| |
arch_check_ftrace_location() was introduced as a weak function in f7f242ff0044 ("kprobes: introduce weak arch_check_ftrace_location() helper function") to allow architectures to handle kprobes call site on their own.
Recently, the only architecture (csky) to implement arch_check_ftrace_location() was migrated to using the common version.
As a result, further cleanup the code to drop the weak attribute and rename the function to remove the architecture specific implementation.
