Subject: [PATCH V2 2/2] riscv: Add modules to virtual kernel memory layout dump
Date: Thu, 14 Jul 2022 10:59:01 +0800 [thread overview]
Message-ID: <20220714025901.359695-3-xianting.tian@linux.alibaba.com> (raw)
In-Reply-To: <20220714025901.359695-1-xianting.tian@linux.alibaba.com>
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.
eg,
MODULES_VADDR - MODULES_END
0xffffffff01133000 - 0xffffffff80000000
