(Get the code!)
In theory, we could enable HIGHMEM and VMSPLIT_2G (not VMSPLIT_3G) for arm32 kernel to workaround this issue, with the 2G user space and 2G kernel space, those boards (rpi2/3 boards) with only 1G physical ram will not map ram to highmem region.
But I remember setting VMSPLIT_2G will break the SD card on rpi4, make the rpi4 can't mount the rootfs on the sd card. I will retest VMSPLIT_2G setting, maybe with the updated patches, the sd controller can work with VMSPLIT_2G.
