函数名称：Note: this doesn't free the actual pages themselves. That* has been handled earlier when unmapping all the memory regions.

函数原型：static void free_pte_range(struct mmu_gather *tlb, pmd_t *pmd, unsigned long addr)

返回类型：void

参数：

类型参数名称
struct mmu_gather *tlb
pmd_t *pmd
unsigned longaddr
216  token等于pmd_pgtable( * pmd)
217  pmd_clear(pmd)
218  For things like page tables caches (ie caching addresses "inside" the* page tables, like x86 does), for legacy reasons, flushing an* individual page had better flush the page table caches behind it. This* is definitely how x86 works, for example(tlb, token, addr)
219  mm_dec_nr_ptes(mm)
