 $GITSUBJ: Clean up includes
 
-Clean up includes so that osdep.h is included first and headers
-which it implies are not included manually.
-
 This commit was created with scripts/clean-includes.
 
+All .c should include qemu/osdep.h first.  The script performs three
+related cleanups:
+
+* Ensure .c files include qemu/osdep.h first.
+* Including it in a .h is redundant, since the .c  already includes
+  it.  Drop such inclusions.
+* Likewise, including headers qemu/osdep.h includes is redundant.
+  Drop these, too.
