 * For vmklinux, the trick below doesn't work.  It works by raising a

 * pointing to a struct bug_frame.  However, pushq can only have a

 * 32-bit immediate, so we can't push the 64-address of __FILE__ into

 * it (this works on linux, because linux is loaded at -2Gb, and when

 * 'signed int filename' is cast to long it is sign-extended, the top

 * bits filled to 0xffff... and the address is correct.  Besides this,

 * the vmkernel ud2 exception handler doesn't know anything about

 * this.  So the long and the short of it is - we don't do any of this

 * arch specific BUG() stuff, and just fall back to the generic

 * panic()
