Ralf Baechle 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().

never initialized been initialized anywhere, just saved to and
restored from signal frames so nonsense anyway.  As neat side effect
of being shared between all processors it was also abusable as a
nice covert channel between processes.

Ralf Baechle 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.

back.
