The page_unprotect() function is running everything locked. Before every potential exit path of the function mmap_unlock() gets called to make sure we don't leak the lock. However, the function calls tb_invalidate_phys_page() which again can exit a signal through longjmp, leaving our mmap_unlock() attempts in vain. Add a hint to tb_invalidate_phys_page() that we need to unlock before we can leave back into guest context, so that we don't leak the lock. This fixes 16-bit i386 wine programs running in linux-user for me. Signed-off-by: NAlexander Graf <agraf@suse.de> Signed-off-by: NRiku Voipio <riku.voipio@linaro.org>
