[PATCH v5 09/10] powerpc64/ftrace: Use the generic version of ftrace_replace_code()
From: Naveen N. Rao <hidden>
Date: 2018-04-19 07:05:08
Subsystem:
function hooks (ftrace), linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

Our implementation matches that of the generic version, which also handles FTRACE_UPDATE_MODIFY_CALL. So, remove our implementation in favor of the generic version. Signed-off-by: Naveen N.
