[PATCH 6.18 003/250] sched/fair: Separate se->vlag from se->vprot

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ingo Molnar <[email protected]>

[ Upstream commit 80390ead2080071cbd6f427ff8deb94d10a4a50f ]

There's no real space concerns here and keeping these fields
in a union makes reading (and tracing) the scheduler code harder.
