Do we really need this change ? Given that A72 is using the generic_v8
table,
it will automatically be supported via the GENERIC_V8 target. That was
added
just for this purpose. The pre-existing targets were preserved so that
we don't break the ABI for older user space.
Yes, this works for qemu with "-cpu host". But if it specifies the cpu
type with "-cpu cortex-a72". It will fail without this patch.
Thats because you specify the expected target from the kernel in Qemu.
I don't know what are the plans for Qemu. Are we going to add every single
ARM CPU released to the target list both in Kernel and Qemu ? e.g, what about
A35, A73 and others from the partners ?

The corresponding qemu patches could be found at [1].
