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.
The IDT vector assignments are listed in arch/x86/include/asm/irq_vectors.h.
Some of these entries are:
