+================
+启动时的内存管理
+================
+
+系统初始化早期“正常”的内存管理由于没有设置完毕无法使用。但是内核仍然需要
+为各种数据结构分配内存,例如物理页分配器。
+
+一个叫做 ``memblock`` 的专用分配器执行启动时的内存管理。特定架构的初始化
+必须在setup_arch()中设置它,并在mem_init()函数中移除它。
+
+一旦早期的内存管理可用,它就为内存分配提供了各种函数和宏。分配请求可以指向
+第一个(也可能是唯一的)节点或NUMA系统中的某个特定节点。有一些API变体在分
+配失败时panic,也有一些不会panic的。
+
+Memblock还提供了各种控制其自身行为的API。
+
+Memblock概述
+============
+
+该API在以下内核代码中:
+
+mm/memblock.c
+
+
+函数和结构体
+============
+
+下面是关于memblock数据结构、函数和宏的描述。其中一些实际上是内部的,但由于
+它们被记录下来,漏掉它们是很愚蠢的。此外,阅读内部函数的注释可以帮助理解引
+擎盖下真正发生的事情。
+
+该API在以下内核代码中:
+
+include/linux/memblock.h
+mm/memblock.c
