This patch causes a crash with qemu's mcimx6ul-evk emulation while running
imx_v6_v7_defconfig.

[ 19.976852] Run /sbin/init as init process
[ 20.044931] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004

There is nothing else useful in the log, unfortunately.

Reverting the following three patches fixes the problem.

74d06efb9c2f ARM: 8932/1: Add clock_gettime64 entry point
052e76a31b4a ARM: 8931/1: Add clock_getres entry point
20e2fc42312f ARM: 8930/1: Add support for generic vDSO
