Not sure what you mean by that.

The only issue I see compatibility-wise is that ARM doesn't have a standard method for an OS kernel to auto-discover peripherals. x86_64 has UEFI and ACPI. ARM manufacturers could adopt that if they wanted to, but apparently they (mostly) don't want to.

Otherwise, non-assembly code written for x86_64 tends to run just fine on ARM, when compiled for it.

ARM manufacturers don't want compatibility.

Traditionally the Linux-on-ARM market has sucked because every single board computer and phone and tablet has needed its own specially compiled kernel with its own set of kernel patches, and probably its own half-assed Linux distro that never gets any updates.

You can't even buy a USB wifi or bluetooth stick and expect it to work without checking the chipset - let alone use a single distro across the BeagleBone Black, the Xilinx Zinq, the iMX6 and the RPi.
