  riscv: remove unused handle_exception symbol (2021-05-06 09:40:16 -0700)

----------------------------------------------------------------
RISC-V Fixes for the Merge Window, Part 2

* A fix to avoid over-allocating the kernel's mapping on !MMU systems,
  which could lead to up to 2MiB of lost memory.
* The SiFive address extension errata only manifest on rv64, they are
  now disabled on rv32 where they are unnecessary.

There are also a pair of late-landing cleanups.

----------------------------------------------------------------
Geert Uytterhoeven (2):
      riscv: Only extend kernel reservation if mapped read-only
      riscv: Consistify protect_kernel_linear_mapping_text_rodata() use

Rouven Czerwinski (1):
      riscv: remove unused handle_exception symbol

Vincent Chen (1):
      riscv: enable SiFive errata CIP-453 and CIP-1200 Kconfig only if CONFIG_64BIT=y
