Message-Id: <1281127422-15689-2-git-send-email-jason.wessel@windriver.com> Date: Fri, 6 Aug 2010 15:43:42 -0500 From: Jason Wessel <jason.wessel@...driver.com> To: torvalds@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, kgdb-bugreport@...ts.sourceforge.net, Jesse Barnes <jbarnes@...tuousgeek.org>, Jason Wessel <jason.wessel@...driver.com> Subject: [PATCH 1/1] console: Fix compilation regression A regression of building without CONFIG_HW_CONSOLE was introduced with commit b45cfba4e9005d64d419718e7ff7f7cab44c1994 (vt,console,kdb: implement atomic console enter/leave functions). ERROR: "con_debug_enter" [drivers/serial/kgdboc.ko] undefined! ERROR: "vc_cons" [drivers/serial/kgdboc.ko] undefined! ERROR: "fg_console" [drivers/serial/kgdboc.ko] undefined! ERROR: "con_debug_leave" [drivers/serial/kgdboc.ko] undefined! When there is no HW console the con_debug_enter and con_debug_leave functions should have no code.
