[ Upstream commit f6b4df37ebfeb47e50e27780500d2d06b4d211bd ]
CONFIG_PPC_FTRACE_OUT_OF_LINE introduced setup_ftrace_ool_stubs() to extend the ppc64le module .stubs section with an array of ftrace_ool_stub structures for each patchable function.
Fix its ppc64_stub_entry stub reservation loop to properly write across all of the num_stubs used and not just the first entry.
