MIPS: checksum: Split the 'copy_user' symbol
The 'copy_user' symbol can be used to copy from or to userland so we will use two different symbols for these operations. This makes no difference in the existing code, but when the core is operating in EVA mode, different instructions need to be used to read and write to userland address space. The old function has also been renamed to 'copy_kernel' to denote that it is suitable for copy data to and from kernel space. Signed-off-by: Markos Chandras <markos.chandras@imgtec.com>
