__user removed from mtd-abi.h

[Ricard Wanderlof]

Hi,

I noticed that

#ifndef __KERNEL__
#define __user
#endif

has been removed from mtd-abi.h . I appreciate the reason, but I'm not 
sure how to include this file in userspace now and get it to compile 
properly.

The commitlog from dmwm2 says 'Now that we have headers_install, we don't 
need this crap.'. Makes sense, but where is __user supposed to be defined 
now - it is used as an identifier further down in the file, and userspace 
programs that include mtd-abi.h therefore break during compilation. 
mtd-abi.h doesn't appear to simply be a userspace version of a kernel 
include file.

Is the above fix in fact broken for this particular file or should be 
done in another way? I've had a look at the headers_install target in the 
top level kernel makefile as well as the scripts/unifdef.c program, but I 
seem to be going in circles. Could someone please enlighten me?

(As a side note, I've noticed that uClibc's include/features.h defines 
__user to cope with such issues, but glibc's doesn't. So it might not be 
appearant unless userspace code is built with glibc).
