Byte swap was applied in the wrong order with testing for RLIM_INFINITY. On mips bigendian from an amd64 system this results in infinity being misinterpretted as 2^31-1. This is a serious bug because it causes setrlimit stack size to kill all child processes. This means (for example) that 'make' can run no children. The mechanism of failure: 1. parent sets stack size rlimit to 'infinity' 2. qemu screws this value up 3. child process fetches stack size as a large (but non-infinite) value 4. qemu tries to allocate stack before execution 5. stack allocation fails (too big) and child process dies Signed-off-by: Wesley W.
