    x86: remove pointless uaccess_32.h complexity · 5b09c3ed
    Linus Torvalds authored
    I'm looking at trying to possibly merge the 32-bit and 64-bit versions
    of the x86 uaccess.h implementation, but first this needs to be cleaned
    up.
    
    For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly
    the special cases for the constant size, and it's actually never
    relevant.  Every user except for one aren't actually using a constant
    size anyway, and the one user that uses it is better off just using
    __put_user() instead.
    
    So get rid of the unnecessary complexity.
    
    [ The same cleanup should likely happen to __copy_from_user_inatomic()
      as well, but that one has a lot more users that I need to take a look
      at first ]
