Merge tag 'riscv-for-linus-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:
 "This contains a handful of fixes I'd like to target for rc3.

  Most of them fix issues with the conversion of our vDSO to C. There is
  also one fix to the SiFive PRCI driver that I picked up as it's
  causing boot issues on the hardware.

   - A fix to allow kernels with dynamic ftrace to use the vDSO.

   - Some build fixes for the C vDSO functions.

   - A fix to the PRCI driver's memory allocation, which was the cause
     of some boot panics with FREELIST_RANDOM"
