  RISC-V: Remove unused code from STRICT_KERNEL_RWX (2020-05-05 17:02:14 -0700)

----------------------------------------------------------------
RISC-V Fixes for 5.7-rc5

This contains a smattering of fixes and cleanups that I'd like to target for
5.7:

* Dead code removal.
* Exporting riscv_cpuid_to_hartid_mask for modules.
* Per-CPU tracking of ISA features.
* Setting max_pfn correctly when probing memory.
* Adding a note to the VDSO so glibc can check the kernel's version without a
  uname().
* A fix to force the bootloader to initialize the boot spin tables, which still
  get used as a fallback when SBI-0.1 is enabled.
