[PATCH 0/2] riscv: fix kprobes on minimal kernel configs

When building with an allnoconfig-derived minimal configuration
(without CONFIG_STRICT_MODULE_RWX), kprobes fails because
instruction slot pages from EXECMEM_KPROBES are read-only and
patch_map() bypasses the fixmap writable alias.

These two patches fix the infrastructure.

  riscv: mm: make EXECMEM_KPROBES writable without ARCH_HAS_EXECMEM_ROX
  riscv: patch: skip fixmap mapping when kernel text is already writable
