 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.

 Some of these entries are:
