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.
Tested kvmppc ultravisor patchset with migrate_vma changes and this
patchset. (Had to manually patch mm/memremap.c instead of kernel/memremap.c
though)
For the series,
