Dynamic nop selection breaks boot on Geode LX

[Daniel Drake]

Hi,

linux-next fails to boot on OLPC's XO-1 laptop based on Geode LX processor.

This is because of

commit f49aa448561fe9215f43405cac6f31eb86317792

    jump label: Make dynamic no-op selection available outside of ftrace

http://git.kernel.org/?p=linux/kernel/git/mingo/linux-2.6-x86.git;a=commitdiff;h=f49aa44

The Geode hangs inside the asm() statement inside arch_init_ideal_nop5.

Any thoughts?

I'm a bit out of my depth debugging assembly code, but will happily
take pointers and patches to help diagnose.

cheers
Daniel
