Committed with a slightly different name `debug.acpi.avoid.paths' .

It translates to something as below. I don't know what it does though,
as I have zero knowledge of the SMI register.

  #define SMIC 0xB2
  #define SMID 0xB3
  int val;
  /* acquire mutex for this operation here */
  outb(SMID, 0x04);
  outb(SMIC, 0x95);
  while (inb(SMIC) != 0)
	  ;
  val = inb(SMID);
  /* release mutex for this operation here */
