You are increasing the size of encode_state beyond the size of a page
for no real reason/advantage. Please use a different approach where
Misc param buffers are maintained with a minimal set of members.
Mapping from VA misc buffer types to internal VA driver defs is a more
appropriate thing, for almost free: you just need to convert the buf
type once while parsing/accumulating the misc buffers through
vaRenderPicture() implementation. Next, misc buffers are accessed by
VA intel driver buf types instead.

i.e. this means another preparatory patch before this one.

Thanks,
Gwenole.
