[PATCH 0/1] MR8577: wow64cpu: In Unix calls, always return the status from the non-Wow dispatcher.

[Tim Clem (＠tclem)]

Even if WOW64_CPURESERVED_FLAG_RESET_STATE ends up being set.

---

Unix call equivalent of 419e4d69d6c3a4ea8b355f8b3fc211950eed0cdd. After 7ef95229913cf004d002459fe9e53307344479f2, a SIGUSR1 in the middle of a Unix call can set WOW64_CPURESERVED_FLAG_RESET_STATE. If that happens, the original eax from before the Unix call will be restored in syscall_32to64_return, stomping on the actual return from the Unix function.

Thanks to @gofman for help spotting this!
