I have problems linking Linux SPARC32 when SMP is enabled:
LD vmlinux
SYSMAP System.map
SYSMAP .tmp_System.map
BTFIX arch/sparc/boot/btfix.S
AS arch/sparc/boot/btfix.o
LD arch/sparc/boot/image
net/built-in.o: In function `net_rps_action_and_irq_enable':
/home/daniel/linux/linux/linux-2.6/net/core/dev.c:3337: undefined
reference to `__smp_call_function_single'
make[1]: *** [arch/sparc/boot/image] Error 1
make: *** [zImage] Error 2
It's a missing dependency in the networking code, I'll fix this
in the net-2.6 tree as follows:
--------------------
net: RPS needs to depend upon USE_GENERIC_SMP_HELPERS
You cannot invoke __smp_call_function_single() unless the
architecture sets this symbol.

That resolved the problem nicely.
Thank you very much,
