#     powerpc/kprobes: Replace ppc_optinsn by common optinsn
#     
#     Commit 51c9c0843993 ("powerpc/kprobes: Implement Optprobes")
#     implemented a powerpc specific version of optinsn in order
#     to workaround the 32Mb limitation for direct branches.
#     
#     Instead of implementing a dedicated powerpc version, use the
#     common optinsn and override the allocation and freeing functions.
#     
#     This also indirectly remove the CLANG warning about
#     is_kprobe_ppc_optinsn_slot() not being use, and the powerpc will
#     now benefit from commit 5b485629ba0d ("kprobes, extable: Identify
#     kprobes trampolines as kernel text area")
