Hi everybody and happy new year,

I wondered what is the goal of tb_lock in cpu-exec.c.

According to the exec-all.h it's to protect tbs and page table but why do we
have to cover the whole cpu_exec function?

I'm asking this because we planned to reuse tb_lock to protect every 
access to
tb_ctx by replacing spinlock by QemuMutex.

Anybody has a clue?

Thanks,
Fred
