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.[judith@osdl.org: powerpc build fix]

Currently acpiphp calls pci_enable_device() against all
hot-added bridges, but acpiphp does not call pci_disable_device()
against them in hot-remove. So ioapic hot-remove would fail.

Contrary to PCI bridge hot-add, we need to follow the sequence below
for PCI bridge hot-removal.(1) Stop devices (detach drivers, remove from the global list, etc.)
(2) Unbind ACPI node from the devices (remove the _PRT entries)
(3) Remove devices (remove from the device list, etc.)This patch fixes acpiphp driver to follow above sequence for P2P

This patch adds pci_stop_bus_device() which stops a PCI device (detach

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 stuffSigned-off-by: Alan Cox

Patch 4 implements error handlers for pcie_portdrv.
Signed-off-by: Zhang Yanmin
Signed-off-by: Greg Kroah-Hartman -
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.Signed-off-by: Zhang Yanmin

Introduce msi_ht_cap_enabled() to check the MSI capability in the
Hypertransport configuration space.
It is used in a generic quirk quirk_msi_ht_cap() to check whether
MSI is enabled on hypertransport chipset, and a nVidia specific quirk
quirk_nvidia_ck804_msi_ht_cap() where two 2 HT MSI mappings have to
be checked.
Both quirks set the PCI_BUS_FLAGS_NO_MSI bus flag when MSI is disabled.Signed-off-by: Brice Goglin

Export the PCI_BUS_FLAGS_NO_MSI flag of a PCI bus in the sysfs files
of its parent device and make it writable. Could be used to:
* disable MSI on a device which has not been blacklisted yet
* allow MSI when some setpci hacks enable MSI support (for instance
on the ServerWorks HT2000 chipset where the MSI HT cap is disabled
by default).
Architecture where some bus have no parent chipset cannot use this
strategy to change MSI support.If the chipset does not have a subordinate bus, its 'bus_msi' file
is empty.Also document and warn about the possible danger of changing the flag.

pci_enable_msi() and pci_enable_msix() use the same code to detect
whether MSI might be enabled on this device. Factorize this code in
pci_msi_supported(). And improve the documentation about the fact
that only the root chipset must support MSI, but it is hard to
find the root bus so we check all parent busses MSI flags.Signed-off-by: Brice Goglin

Move MSI quirks in CONFIG_PCI_MSI, document why the serverworks quirk

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.Cc: gregkh@suse.de

This provides a build and run-time option to turn on multhreaded probe
for all PCI drivers. It can cause bad problems on multi-processor
machines that take a while to find their root disks, and play havoc on
machines that don't use persistant device names for block or network
devices.But it can cause speedups on some machines, my tiny laptop's boot goes
up by 0.4 seconds, and my desktop boots up several seconds faster.Use at your own risk!!!

know success/failure.Convert the only driver that checked the return value of

Convert some framework code to handle the new PRETHAW message.
- IDE just treats it like a FREEZE.

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.
