[PATCH rdma-core 02/20] rxe: Move rxe to exclusively use the kernel uapi headers

[Jason Gunthorpe <jgg@xxxxxxxx>]

From: Jason Gunthorpe <jgg@xxxxxxxxxxxx>

Useing the driver support macros we can now directly create the
required driver structs automatically.

Only mmap_info needed to be renamed, using this script:

$ sed -i \
 -e 's/struct[ \t]mmap_info\([ \t,]\)/struct mminfo\1/g'\
 `git ls-files`
