Thanks a lot for doing the lion part of this series, Andy! With this in
place, *finally* stop machine way of text patching is past us, and we
can move RISC-V out from the 20th century. ;-)

I applied your series, and Steven's series [1] to [2], and ran that on
QEMU (riscv64, ~RVA23), and on Milk-V Jupiter (Spacemit K1) with:
 * CONFIG_FTRACE_STARTUP_TEST
 * ftrace kselftest

No visible regressions, and now the ftrace kselftest can actually
complete! For the series:
