From: Todd Kjos <tkjos@google.com> aosp inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7YFU9 Reference: https://android.googlesource.com/kernel/common/+/943c3b3124d2 ------------------------------------------------- Vendor hooks required explicitly defining macros or inline functions to handle the non-GKI build case (!CONFIG_ANDROID_VENDOR_HOOKS). Added support for generating them automatically so the macros are no longer required. Both models are now supported so we can transition.
