[RFC][PATCH 0/2 v2] tracing/x86_32: Remove non DYNAMIC_FTRACE and mcount support

From: Steven Rostedt
Date: Fri May 10 2019 - 12:40:03 EST

There's no need to support either DYNAMIC_FTRACE=n or mcount (non fentry)
in x86_32. As the static tracing (DYNAMIC_FTRACE=n) does not support
fentry, we can just remove it, as the static tracing is only around to
test the static tracing in generic code as other architectures have it

This will allow also allow us to remove klp_check_compiler_support()
in later patches.

Steven Rostedt (VMware) (2):
ftrace/x86_32: Remove support for non DYNAMIC_FTRACE
ftrace/x86: Remove mcount support
