函数名称：Parse build ID from 64-bit ELF

函数原型：static int stack_map_get_build_id_64(void *page_addr, unsigned char *build_id)

返回类型：int

参数：

类型参数名称
void *page_addr
unsigned char *build_id
224  ehdr等于page_addr
229  如果e_phnum大于PAGE_SIZE减sizeof(Elf64_Ehdr)的差除sizeof(Elf64_Phdr)则返回:负EINVAL
233  phdr等于page_addr加sizeof(Elf64_Ehdr)
235  以i小于e_phnum循环如果p_type恒等于PT_NOTE则
237  返回:Parse build id from the note segment. This logic can be shared between* 32-bit and 64-bit system, because Elf32_Nhdr and Elf64_Nhdr are* identical.
240  返回:负EINVAL
