In kernel 2.5.6, PPP deflate isn't compiled correctly if CONFIG_SMP is off: the macros local_bh_enable() and local_bh_disable() aren't expanded and instead turn into references to undefined functions. The problem is that <linux/smp_lock.h> is insufficient in UP configs. The patch below adds an #include <linux/interrupt.h> which works around this. I'm not sure about <linux/smp_lock.h>: it really doesn't look appropriate for the locking primitives being used in ppp_deflate.c. /Mikael --- linux-2.5.6/drivers/net/ppp_deflate.c.~1~ Sat Mar 9 12:53:13 2002 +++ linux-2.5.6/drivers/net/ppp_deflate.c Sun Mar 10 14:32:04 2002 @@ -35,6 +35,7 @@ #include <linux/slab.h> #include <linux/vmalloc.h> #include <linux/init.h> +#include <linux/interrupt.h> #include <linux/smp_lock.h> #include <linux/ppp_defs.h> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
