Kees Cook 300a2b9c2b randomize_kstack: Improve entropy diffusion
[ Upstream commit 9c573cd313433f6c1f7236fe64b9b743500c1628 ]

The kstack_offset variable was really only ever using the low bits for
kernel stack offset entropy. Add a ror32() to increase bit diffusion.

Fixes: 39218ff4c6 ("stack: Optionally randomize kernel stack offset each syscall")
