The x86 architecture has quite a few different ways to jump into

kernel code.  Most of these entry points are registered in

arch/x86/kernel/traps.c and implemented in arch/x86/kernel/entry_64.S

and arch/x86/ia32/ia32entry.S.

for 64-bit, arch/x86/kernel/entry_32.S for 32-bit and finally

arch/x86/ia32/ia32entry.S which implements the 32-bit compatibility

syscall entry points and thus provides for 32-bit processes the

ability to execute syscalls when running on 64-bit kernels.



The IDT vector assignments are listed in arch/x86/include/irq_vectors.h.
