Alexandre Ghiti 08a2117e83 riscv: Fix text patching when IPI are used 
[ Upstream commit c97bf62996 ]

For now, we use stop_machine() to patch the text and when we use IPIs for
remote icache flushes (which is emitted in patch_text_nosync()), the system
hangs.

So instead, make sure every CPU executes the stop_machine() patching
function and emit a local icache flush there.
