unify arch/x86/kernel/tlb.c

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.
