Hi!
commit ed51862f2f57cbce6fed2d4278cfe70a490899fd upstream.
We will introduce the first architecture specific compat vm ioctl in the next patch. Add all necessary boilerplate to allow architectures to override compat vm ioctls when necessary.
AFAICT this introduces hooks, but they are not used at least in 5.10.
We should not need this...?
Best regards, Pavel
