Fix ia64_do_tlb_purge, its broken in too many ways
1. Call SET_PER_CPU_DATA before making any calls to GET_THIS_PADDR
to ensure that per-cpu data is set up correctly.
2. Use the per_cpu variable to derive CURRENT_STACK_OFFSET rather
than reading it from a kernel register. See 1) for explanation
of why.
3. In the VHPT pruning code, don't use r25 as ia64_jump_to_sal,
which branches to ia64_do_tlb_purge expects r25 to be preserved.
There seems no reason not to use r2 as per the other purges
done in ia64_do_tlb_purge. Furthermore use r16 and r18 instead
of r20 and r24 for consistency reasons.
4. Move __va_ul(vcpu_vhpt_maddr(v)) comment outside of
#if VHPT_ENABLED as it also applies to code further down that
