simple_ring_buffer uses local_set() and cmpxchg() on unsigned long. Add
them to undefsyms_base.c to extend the allowlist for the parisc
architecture.

tracing: Make undefsyms_base.c a first-class citizen2026-04-22T15:24:41ZPaolo Bonzinipbonzini@redhat.com2026-04-21T10:04:55Zurn:sha1:5335e318ad3cf12d905de27e3be4e7fd7b1c6746
Linus points out that dumping undefsyms_base.c form the Makefile
is rather ugly, and that a much better course of action would be
to have this file as a first-class citizen in the git tree.
This allows some extra cleanup in the Makefile, and the removal of
the .gitignore file in kernel/trace.
