Take it out of uaccess_32.h. Since it seems that no users
of the x86_64 exists, we simply pick the i386 version.

Merge versions of getuser from uaccess_32.h and uaccess_64.h into
uaccess.h. There is a part which is 64-bit only (for now), and for
that, we use a __get_user_8 macro.

Common parts of uaccess_32.h and uaccess_64.h
are put in uaccess.h. Bits in uaccess_32.h and
uaccess_64.h that come to this file are equal
except for comments and whitespaces differences.

Using explicit hexa (0xFFFFFFUL) introduces an unnecessary difference
between i386 and x86_64 because of the size of their long. Use -1UL instead.

Put the likely hint in access_ok. Just for
bisectability.

Our integration efforts broke a build with this function being used
with i386. Reason is "g" can put the operand in an imm32, which according
to The Book (tm), is invalid as the second operand.
This is actually a bug
in x86_64 too, since the x86_64 instruction set reference does not list
it as valid.
We probably didn't trigger this before due to the ammount of
registers available for 64-bit platforms. But that's just my guess.

For i386, __range_not_ok is a better name than __range_ok, since
it returns 0 when it is in fact okay. Other than that,
both versions does not need the word size specifiers, and we remove them.

This is consistent with i386 usage.

Instead of clobbering r8, clobber rbx, which is the i386 way.

There's really no reason to clobber r8 or pass the address in rcx.
We can safely use only two registers (which we already have to touch anyway)
to do the job.

Use the _ASM_EXTABLE macro from <asm/asm.h>, instead of open-coding
__ex_table entires in include/asm-x86/uaccess_64.h.
