The problem should be fixed by this commit: Its not that easy. __alloc_percpu falls back to kzalloc() on UP and this can result in unique bootstrap problems with UP since the bootstrap array is no longer there. Does the UP kernel boot? Why did this ever build on my UP configuration tests? Hmmm... I only tested x86_64 UP. This was 32 bit UP I guess.
