DO NOT USE THE BUILD HERE UNLESS YOU KNOW WHAT YOU ARE DOING

Initial build for mondrian

• All kernel module are OSS. goodix_core.ko and xiaomi_touch.ko are reverse engineered. The OSS version is still a little buggy.
• Enable some basic kernel features, such as SYSVIPC, PID_NS and USER_NS. More is needed for docker.
• SEPolicy modifications for PFA.
• Reserve more space and inode in vendor partition.
• Temporarily disable kernel panic on oops (/proc/sys/kernel/panic_on_oops).
• Temporarily enable CONFIG_MODULE_FORCE_LOAD.
• All builds published now are userdebug builds signed with test keys. I might publish builds signed with my keys in the future.
