函数名称：subsection_map_init
函数原型：void __init subsection_map_init(unsigned long pfn, unsigned long nr_pages)
返回类型：void
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| unsigned long | pfn | |
| unsigned long | nr_pages |
| 233 | end_sec等于pfn_to_section_nr(pfn + nr_pages - 1) |
| 234 | start_sec等于pfn_to_section_nr(pfn) |
| 236 | 如果非nr_pages则返回 |
| 243 | pfns等于两数取小(nr_pages, PAGES_PER_SECTION - (pfn & ~PAGE_SECTION_MASK)) |
| 245 | ms等于__nr_to_section(nr) |
| 246 | subsection_mask_set(subsection_map, pfn, pfns) |
| 248 | pr_debug("%s: sec: %lu pfns: %lu set(%d, %d)\n", __func__, nr, pfns, subsection_map_index(pfn), subsection_map_index(pfn + pfns - 1)) |
