I know you guys don't really care about them, but there might
be uses in out of tree drivers.

With the change what is output for %#p ?

I know I've used %#p in some code (possibly userspace) that need
to run under multiple OS because 0x%p generates 0x0x on one of the OS.
(We might have removed them because of the gcc warning though.)
