      [POWERPC] RTAS MSI implementation · 85f2bf9f
      由 Michael Ellerman 提交于 
      Implement MSI support via RTAS (RTAS = run-time firmware on pSeries
machines).  For now we assumes that if the required RTAS tokens for
MSI are present, then we want to use the RTAS MSI routines.

When RTAS is managing MSIs for us, it will/may enable MSI on devices that
support it by default. This is contrary to the Linux model where a device
is in LSI mode until the driver requests MSIs.

To remedy this we add a pci_irq_fixup call, which disables MSI if they've
been assigned by firmware and the device also supports LSI. Devices that
don't support LSI at all will be left as is, drivers are still expected
to call pci_enable_msi() before using the device.

At the moment there is no pci_irq_fixup on pSeries, so we can just set it
unconditionally. If other platforms use the RTAS MSI backend they'll need
to check that still holds.

      [POWERPC] Add powerpc PCI-E reset API implementation · 00c2ae35
      由 Brian King 提交于 
      Adds the pSeries platform implementation for a new PCI API
which can be used to issue various types of PCI-E reset,
including PCI-E warm reset and PCI-E hot reset. This is needed
for an ipr PCI-E adapter which does not properly implement BIST.
Running BIST on this adapter results in PCI-E errors. The only
reliable reset mechanism that exists on this hardware is PCI
Fundamental reset (warm reset).

      PCI: Cleanup the includes of <linux/pci.h> · 6473d160
      由 Jean Delvare 提交于 
      I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

      remove "struct subsystem" as it is no longer needed · 823bccfc
      由 Greg Kroah-Hartman 提交于 
      We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

      [POWERPC] pseries: Handle null iommu dma-window property correctly · 650f7b3b
      由 Linas Vepstas 提交于 
      Some versions of pSeries firmware fail to set up a
dma-window property for PCI slots that are unoccupied.
As a result, the loop searching for this propery, in
pci_dma_dev_setup_pSeriesLP(), can run to the end, resulting
in a NULL pointer dereference later in the routine. This
patch prevents the crash, and prints a warning message.

This is theoretically a rare error, as it occurs on what
is hopefully just beta levels of firmware. But just in case
this firmware escapes into the wild, this patch will avoid
the crash.
