61 first appeared in the 2.6.36 release. Since then the kernel has had
62 code that reloads $v0 upon syscall restart and resumes right at the
63 SYSCALL instruction, so no special arrangement is needed anymore.
64
65 For backwards compatibility with existing kernel binaries we support
66 the old convention by choosing the instruction preceding SYSCALL
67 carefully. This also means we have to force a 32-bit encoding of the
68 microMIPS MOVE instruction if one is used. */
