Please see the following Bugzilla entry for more details: http://bugzilla.kernel.org/show_bug.cgi?id=10038 This was tested using a Malta 4Kc board in both little-endian and big-endian modes. The unit test program is available from the URL above. Note that only the "o32"-style system calls have been added. This is due to the fact that I have no suitable equipment to test the other flavors of MIPS ABI.
