung somewhere in the resume code path.
We already have a blacklist for these laptops but we still need
this option, especially when debugging some suspend/resume problems,
in case there are systems that need this workaround and are not yet
in the blacklist.

AML code always sends notifications to ACPI video device,
even if we disable the ACPI backlight control by using
boot option "acpi_backlight=vendor".
In this case we should not print any warning message.

Allow the user to choose through Kconfig if the Console Audio Control
interface (aka "volume subdriver") should be available or not.
This not only saves some memory, but also allows the thinkpad-acpi
driver to be built-in even if ALSA is modular when the console audio
control interface is not wanted.
This change fixes a build problem that is causing some annoyances, in
a way that doesn't disable the entire driver on kernels without ALSA
support.

If we cannot create the ALSA mixer, it is a good reason to fail to
load the volume subdriver, and not to fail to load the entire module.
While at it, add more debugging messages, as the error paths are being
used a lot more than I'd expect, and it is failing to set up the ALSA
mixer on a number of ThinkPads.

We don't want to be the first soundcard. We don't want to shift other
soundcards out of the way either, even if they load much later.
Ask ALSA to (by default) load us in one of the last three slots. This
can be overriden at will using the "index" parameter.

It would appear that in BIOS's with nVidia hooks, the GUID
05901221-D566-11D1-B2F0-00A0C9062910 is duplicated. For now, the simplest
solution is to just ignore any duplicate GUIDs. These particular hooks are not
currently supported/ used in the kernel, so whoever does that can figure out
what the 'right' solution should be (if there's a better one).

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.
The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.

Today's -tip failed to build because commit
9e368fa011d4e0aa050db348d69514900520e40b ("ipmi: add PNP discovery (ACPI
namespace via PNPACPI)") from today's upstream kernel causes the following
build failure on x86, for CONFIG_ACPI=n && CONFIG_IPMI_SI=y:
drivers/char/ipmi/ipmi_si_intf.c:3208: error: 'ipmi_pnp_driver' undeclared (first use in this function)
drivers/char/ipmi/ipmi_si_intf.c:3208: error: (Each undeclared identifier is reported only once
drivers/char/ipmi/ipmi_si_intf.c:3208: error: for each function it appears in.)
drivers/char/ipmi/ipmi_si_intf.c:3334: error: 'ipmi_pnp_driver' undeclared (first use in this function)
The reason is that the ipmi_pnp_driver depends on ACPI facilities and is only
made available under ACPI - while the registration and unregistration is made
dependent on CONFIG_PNP:
#ifdef CONFIG_PNP
pnp_register_driver(&ipmi_pnp_driver);
#endif
The solution is to only register this driver under ACPI. (Also, the CONFIG_PNP
dependency is not needed because pnp_register_driver() is stubbed out in the
!CONFIG_PNP case.)

When continuing a pq calculation the driver needs 3 extra sources. The
driver can perform a 3 source calculation with a single descriptor, but
needs an extended descriptor to process up to 8 sources in one
operation. However, in the p-disabled case only one extra source is
needed. When continuing a p-disabled operation there are occasions
(i.e. 0 < src_cnt % 8 < 3) where the tail operation does not need an
extended descriptor. Properly account for this fact otherwise invalid
'dmacount' values will be written to hardware usually causing the
channel to halt with 'invalid descriptor' errors.

memset of 0 is not needed after kzalloc
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x;
statement S;
@@
x = kzalloc(...);
if (x == NULL) S
... when != x
-memset(x,0,...);// </smpl>

The SH DMA driver wrongly assigns negative cookies to transfer descriptors,
also, its chaining of partial descriptors is broken. The latter problem is
usually invisible, because maximum transfer size per chunk is 16M, but if you
artificially set this limit lower, the driver fails. Since cookies are also
used in chunk management, both these problems are fixed in one patch. As side
effects a possible memory leak, when descriptors are prepared, but not
submitted, and multiple races have also been fixed.

The cardbus code creates PCI devices without ever going through the
necessary fixup bits and pieces that normal PCI devices go through.
There's in fact a commented out call to pcibios_fixup_bus() in there,
it's commented because ... it doesn't work.
I could make pcibios_fixup_bus() do the right thing on powerpc easily
but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus
for which a weak empty implementation is provided by the PCI core.
This fixes cardbus on powerbooks and probably all other PowerPC
platforms which was broken completely for ever on some platforms and
since 2.6.31 on others such as PowerBooks when we made the DMA ops
mandatory (since those are setup by the fixups).

Add a new type of quirk for resetting devices at pci_dev_reset time.
This is necessary to handle device with nonstandard reset procedures,
especially useful for guest drivers.

Prior to this patch, if pci_read_config_byte(dev, PCI_CACHE_LINE_SIZE, ...)
returns 0 for all dev, pci_cache_line_size ends up set to zero
(instead of pci_dfl_cache_line_size).
This patch ensures the pci_cache_line_size = pci_dfl_cache_line_size
setting in the above scenario.
This happens in case of a kvm-88 guest (where, consequently, the rtl8139
NIC failed to initialize).

Having read the PM part of the PCIe 2.0 specification more carefully
I think that it was a mistake to restrict the wake-up enable
propagation to non-PCIe devices, because if we do not request
control of the root ports' PME registers via OSC, PCIe PME is
supposed to be handled by the platform, just like the non-PCIe PME.
Even if we do that, the wake-up propagation is done to allow the
devices to wake up the system from sleep states which involves the
platform anyway, so it won't hurt.
