From ebe1cd530fb2f6450656758bd904cfb5767f8d33 Mon Sep 17 00:00:00 2001

Subject: s390/ctlreg: rename ctl_reg.h to ctlreg.h

Rename ctl_reg.h to ctlreg.h so it matches not only ctlreg.c but also
other control register related function, union, and structure names,
which all come with a ctlreg prefix.
