Subject: [for-linus][PATCH 04/27] csky: ftrace: Drop duplicate implementation of
arch_check_ftrace_location()
From: Punit Agrawal <punitagrawal@...il.com>
The csky specific arch_check_ftrace_location() shadows a weak
implementation of the function in core code that offers the same
functionality but with additional error checking.
Drop the architecture specific function as a step towards further
cleanup in core code.
