#     
#     Pull RISC-V fixes from Palmer Dabbelt:
#     
#      - 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
#     
#      - A pair of late-landing cleanups
#     
#     * tag 'riscv-for-linus-5.13-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
#       riscv: remove unused handle_exception symbol
#       riscv: Consistify protect_kernel_linear_mapping_text_rodata() use
#       riscv: enable SiFive errata CIP-453 and CIP-1200 Kconfig only if CONFIG_64BIT=y
#       riscv: Only extend kernel reservation if mapped read-only
