打入 patch / diff：
git apply xxx.patch
git apply xxx.diff
检查 patch / diff：
git apply --check xxx.patch
git apply --check xxx.diff
若git和需要打patch的文件不在一个目录：(git在framework下，patch要打入frameworks/base/下)
git apply --check --directory=base/ xxx.patch
git apply --directory=base/ xxx.patch
** git am 后面会说到，以及生产patch和打入patch的一些命令参数**

1. 检查patch是否可用，没显示文字，就说明可用，且无冲突；
   git apply --check ~/patch/patch/0001-add-11111.patch
