[PATCH] powerpc: tracing: Avoid tracepoint duplication with DECLARE_EVENT_CLASS

irq_entry, irq_exit, timer_interrupt_entry and timer_interrupt_exit all do the same thing so use DECLARE_EVENT_CLASS to avoid duplicating everything 4 times. This saves quite a lot of space in both instruction text and data: textdata bss dec hex filename 9265 19622 1

[patch] sched, numa: Allocate node_queue on any node for offline nodes

struct node_queue must be allocated with NUMA_NO_NODE for nodes that are not (yet) online, otherwise the page allocator has a bad zonelist and results in an early crash. Tested-by: Stephen Rothwell Signed-off-by: David Rientjes --- kernel/sched/numa.c |3 ++- 1 files changed, 2 insertions

[PATCH] powerpc: Enable jump label support

When looking through some instruction traces I noticed our tracepoint checks were inline. It turns out we don't have CONFIG_JUMP_LABEL enabled. By enabling CONFIG_JUMP_LABEL we replace a load/compare/branch with a nop at every tracepoint call. For example in do_IRQ: CONFIG_JUMP_LABEL disabled:

powerc tree maintainership status

Hi Folks ! I'm going to be getting some surgery next week. In the good case, I should be officially back to work 2 weeks later, but I might end up being unavailable for longer. So while I'm away, Michael Ellerman and Paul Mackerras are going to take care of the powerpc tree. I'll make sure Paul a

[git pull] Please pull powerpc.git next branch

Hi Linus ! Here are the powerpc goodies for 3.5. Main highlights are: - Support for the NX crypto engine in Power7+ - A bunch of Anton goodness, including some micro optimization of our syscall entry on Power7 - I converted a pile of our thermal control drivers to the new i2c APIs (essen

[PATCH v2 0/2] Add pcibios_device_change_notifier

This patchset is for PCI hotplug. pcibios_setup_bus_devices which sets DMA and IRQs of PCI device is called only when boot. DMA setting in probe for PCI driver, like dma_set_mask, does not work on powerpc platform. So it is need to set DMA and IRQs of PCI device when hotplug. 1. Moving pcibios_s

Handling spin table in kdump

Hi I came across the following issue while testing Kdump on an SMP board(Currituck) running a non-SMP kernel. Even though the kernel is UP, the device-tree has the nodes for second CPU and the related details. The kexec tool adds the spin table area as a reserved section in the device tree f
