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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
but not DYNAMIC_FTRACE.

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

      ftrace/x86_32: Remove support for non DYNAMIC_FTRACE
      ftrace/x86: Remove mcount support
