[PATCH][IMPISH] UBUNTU: [Config] Enable CONFIG_RANDOMIZE_KSTACK_OFFSET_DEFAULT

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Kernel stack offset randomization is a useful security feature
that should be enabled. Benchmarking showed that the impact is
within the noise of various microbenchmarks so I believe this
has some added benefit with minimal performance impact. The
security folk believe this is worth enabling, so lets switch
it on.
