  riscv: Fix early ftrace nop patching (2024-05-23 08:22:17 -0700)

----------------------------------------------------------------
RISC-V Patches for the 6.10 Merge Window, Part 2

* 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.
