rS297399: Type of the interrupt handlers on x86 cannot be expressed in C.
Summary

Types for the x86 interrupt handler entry points cannot be expressed in C. For i386, the existing type is some approximation, lacking __stdcall attribute and still being wrong for the return type. For amd64, it cannot be even approximated.

Instead, use void (*)(void) which equally serves the purpose, is simpler and allows to unify i386 and amd64.

Fine with me. The things can't be written directly in C anyway so trying to have a fancy prototype is rather pointless.
