Pull more RISC-V updates from Palmer Dabbelt:

 - The compression format used for boot images is now configurable at
   build time, and these formats are shown in `make help`

 - access_ok() has been optimized

 - A pair of performance bugs have been fixed in the uaccess handlers

 - Various fixes and cleanups, including one for the IMSIC build failure
   and one for the early-boot ftrace illegal NOPs bug
