Linux 2.6.11 does not build SMP

[Kip Macy <kip.macy@gmail.com>]

You aren't defining pmd_val_ma for CONFIG_SMP and LINUX_VERSION_CODE >
KERNEL_VERSION(2,6,0)
/* Linux 2.6 isn't using the traditional batched interface. */
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,0)
#define QUEUE_SIZE 2048
#define pte_offset_kernel pte_offset
#define pmd_val_ma(v) (v).pmd;
#define pud_t pgd_t
#define pud_offset(d, va) d
#else
#ifdef CONFIG_SMP
#define QUEUE_SIZE 1
#else
#define QUEUE_SIZE 128
#define pmd_val_ma(v) (v).pud.pgd.pgd;
#endif
#endif

unfortunately this doesn't stop you from using it:
void queue_l2_entry_update(pmd_t *ptr, pmd_t val)
{
    int cpu = smp_processor_id();
    int idx;
    unsigned long flags;
    spin_lock_irqsave(&update_lock, flags);
    idx = per_cpu(mmu_update_queue_idx, cpu);
    per_cpu(update_queue[idx], cpu).ptr = virt_to_machine(ptr);
    per_cpu(update_queue[idx], cpu).val = pmd_val_ma(val);
    increment_index();
    spin_unlock_irqrestore(&update_lock, flags);
}

void xen_l2_entry_update(pmd_t *ptr, pmd_t val)
{
    int cpu = smp_processor_id();
    int idx;
    unsigned long flags;
    spin_lock_irqsave(&update_lock, flags);
    idx = per_cpu(mmu_update_queue_idx, cpu);
    per_cpu(update_queue[idx], cpu).ptr = virt_to_machine(ptr);
    per_cpu(update_queue[idx], cpu).val = pmd_val_ma(val);
    increment_index_and_flush();
    spin_unlock_irqrestore(&update_lock, flags);
}
