I'm also seeing other architectures affected looking at -next, I see the
Avenger96 (32 bit Arm) and VisionFive 2 (RISC-V) with bisects coming out
on the merge of the branch or on

# first bad commit: [10d91dac2ea5ddf04e647cf862430d1051adb839] vdso/datastore: Allocate data pages dynamically

It looks like the uniprocessor boards I've got (at91sam9g20ek,
