On mips platforms the second cacheflush parameter is the number of bytes in cache that needs to be flushed. When we are discarding translation we need to use this number instead of: ((ULong) ARG2) - ((ULong) ARG1) + 1ULL This patch also include syscall wrapper for __NR_sigaction on mips32. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13707
