RISC-V: Add modules to virtual kernel memory layout dump
Modules always live before the kernel, MODULES_END is fixed but MODULES_VADDR isn't fixed, it depends on the kernel size. Let's add it to virtual kernel memory layout dump. As MODULES is only defined for CONFIG_64BIT, so we dump it when CONFIG_64BIT=y. eg, MODULES_VADDR - MODULES_END 0xffffffff01133000 - 0xffffffff80000000 Reviewed-by: Guo Ren <guoren@kernel.org> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Xianting Tian <xianting.tian@linux.alibaba.com> Link: https://lore.kernel.org/r/20220811074150.3020189-5-xianting.tian@linux.alibaba.com Cc: stable@vger.kernel.org Fixes: 2bfc6cd81bd1 ("riscv: Move kernel mapping outside of linear mapping") Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
