linux - 为小米设备构建 linux 内核时出错

Question

在构建内核时出现错误：

In file included from ../arch/arm64/kernel/sys.c:27:
../include/linux/syscalls.h:195:18: warning: ‘sys_arm64_personality’ alias between functions of incompatible types ‘long int(unsigned int)’ and ‘long int(long int)’ [-Wattribute-alias=]
error, forbidden warning: syscalls.h:195
make[2]: *** [../scripts/Makefile.build:339: arch/arm64/kernel/sys.o] Error 1
make[1]: *** [/home/z/kernel_dev/kernel_olive_lolz-stock/Makefile:1100: arch/arm64/kernel] Error 2
make[1]: *** Waiting for unfinished jobs....

完全登录pastebin。
内核源代码，我尝试构建的。而且它不是官方来源，因为它们已经坏了。

您可以通过在内核/Makefile 中添加以下行来修复“属性别名”警告：

KBUILD_CFLAGS += $(调用 cc-disable-warning, 属性别名)
