参数：

类型参数名称
pmd_t *pmd
unsigned longaddr
unsigned longend
381  以addr小于end循环
384  next等于pmd_addr_end(addr, end)
386  如果非pmd_present( * pmd)则继续下一循环
389  如果kasan_pte_table( * pmd)则
390  如果IS_ALIGNED(addr, PMD_SIZE)且IS_ALIGNED(next, PMD_SIZE)则pmd_clear(pmd)
393  继续下一循环
395  pte等于pte_offset_kernel(pmd, addr)
396  kasan_remove_pte_table(pte, addr, next)
397  kasan_free_pte(pte_offset_kernel(pmd, 0), pmd)
