RISC-V: Add dynamic ftrace support for RISC-V platforms This patch set includes the building blocks of dynamic ftrace features for RISC-V machines. I'm afraid I'm not very familiar with ftrace, but the code looks OK to me. It's been used to track down a performance problem in our SPI driver and appears to work acceptably, but we haven't given it a whole lot of banging yet so there might still be some bugs lurking around somewhere.
