Subject: [PATCH V5 3/6] riscv: Add modules to virtual kernel memory layout dump
Date: Tue, 2 Aug 2022 20:18:15 +0800 [thread overview]
Message-ID: <20220802121818.2201268-4-xianting.tian@linux.alibaba.com> (raw)
In-Reply-To: <20220802121818.2201268-1-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=y.
eg,
MODULES_VADDR - MODULES_END
0xffffffff01133000 - 0xffffffff80000000
