From ac85227f7637cfb0d811519b8253c454d0d0a159 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Thu, 12 Dec 2013 16:21:00 +0000 Subject: 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.
