I tried your two patches with:

A) a clean multi_v7_defconfig and no extra patches on:
* 4.13.2
* 4.13.3

B) a multi_v7_defconfig excluding CONFIG_DRM_TEGRA
(causes build errors):
* 4.14.0-rc1, no extra patches
* 4.14.0-rc2, no extra patches
* 4.14.0-rc1, with SMP patches [0]

All these kernels hung for me for the mentioned stress-ng tests
almost immediately.

I was also lucky to at least get a glimpse at a kernel crash
output during a chdir test once. Unfortunately still cut very early:

~~~
[   97.499390] Unhandled fault: external abort on non-linefetch (0x1008) at 0
