- * O32 function call dispatcher, for interfacing 32-bit ROM routines.
- *
- * The standard 64 (N32) calling sequence is supported, with a0
- * holding a function pointer, a1-a7 -- its first seven arguments
- * and the stack -- remaining ones (up to O32_ARGC, including a1-a7).
- * Static registers, gp and fp are preserved, v0 holds a result.
- * This code relies on the called o32 function for sp and ra
- * restoration and thus both this dispatcher and the current stack
- * have to be placed in a KSEGx (or KUSEG) address space.  Any
- * pointers passed have to point to addresses within one of these
- * spaces as well.
