Subject: [patch 8/8] x86/fpu/xstate: Move remaining xfeature helpers to core
Date: Fri, 15 Oct 2021 01:09:40 +0200 (CEST) [thread overview]
Message-ID: <20211014230739.514095101@linutronix.de> (raw)
In-Reply-To: <20211014225711.615197738@linutronix.de>
Now that everything is mopped up, move all the helpers and prototypes into
the core header. They are not required by the outside.
