Enable page allocator freelist randomization
https://outflux.net/blog/archives/2019/07/17/security-things-in-linux-v5-2/
CONFIG_SHUFFLE_PAGE_ALLOCATOR
is enabled in the Debian kernel but this needs to be enabled at boot time with page_alloc.shuffle=1
.
This was suggested on #18467 (comment 185432).
