Tong Tiangen 8bb0ab3ae7 riscv/vdso: make arch_setup_additional_pages wait for mmap_sem for write killable ... riscv architectures relying on mmap_sem for write in their arch_setup_additional_pages. If the waiting task gets killed by the oom killer it would block oom_reaper from asynchronous address space reclaim and reduce the chances of timely OOM resolving. Wait for the lock in the killable mode and return with EINTR if the task got killed while waiting.
