----------------------------------------------------------------
RISC-V updates for v6.18-rc5
Some RISC-V updates for v6.18-rc5, including:
- A fix to disable KASAN checks while walking a non-current task's
stackframe (following x86)
- A fix for a kvrealloc()-related memory leak in
module_frob_arch_sections()
- Two replacements of strcpy() with strscpy()
- A change to use the RISC-V .insn assembler directive when possible
to assemble instructions from hex opcodes
- Some low-impact fixes in the ptdump code and kprobes test code
