From 366dd4ea9d5f0eb78fdf4982d76506f99480ec0a Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Wed, 13 Apr 2016 22:27:22 +0200 Subject: parisc: Fix ftrace function tracer Fix the FTRACE function tracer for 32- and 64-bit kernel. The former code was horribly broken. Reimplement most coding in assembly and utilize optimizations, e.g. put mcount() and ftrace_stub() into one L1 cacheline.
