This adds a lock to avoid multiple exclusive access at the same time in case of

Hi Peter,
All the same comments I had on this patch earlier still apply:
* I think adding mutex handling code to all the target-*
frontends rather than providing facilities in common
code for them to use is the wrong approach
Ok we will fix that.
* You will fail to unlock the mutex if the ldrex or strex
takes a data abort
* This is making no attempt to learn from or unify with
the existing attempts at handling exclusives in linux-user.
When we've done this work we should have a single
mechanism for handling exclusives in a multithreaded
host environment which is used by both softmmu and useronly
configs
Can you point me to the existing attempts in linux-user?
Thanks,
Fred
