2008-08-07sparc64: Fix end-of-stack checking in save_stack_trace().David S. Miller
Bug reported by Alexander Beregalov. Before we dereference the stack frame or try to peek at the pt_regs magic value, make sure the entire object is within the kernel stack bounds. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-08-07powerpc/iseries: remove the old viocons driverStephen Rothwell

2008-08-07[ARM] Fix SMP booting with non-zero PHYS_OFFSETRussell King
The existing code tries to get the pmd for the temporary page table by doing: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd, PHYS_OFFSET); Since we have a two level page table, pmd_offset() is a no-op, so this just has a casting effect from a pgd to a pmd - the address argument is unused. 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>

2008-08-04sparc64: Remove all cpumask_t local variables in xcall dispatch.David S. Miller
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>
2008-08-04sparc64: Kill error_mask from hypervisor_xcall_deliver().David S. Miller

2008-08-04sparc64: Make smp_cross_call_masked() take a cpumask_t pointer.David S. Miller
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>
2008-08-04sparc64: Directly call xcall_deliver() in smp_start_sync_tick_client.David S. Miller

2008-08-04sparc64: Call xcall_deliver() directly in some cases.David S. Miller
For these cases the callers make sure: 1) The cpus indicated are online. 2) The current cpu is not in the list of indicated cpus. 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.
