Describe the bug

I'm trying to build kernel for raspiberrypi-4B with latest commit 5a52cae and I'm facing build issue as following:
../arch/arm64/include/asm/atomic_ll_sc.h:318:38: error: ‘__uint128_t’ undeclared (first use in this function); did you mean ‘int128’?
318 | : "=&r" (tmp), "=&r" (ret), "+Q" (*(__uint128_t *)ptr)

Steps to reproduce the behaviour

git clone --depth=1 https://github.com/raspberrypi/linux
KERNEL=kernel8
IMAGE=Image.gz
make O=./build/ bcm2711_defconfig
make O=./build/ -j $IMAGE modules dtbs

Device (s)

If you are trying to build a 64-bit kernel on a 32-bit OS (file $(which ls) will tell you) then you need to treat is as a cross-compile; see https://www.raspberrypi.com/documentation/computers/linux_kernel.html#cross-compiling-the-kernel for instructions.

ok, I've switched to build 32-bit kernel on 32-bit OS, but when I do that, I'm facing below issue.
KERNEL=kernel7l
make bcm2711_defconfig

make -j4 zImage modules dtbs
make: *** No rule to make target 'zImage'. Stop.

I always include the ARCH=arm declaration - does that help?

KERNEL=kernel7l
make ARCH=arm bcm2711_defconfig
make ARCH=arm -j4 zImage modules dtbs

(The KERNEL=kernel7l line is only necessary if you use it later on during the installation, e.g.
sudo cp arch/arm/boot/zImage /boot/firmware/$KERNEL.img)

[sadhanpawar]

it works!
