[PATCH v2 2/7] x86/ftrace: Fix use of flags in ftrace_replace_code()

From: Naveen N. Rao <hidden>
Date: 2019-06-27 11:24:20
Also in: linuxppc-dev
Subsystem: function hooks (ftrace), the rest, x86 architecture (32-bit and 64-bit) · Maintainers: Steven Rostedt, Masami Hiramatsu, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen

In commit a0572f687fb3c ("ftrace: Allow ftrace_replace_code() to be
schedulable), the generic ftrace_replace_code() function was modified to
accept a flags argument in place of a single 'enable' flag. However, the
x86 version of this function was not updated. Fix the same.

Fixes: a0572f687fb3c ("ftrace: Allow ftrace_replace_code() to be schedulable")
