Subject[RFC PATCH 2/4] x86/ftrace: Fix use of flags in ftrace_replace_code()
Date
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")
Signed-off-by: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com>

I haven't yet tested this patch on x86, but this looked wrong so sending
this as a RFC.
