Revision 9a40ac86152c9cffd3dca482a15ddf9a8c5716b3 authored by Khem Raj on 04 June 2010, 03:05:15 UTC, committed by Russell King on 08 June 2010, 18:42:18 UTC 
ARM: 6164/1: Add kto and kfrom to input operands list.
 
When functions incoming parameters are not in input operands list gcc
4.5 does not load the parameters into registers before calling this
function but the inline assembly assumes valid addresses inside this
function. This breaks the code because r0 and r1 are invalid when
execution enters v4wb_copy_user_page ()

Also the constant needs to be used as third input operand so account
for that as well.

Tested on qemu arm.
