x86, PPC and SPARC will randomize the application heap and library load addresses depending on the value of randomize_va_space. This patch set implements address space randomization for MIPS. Tested with a 64-bit kernel (OCTEON) and verified, for all three ABIs, that the result of 'cat /proc/self/maps' gives different values for [heap] and shared libraries with each invocation. The stack was already randomized and also gets a different value for each invocation. Someone may want to test it on a 32-bit kernel, but it should work there as well. I will reply with the two patches.
