Not everything. In-order CPUs such as Cortex-A7 and Cortex-A53 are not affected. Confirmed by Arm at https://developer.arm.com/support/security-update "all other Arm cores are NOT affected"

Doesn’t Spectre just require speculative fetching? In which case in order is not sufficient as to guarantee immunity.

It’s Meltdown that relies on out of order execution.
