Linus Torvalds 1e18ed5727 ring-buffer fix for v7.1 
- Make undefsyms_base.c into a real file
 
   The file undefsyms_base.c is used to catch any symbols used by a remote
   ring buffer that is made for use of a pKVM hypervisor. As it doesn't share
   the same text as the rest of the kernel, referencing any symbols within
   the kernel will make it fail to be built for the standalone hypervisor.
 
   A file was created by the Makefile that checked for any symbols that could
   cause issues. There's no reason to have this file created by the Makefile,
   just create it as a normal file instead.

Pull ring-buffer fix from Steven Rostedt:

 - Make undefsyms_base.c into a real file

   The file undefsyms_base.c is used to catch any symbols used by a
   remote ring buffer that is made for use of a pKVM hypervisor. As it
   doesn't share the same text as the rest of the kernel, referencing
   any symbols within the kernel will make it fail to be built for the
   standalone hypervisor.

   A file was created by the Makefile that checked for any symbols that
   could cause issues. There's no reason to have this file created by
   the Makefile, just create it as a normal file instead.
