`lockdep_init` 初始化 [lock validator](https://www.kernel.org/doc/Documentation/locking/lockdep-design.txt). 其实现是相当简单的，它只是初始化了两个哈希表 [list_head](https://github.com/MintCN/linux-insides-zh/blob/master/DataStructures/dlist.md)并设置`lockdep_initialized` 全局变量为`1`。

After this we set the limit for the `memblock` allocation with the `memblock_set_current_limit` function (read more about `memblock` you can in the [Linux kernel memory management Part 2](https://github.com/MintCN/linux-insides-zh/blob/master/mm/linux-mm-2.md)), it will be `ISA_END_ADDRESS` or `0x100000` and fill the `memblock` information according to `e820` with the call of the `memblock_x86_fill` function. You can see the result of this function in the kernel initialization time:

从前面的介绍我们知道 `param_kmemcheck` 可能存在三种情况：`0` (使能), `1` (禁止) or `2` (一次性)。 `param_kmemcheck` 的实现很简单：将command line传递的 `kmemcheck` 参数的值由字符串转换为整数，然后赋值给变量 `kmemcheck_enabled` 。
