Subject: [PATCH 02/25] x86, pkeys: Add Kconfig option


From: Dave Hansen <dave.hansen@...ux.intel.com>

I don't have a strong opinion on whether we need a Kconfig prompt
or not.  Protection Keys has relatively little code associated
with it, and it is not a heavyweight feature to keep enabled.
However, I can imagine that folks would still appreciate being
able to disable it.

We will hide the prompt for now.
