  ia64 work.
  
  Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
  This prevents userspace from the possibility to see what addresses are being used by kernel.
  
  Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
  able to read the address of its kernel stack.
  
  Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
  thread's combined register and memory stack. (RSE can write out as many as 16K.)
