    [PATCH] v850 kernel entry fixes and cleanup · 97f1c050
    Miles Bader authored
    1) Preserve the v850 system-call-number register when handling a signal;
       otherwise system calls will not be correctly restarted afterwards
    2) Correctly handle illegal insn exceptions, which need a special
       instruction to return (not reti), and save PC/PSW to a different place
    2) Remove some unnecessary register saving in the trap handler
    3) Consolidate various places that use the register save/restore macros
    4) Eliminate some unused compile-time configuration stuff
    5) A bit of whitespace and other syntactic cleanup
