/*
* Macros for interrupt entry, call to handler, and exit.
*
* XXX
* The interrupt frame is set up to look like a trap frame. This may be a
* waste. The only handler which needs a frame is the clock handler, and it
* only needs a few bits. Xdoreti() needs a trap frame for handling ASTs, but
* it could easily convert the frame on demand.
*
* The direct costs of setting up a trap frame are two pushq's (error code and
* trap number), an addl to get rid of these, and pushing and popping the
* callee-saved registers %esi, %edi, %ebx, and %ebp twice.
*
* If the interrupt frame is made more flexible, INTR can push %eax first and
* decide the ipending case with less overhead, e.g., by avoiding loading the
* segment registers.
*
