01d42abdf3 Using get_nasid() to find the console node will blow up nicely if 
called on a another node than the console node, so use the master_nasid
instead and in the unlikely case that one isn't initialized yet, fall
back to get_nasid().

b382fe8483 No point in checking cpu_has_tlb before we've computed the CPU options. 
So for now we just unconditionally set the option - Linux wouldn't
work without a TLB anyway.
