Make the transition to protected mode more paranoid by having back-to-back near jump (to synchronize the 386/486 prefetch queue) and far jump (to set up the code segment.) While we're at it, zero as many registers as practical (for future expandability of the 32-bit entry interface) and enter 32-bit mode with a valid stack. Note that the 32-bit code cannot rely on this stack, or we'll break all other existing users of the 32-bit entrypoint, but it may make debugging hacks easier to write. Signed-off-by: H.
