Fix it now; it doesn't really need to include mach/i2c.h at all. Successfully build tested with pnx4008_defconfig, which had failed in linux-next.

So this can't work. Normally, we'd do: pgd = pgd_offset(&init_mm, PHYS_OFFSET); ... pmd = pmd_offset(pgd, PHYS_OFFSET); to get the pmd you want. However, pgd_offset() takes the mm_struct, not the (unattached) pgd we just allocated. So, instead use: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET); Reported-by: Antti P Miettinen <ananaza@iki.fi> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the xcall delivery implementation is cpumask agnostic, so we can pass around pointers to const cpumask_t objects everywhere. The sad remaining case is the argument to arch_send_call_function_ipi(). Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It can eat up a lot of stack space when NR_CPUS is large. We retain some of it's functionality by reporting at least one of the cpu's which are seen in error state. Signed-off-by: David S. Miller <davem@davemloft.net>

Now all of the xcall dispatch implementations do not need to be mindful of details such as "is current cpu in the list?" and "is cpu online?" Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea is that we'll use this cpu list array and mondo block even for non-hypervisor platforms. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideally this could be simplified further such that we could pass the pointer down directly into the xcall_deliver() implementation. But if we do that we need to do the "cpu_online(cpu)" and "cpu != self" checks down in those functions. Signed-off-by: David S. Miller <davem@davemloft.net>

Therefore we can pass a pointer to the mask directly. One of the motivations in this transformation is to make use of "&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant data in the kernel and thus takes up no stack space. Hopefully someone in the future will change the interface of arch_send_call_function_ipi() such that it passes a const cpumask_t pointer so that this will optimize ever further.
