usercopy in PPC64

[Christophe LEROY]

Hi all powerpc64 experts,

While looking at the usercopy efficiency for PPC32, I noticed something 
which looks strange.

In asm/uaccess.h, raw_copy_from_user() and raw_copy_to_user() implements 
a fast path using get_user() and put_user() for copies of constant size < 8.

But INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER are only defined for 
PPC32, so PPC64 will call __copy_tofrom_user() even for small constant 
size copies. Is that wanted ?
