函数名称：machine_kexec_page_table_set_one
函数原型：static void machine_kexec_page_table_set_one(pgd_t *pgd, pmd_t *pmd, pte_t *pte, unsigned long vaddr, unsigned long paddr)
返回类型：void
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| pgd_t * | pgd | |
| pmd_t * | pmd | |
| pte_t * | pte | |
| unsigned long | vaddr | |
| unsigned long | paddr |
| 98 | pgd加等于he pgd page can be thought of an array like this: pgd_t[PTRS_PER_PGD]* this macro returns the index of the entry in the pgd page which would* control the given virtual address(vaddr) |
| 103 | p4d等于p4d_offset(pgd, vaddr) |
| 104 | pud等于pud_offset(p4d, vaddr) |
| 105 | pmd等于pmd_offset(pud, vaddr) |
| 106 | 如果非pmd_val( * pmd)按位与_PAGE_PRESENT的值则set_pmd(pmd, __pmd(__pa(pte) | _PAGE_TABLE)) |
| 108 | pte等于pte_offset_kernel(pmd, vaddr) |
