An upcoming change will allocate the datapages dynamically instead of as part of the kernel image. Such pages can only be mapped through 'struct page' and not through PFNs.
I'm seeing some boot failures on some arm64 platforms in -next which are bisecting to this patch in -next. Unfortunately the diagnostics aren't super useful, we seem to just stop making progress in userspace with no obvious output. One sample log from the FVP is:
https://lava.sirena.org.uk/scheduler/job/2036229#L1268
which isn't super instructive. Not all platforms seem to be affected, I've seen this on at least the Arm FVP, Orion O6 and Libretech Renegade Elite. The diagnostics aren't very clear here but given that I'm seeing the same issue and bisect result on multiple platforms it seemed worth mentioning. Some platforms do seem fine.
Can you try
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers/vdso
which is rc1 based and only contains the VDSO changes. That might give us a better hint.
