There exist systems which are known to do weird things if an SMI comes in right after a mode switch, and the safest way to deal with it is to always follow with a simple absolute far jump. In the 64-bit code we then to a register indirect near jump; follow that pattern for the 32-bit code. Signed-off-by: H.
