dd159eeca9 [PATCH] genirq: msi: make the msi boolean tests return either 0 or 1
This allows the output of the msi tests to be stored directly in a bit field.
If you don't do this a value greater than one will be truncated and become 0.
Changing true to false with bizare consequences.

7bd007e480 [PATCH] genirq: msi: simplify msi enable and disable
The problem.  Because the disable routines leave the msi interrupts in all
sorts of half enabled states the enable routines become impossible to
implement correctly, and almost impossible to understand.

Simplifing this allows me to simply kill the buggy reroute_msix_table, and
generally makes the code more maintainable.

The cause of this problem might be an wrong assumption that the 'start'
member of resource structure for ioapic device has non-zero value if the
resources are assigned by firmware.  The 'start' member of ioapic device
seems not to be set even though the resources were actually assigned to
ioapic devices by firmware.

236561e5df [PATCH] PCI quirks update
This fixes two things

Firstly someone mistakenly used "errata" for the singular.  This causes
Dave Woodhouse to emit diagnostics whenever the string is read, and so
should be fixed.

Secondly the AMD AGP tunnel has an erratum which causes hangs if you try
and do direct PCI to AGP transfers in some cases.  We have a flag for
PCI/PCI failures but we need a different flag for this really as in this
case we don't want to stop PCI/PCI transfers using things like IOAT and the
new RAID offload work.

I'll post some updates to make proper use of the PCIAGP flag in the
media/video drivers to Mauro.

8e18e2941c [PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private
The following patches reduce the size of the VFS inode structure by 28 bytes
on a UP x86.  (It would be more on an x86_64 system).  This is a 10% reduction
in the inode size on a UP kernel that is configured in a production mode
(i.e., with no spinlock or other debugging functions enabled; if you want to
save memory taken up by in-core inodes, the first thing you should do is
disable the debugging options; they are responsible for a huge amount of bloat
in the VFS inode structure).

This patch:

The filesystem or device-specific pointer in the inode is inside a union,
which is pretty pointless given that all 30+ users of this field have been
using the void pointer.  Get rid of the union and rename it to i_private, with
a comment to explain who is allowed to use the void pointer.  This is just a
cleanup, but it allows us to reuse the union 'u' for something something where
the union will actually be used.

50b0075520 PCI: Multiprobe sanitizer
There are numerous drivers that can use multithreaded probing but having
some kind of global flag as the way to control this makes migration to
threaded probing hard and since it enables it everywhere and is almost
as likely to cause serious pain as holding a clog dance in a minefield.

If we have a pci_driver multithread_probe flag to inherit you can turn
it on for one driver at a time.

From playing so far however I think we need a different model at the
device layer which serializes until the called probe function says "ok
you can start another one now". That would need some kind of flag and
semaphore plus a helper function.

Anyway in the absence of that this is a starting point to usefully play
with this stuff

6c2b374d74 PCI-Express AER implemetation: AER core and aerdriver
Patch 3 implements the core part of PCI-Express AER and aerdrv
port service driver.

When a root port service device is probed, the aerdrv will call
request_irq to register irq handler for AER error interrupt.

When a device sends an PCI-Express error message to the root port,
the root port will trigger an interrupt, by either MSI or IO-APIC,
then kernel would run the irq handler. The handler collects root
error status register and schedules a work. The work will call
the core part to process the error based on its type
(Correctable/non-fatal/fatal).

As for Correctable errors, the patch chooses to just clear the correctable
error status register of the device.

As for the non-fatal error, the patch follows generic PCI error handler
rules to call the error callback functions of the endpoint's driver. If
the device is a bridge, the patch chooses to broadcast the error to
downstream devices.

As for the fatal error, the patch resets the pci-express link and
follows generic PCI error handler rules to call the error callback
functions of the endpoint's driver. If the device is a bridge, the patch
chooses to broadcast the error to downstream devices.

* allow MSI when some setpci hacks enable MSI support (for instance

Architecture where some bus have no parent chipset cannot use this

0637a70a5d [PATCH] x86: Allow disabling early pci scans with pci=noearly or disallowing conf1
Some buggy systems can machine check when config space accesses
happen for some non existent devices.  i386/x86-64 do some early
device scans that might trigger this. Allow pci=noearly to disable
this. Also when type 1 is disabling also don't do any early
accesses which are always type1.

This moves the pci= configuration parsing to be a early parameter.
I don't think this can break anything because it only changes
a single global that is only used by PCI.

1ae4f9ba84 USB: Add VIA quirk fixup for VT8235 usb2
Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235
southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after
no-IRQ?" error and the device is unusable.

I belive this could also be a fix for Bugzilla Bug 5835.

cc702c2c5e [PATCH] CPCI hotplug: fix resource assignment
Here is a patch against the CPCI hotplug core to fix up PCI resource
assignment such that things will actually work when a hot inserted
device is enabled.  I mentioned this patch to you way back in April at
ELC, but am only now out from under things enough to clean it up and
submit it.  I've basically cribbed the corresponding code from
shpchp_pci.c, so there are no big surprises.  If it's still possible, I
wouldn't mind this going into 2.6.18, but it wouldn't be the end of the
world if it went into 2.6.19.

65ae4dddbb [PATCH] PCI: fix ICH6 quirks
- add the ICH6(R) LPC to the ICH6 ACPI quirks.  currently only the ICH6-M
  is handled.  [ PCI_DEVICE_ID_INTEL_ICH6_1 is the ICH6-M LPC, ICH6_0 is
  the ICH6(R) ]

- remove the wrong quirk calling asus_hides_smbus_lpc() for ICH6.  the
  register modified in asus_hides_smbus_lpc() has a different meaning in
  ICH6.

b5240b32b9 ACPIPHP: allow acpiphp to build without ACPI_DOCK
Change the build options for acpiphp so that it may build without being
dependent on the ACPI_DOCK option, but yet does not allow the option of
acpiphp being built-in when dock is built as a module.
This does not change the previous patch for ACPI_IBM_DOCK Kconfig.

For the following matrix of config options, I built an i386 kernel.

Dock		acpiphp		should it build?	confirmed
y		y		y			y
y		n		y			y
y		m		y			y
m		y		no - acpiphp should	acpiphp was 
				     convert to m	converted to m
m		n		y			y
m		m		y			y
n		y		y			y
n		n		y			y
n		m		y			y
