OpenBSD/sgi on octane2 - curprocpaddrをcurcpu()->ci_curprocpaddrへ移動(解決篇)
OpenBSD/sgi on octane2 - curprocpaddrをcurcpu()->ci_curprocpaddrへ移動 - かーねる・う゛いえむにっきの解決篇。
この間うまく動かなかったコードでは、一度GET_CPU_INFO(reg0, reg1)したら同じ関数ではもう一度取得しなおす事はせずreg0へ参照を行うだけで済ませていた。
が、特に関数呼び出しが行われた時にレジスタ破壊が起きている可能性が強いので、取り合えず毎回GET_CPU_INFO()しまくるように書き換えた。
