net/built-in.o(.init.text+0x1b2): In function `flow_cache_init':
: undefined reference to `register_cpu_notifier'
make: *** [.tmp_vmlinux1] Error 1

Added to net/core/flow.c

#include <linux/cpu.h>

Compiled OK, but netfilter not tested.

Powered by linux-2.5.71, compiled with gcc-2.95-3 because it's rock solid

My current linux related activities in rough order of priority:
- Testing of Swsusp for 2.4
- Learning 2.5 kernel debugging with kgdb - it's in the -mm tree
- Studying 2.5 serial and ide drivers, ACPI, S3

The 2.5 kernel could use your usage. More info on setting up 2.5 kernel at
