yes Ingo - it's ugly but I had not that many choises:

1) allocate/deallocate if failed inside same routine
2) deallocate in restore_IO_APIC_setup (which would be much more
ugly and obscure)
3) allocate and deallocate in completely separated routines - didn't
even tried :)

So I've stopped on (1) 'case it was less_changing_the_sources patch.
