powerpc/eeh: Replace pr_warning() with pr_warn()

2014-08-05T05:41:34+00:00

pr_warn() is equal to pr_warning(), but the former is a bit more
formal according to commit fc62f2f ("kernel.h: add pr_warn for
symmetry to dev_warn, netdev_warn").

The patch replaces pr_warning() with pr_warn().

powerpc/eeh: Refactor EEH flag accessors

2014-08-05T05:41:21+00:00

There are multiple global EEH flags. Almost each flag has its own
accessor, which doesn't make sense. The patch refactors EEH flag
accessors so that they look unified:

  eeh_add_flag():   Add EEH flag
  eeh_clear_flag(): Clear EEH flag
  eeh_has_flag():   Check if one specific flag has been set
  eeh_enabled():    Check if EEH functionality has been enabled

powerpc/eeh: Remove reference to PCI device

2013-07-24T04:18:46+00:00

We will rely on pcibios_release_device() to remove the EEH cache
and unbind EEH device for the specific PCI device. So we shouldn't
hold the reference to the PCI device from EEH cache and EEH device.
Otherwise, pcibios_release_device() won't be called as we expected.
The patch removes the reference to the PCI device in EEH core.

Merge tag 'v3.10' into next

Merge 3.10 in order to get some of the last minute powerpc
changes, resolve conflicts and add additional fixes on top
of them.

powerpc/eeh: Avoid build warnings

2013-07-01T01:10:33+00:00

The patch is for avoiding following build warnings:

   The function .pnv_pci_ioda_fixup() references
   the function __init .eeh_init().
   This is often because .pnv_pci_ioda_fixup lacks a __init

   The function .pnv_pci_ioda_fixup() references
   the function __init .eeh_addr_cache_build().
   This is often because .pnv_pci_ioda_fixup lacks a __init

powerpc/eeh: Fix address catch for PowerNV

2013-07-01T01:10:32+00:00

On the PowerNV platform, the EEH address cache isn't built correctly
because we skipped the EEH devices without binding PE. The patch
fixes that.

powerpc/eeh: Move common part to kernel directory

2013-06-20T07:05:35+00:00

The patch moves the common part of EEH core into arch/powerpc/kernel
directory so that we needn't PPC_PSERIES while compiling POWERNV
platform:

        * Move the EEH common part into arch/powerpc/kernel
        * Move the functions for PCI hotplug from pSeries platform to
          arch/powerpc/kernel/pci-hotplug.c
        * Move CONFIG_EEH from arch/powerpc/platforms/pseries/Kconfig to
          arch/powerpc/platforms/Kconfig
        * Adjust makefile accordingly
