Subject: [PATCH 0/5] devres: Add functions + migrate Xillybus driver

This patchset consists of new functions to the managed device resource
API, followed by patches for the Xillybus driver that now relies on these.

Rationale: While migrating the staging/xillybus driver to rely completely on
managed resources, some functionalities were missing, and hence added:

* devm_get_free_pages()
* devm_free_pages()
* dmam_map_single()
* dmam_unmap_single()
* pcim_map_single()
* pcim_unmap_single()

After applying these patches, the Xillybus driver uses all six functions,
and has been hardware tested on arm and x86_32. A compilation check went
cleanly on x86_64 as well.

Dependencies:
Patch #3 relies on patch #2 (quite obviously).
Patch #5 relies on all previous patches.

Thanks,
   Eli
