ftrace_low.S has just the _mcount stub and return_to_handler(). Merge this back into ftrace_mprofile.S and ftrace_64_pg.S to keep all ftrace code together, and to allow those to evolve independently. ftrace_mprofile.S is also not an entirely accurate name since this also holds ppc32 code. This will be all the more incorrect once support for -fpatchable-function-entry is added. Rename files here to more accurately describe the code: - ftrace_mprofile.S is renamed to ftrace_entry.S - ftrace_pg.c is renamed to ftrace_64_pg.c - ftrace_64_pg.S is rename to ftrace_64_pg_entry.S Signed-off-by: Naveen N Rao <naveen@kernel.org> Reviewed-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/b900c9a8bba9d6c3c295e0f99886acf3e5bf6f7b.1687166935.git.naveen@kernel.org
