Indeed. You'll note I signed off on the original removal :)

But looking at it again today, I was concerned for a while that we might
have been a little overzealous in removing <asm/user.h> -- looking at
what was removed, I didn't immediately spot that all the instances of
<asm/user.h> were essentially the same, because the regs definitions
mess it up a bit, as do the types used. It looked like it might have
been one of the Linux-defined structures which is actually _reasonable_
to export to userspace via kernel headers.

... hm... actually, they're _not_ the same. SH, i386, x86_64 and m68k
have an extra FP state pointer after u_ar0 -- and m68k, Blackfin and
H8300 all have 'int reserved' before u_ar0. The SPARC version is fairly
different, too.
