Various mips64 and ppc64 qemu tests crash as follows
in v4.14.y and v4.17.y (the log is from ppc64).

I started to bisect, but abandoned it after finding commit 62d7ce7f40a9
("posix-timers: Fix nanosleep_copyout() for CONFIG_COMPAT_32BIT_TIME")
in both branches. Since there is no "config COMPAT_32BIT_TIME" in v4.14.y
or v4.17.y, some relevant code is commented out by the commit, which in
turn results in the crash.
