an email from Ingo Molnar:

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
-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.
