vprintf() is equivalent to vfprintf() to stdout so implement it as a simple
wrapper for the existing vfprintf(), allowing us to build kselftest.h.

Paul, feel free to directly queue this one for 6.5. If you prefer I
can as well queue it on my side and send it later, it's just that I
have exactly zero extra value on top of this one ;-)

Alternatively, if it would be more convenient for Mark to send this
up via kselftest:

It currently merges cleanly with the -rcu tree's dev branch, so this
should not be a problem.

Either way, please let me know, Mark!



I can take these through kselftest or can go through arm64
