x86: 32 bit: interrupt stub consistency with 64 bit
Don't generate interrupt stubs for interrupt vectors below FIRST_EXTERNAL_VECTOR, and make the table of interrupt vectors (interrupt[]) __initconst. Both of these changes both conserve memory and improve consistency with 64 bits. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
