next-20081103 fails to boot for me because of (1). Commit right before it
boot normally. It hangs right after "Booting the kernel" with the only message

	PANIC: early exception 06 rip 10:ffffffff80523801 error 0 cr2 0

x86_64, no debugging config (all debugging fails same way)
Core 2 Duo, NR_CPUS=2.

    cpualloc: the allocator
    The per cpu allocator allows dynamic allocation of memory on all
    processors simultaneously.  A bitmap is used to track used areas.  The
    allocator implements tight packing to reduce the cache footprint and
    increase speed since cacheline contention is typically not a concern for
    memory mainly used by a single cpu.  Small objects will fill up gaps left
    by larger allocations that required alignments.
    The size of the cpu_alloc area can be changed via the percpu=xxx kernel
