[resend PATCH] MAINTAINERS: Clarify UIO vs UACCESS maintainer

[Dan Williams]

The UIO file mask in MAINTAINERS was incorrectly directing UACCESS
(include/linux/uio.h) patches to Greg.

Tag Al as the UACCESS maintainer as Ingo and others have explicitly
required his ack before taking architecture patches that touch
lib/iov_iter.c.

I got a bounce last time I tried to send this, hopefully the situation
has improved now.

Al, let me know if you want this entry. Alternatively we can just do the
UIO file mask fixup by itself.

Sure, no problem, except that UACCESS refers to different things.
I'd probably call it UIOVEC, if we want a name that does refer to the
same somewhere (*BSD).  If anything, it's generalization of copyin/copyout
for non-userland destinations/sources; uaccess answer to (subset of) the
same problem would be set_fs()/get_fs() and the fewer we have left of that,
the better...
