Kees Cook 300a2b9c2b randomize_kstack: Improve entropy diffusion ...

[ Upstream commit 9c573cd313 ]

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

Suggested-by: Arnd Bergmann <arnd@arndb.de>
Fixes: 39218ff4c6 ("stack: Optionally randomize kernel stack offset each syscall")
