[PATCH 0/4] unify arch/x86/kernel/tlb.c

[Jeremy Fitzhardinge]

This series converts tlb_32.c and _64.c to use smp_call_function_mask.  
Having done that, their underlying similarity is plainly revealed, and 
they can be easily unified.

The result is the removal of ~270 lines of code, most of which was a 
pair of open-coded versions of what smp_call_function_mask does anyway.  
The remaining code is much clearer as a result.

I've given these patches some mild testing, and nothing exploded.  I'm 
actually fairly confident in them, since all the complex subtle stuff is 
now in smp_call_function_mask, so if anything breaks, it's probably 
going to be in there.

And though I dare not touch it, Voyager could probably be converted to 
use this code fairly simply as well.
