Hi Dan and Jason,

Bharata has been working on secure page management for kvmppc guests,
and one I thing I noticed is that he had to fake up a struct device
just so that it could be passed to the devm_memremap_pages
instrastructure for device private memory.

This series adds non-device managed versions of the
devm_request_free_mem_region and devm_memremap_pages functions for
his use case.
