Log Message:
be sure to re-enable interrupts before calling trap() a second time
due to an AST.  the rule is that we must always have interrupts
enabled when acquiring kernel_lock, so that we can process blocking IPIs
from another CPU which is already holding kernel_lock.
reduce differences between the MP and non-MP versions of this file.
