[Qemu-devel] [PULL v2 5/6] linux-user: fix the breakpoint inheritance in spawned threads

[riku . voipio]

From: Thierry Bultel <address@hidden>

When a thread is spawned, cpu_copy re-initializes
the bp & wp lists of current thread, instead of the ones
of the new thread.
The effect is that breakpoints are no longer hit.
