Subject: cpu-exec: Also reload CPUClass *cc after longjmp return in cpu_exec()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Local variable CPUClass *cc needs to be reloaded after return from longjmp,
too.  (This fixes a mips-softmmu crash observed on FreeBSD when QEMU is
built with clang.)
