Subject: RISC-V: Add modules to virtual kernel memory layout dump
From: Xianting Tian <xianting.tian@xxxxxxxxxxxxxxxxx>
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
