From
Subjectmemcpy_tofs alignment question
Date
I am working on a driver for a mpeg encoder.  The encoder is on the
PCI bus. It supports only dword target-mode transfers.

Can I safely use memcpy_tofs for this? I don't know intel assembly,
so I can't tell whether the definition of _generic_memcpy_tofs in
segment.h will restrict itself to long word transfers if I ask for a
multiple of 4-byte and give it an aligned starting address.
