    Subject[PATCH 5.15 058/779] RISC-V: Add modules to virtual kernel memory layout dump
    Date
    From: Xianting Tian <xianting.tian@linux.alibaba.com>

    commit f9293ad46d8ba9909187a37b7215324420ad4596 upstream.

    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
