Hi. This got through most of the merge tests, but running linux-user
tests failed:

/home/petmay01/linaro/qemu-for-merges/build/all-linux-static/i386-linux-user/qemu-i386
-L ./gnemul/qemu-i386 i386/ls -l dummyfile
qemu-i386: /home/petmay01/linaro/qemu-for-merges/translate-all.c:146:
tb_unlock: Assertion `have_tb_lock' failed.

Seems to assert the first time we call tb_unlock(). Here's a backtrace:
Program received signal SIGABRT, Aborted.
