[PATCH v2 0/5] PCI: Convert pci_resource_to_user() to a weak function

[PATCH v2 0/5] PCI: Convert pci_resource_to_user() to a weak function

[Denis Efremov]

Architectures currently define HAVE_ARCH_PCI_RESOURCE_TO_USER if they want
to provide their own pci_resource_to_user() implementation. This could be
simplified if we make the generic version a weak function. Thus,
architecture specific versions will automatically override the generic one.

Changes in v2:
1. Removed __weak from pci_resource_to_user() declaration
2. Fixed typo s/spark/sparc/g

[Denis Efremov]

The patch turns pci_resource_to_user() to a weak function. Thus,
architecture-specific versions will automatically override the generic
one. This allows to remove the HAVE_ARCH_PCI_RESOURCE_TO_USER macro and
avoid the conditional compilation for this single function.

Thanks, I added Paul's ack, squashed into a single patch since I think
it's easier to see what's going on then, and applied to pci/misc for
v4.5.
