# \[PATCH 11/20\] powerpc: Move definitions of secondary CPU spinloop to header file - From: Benjamin Herrenschmidt \ - Date: 2009-07-23 05:59:57 - List: linuxppc-dev - Page: https://ratatoskr.run/linuxppc-dev/2009/07/9454482 - Thread: https://ratatoskr.run/linuxppc-dev/2009/07/9454482/t.md ```text Those definitions are currently declared extern in the .c file where they are used, move them to a header file instead.
