I tried to bisect things down a bit, but as some later fixes are required (at one point, date was returning the start epoch and never increasing), this hasn't worked too well. But I'm guessing since I see: "CROSS_COMPILE_COMPAT not defined or empty, the compat vDSO will not be built", and the system is half working, I'm guessing this is an issue with just the 32bit code failing. While I can try to sort out the proper CROSS_COMPILE_COMPAT in my build environment, I assume userland shouldn't be crashing if that value isn't set.
Any chance this issue has already been raised?
First I've seen of it, although Vincenzo is likely to know better than me. In the meantime, please can you share your .config?
I think the key is: CROSS_COMPILE_COMPAT not defined or empty. And then run 32bit userspace.
The part I was wondering about is whether the vectors page has been disabled at the same time, since I'm fairly sure I've already been running with the above (but I can easily double-check).
