Secure? No. Not at all.

It's actually very easy to fool it. Do something like this:

 - map the same physical page executably at one address, and writably
4kB above it (use shared memory, and map it twice).

 - in that page, do this:

      lea 1f,%edx
      movl $SYSCALL,%eax
      movl $-1,4096(%edx)
  1:
      int 0x80

and what happens is that the move that *overwrites* the int 0x80 will
not be noticed by the I$ coherency because it's at another address,
but by the time you read at $pc-2, you'll get -1, not "int 0x80"
