Subject: [PATCH 02/26] x86, pkeys: Add Kconfig option
Date: Wed, 16 Sep 2015 10:49:04 -0700 [thread overview]
Message-ID: <20150916174904.996E5E23@viggo.jf.intel.com> (raw)
In-Reply-To: <20150916174903.E112E464@viggo.jf.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.
