This is really bad, GCC isn't inlining anything.

So the deepest IRQ handler path eats up ~1152 bytes of stack space and
that's before we call into the scsi layer to indicate command
completion.

With gcc-4.0.x most of the IRQ path gets inlined even with the -Os we
are giving to GCC now.

What gcc version are you using again?  I'll try to reproduce here and
try to add some inline directives to try and cure this.

Thanks.
