Will Deacon 209479bfff arm64: ftrace: Ensure module ftrace trampoline is coherent with I-side ... commit b6143d10d2 upstream. The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1beb ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.
