Missing & Broken Kernel Code in Oneplus Ace/Race ColorOS 12.1 Source Cross compiling

[SukeCloud]

Still getting errors from mt6895 12.1 kernel source :

using config : mgk_64_k510_defconfig and oplus6895.config
CROSS_COMPILE = aarch64-linux-gnu-

command to compile kernel :

make O=out -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- mgk_64_k510_defconfig oplus6895.config
make O=out -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

getting error :

please ask oneplus kernel team to just to test only the kernel compilation not the entire source.
Please tell me how to successfully compile the kernel. Is there a problem with the compiler used?
Thanks.
