2008-03-20[POWERPC] Hide resources on Axon PCIE root complex nodesMichael Ellerman
The PCI bridge representing the PCIE root complex on Axon, contains device BARs for a memory range and ROM that define inbound accesses. This confuses the kernel resource management code -- the resources need to be hidden when Axon is a host bridge.

2008-03-20[POWERPC] Fix cell IOMMU code to cope with empty dma-ranges and non-PCI devicesMichael Ellerman
The cell IOMMU code to parse the dma-ranges properties, used for the fixed mapping, was broken in two ways for some devices. Firstly it didn't cope with empty dma-ranges properties. An empty property implies no translation so can be safely skipped. The code also wrongly assumed it would be looking at PCI devices, and hard coded the number of address and size cells.

2008-03-20[POWERPC] Fix build failure for tqm8540 and sbc85xx defconfigsPaul Gortmaker
The wrapper script didn't have entries for the TQM8540 board and the SBC8548 or SBC8560 boards. I've assumed that the TQM8540 console is 8250 based and not CPM based by looking at its defconfig. There was also a trailing * on the TQM8555 entry that I removed too.

2008-03-20[POWERPC] Fix PMU + soft interrupt disable bugAnton Blanchard
Since the PMU is an NMI now, it can come at any time we are only soft disabled. We must hard disable around the two places we allow the kernel stack SLB and r1 to go out of sync. Otherwise the PMU exception can force a kernel stack SLB into another slot, which can lead to it getting evicted, which can lead to a nasty unrecoverable SLB miss in the exception entry code.

2008-03-20[POWERPC] user_regset PTRACE_SETREGS regression fixRoland McGrath
The PTRACE_SETREGS request was only recently added on powerpc, and gdb does not use it. So it slipped through without getting all the testing it should have had. The user_regset changes had a simple bug in storing to all of the 32-bit general registers block on 64-bit kernels. This bug only comes up with PTRACE_SETREGS, not PPC_PTRACE_SETREGS. It causes a BUG_ON to hit, so this fix needs to go in ASAP. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-03-18IDE: Make taskfile interface more robust wrt unexpected end-of-commandLinus Torvalds
Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE rather than using the old REQ_TYPE_ATA_CMD model, we need to also emulate the lack of full taskfile data that comes with the old command model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl rather than using the HDIO_DRIVE_TASK[FILE] ioctls). In particular, this means that we should handle command completion the more relaxed way that the old drive_cmd_intr() code did. It allows commands to finish early even if they don't use up all the data that we thought we had for them. This fixes a regression seen by Anders Eriksson where some SMART commands sent by smartd would cause a boot-time system hang on his machine because the IDE command handling code didn't realize that the command had completed.

2008-03-19sched: tune multi-core idle balancingIngo Molnar
WAKE_IDLE is too agressive on multi-core CPUs with the new wake-affine code, keep it on for SMT/HT balancing alone (where there's no cache affinity at all between logical CPUs). Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-03-19sched: wakeup-buddy tasks are cache-hotIngo Molnar
Wakeup-buddy tasks are cache-hot - this makes it a bit harder for the load-balancer to tear them apart. (but it's still possible, if the load is sufficiently assymetric) Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-03-19sched: improve affine wakeupsIngo Molnar
improve affine wakeups. Maintain the 'overlap' metric based on CFS's sum_exec_runtime - which means the amount of time a task executes after it wakes up some other task. Use the 'overlap' for the wakeup decisions: if the 'overlap' is short, it means there's strong workload coupling between this task and the woken up task. If the 'overlap' is large then the workload is decoupled and the scheduler will move them to separate CPUs more easily. ( Also slightly move the preempt_check within try_to_wake_up() - this has no effect on functionality but allows 'early wakeups' (for still-on-rq tasks) to be correctly accounted as well.) Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-03-18fsldma: Fix the DMA halt when using DMA_INTERRUPT async_tx transfer.Zhang Wei
The DMA_INTERRUPT async_tx is a NULL transfer, thus the BCR(count register) is 0. When the transfer started with a byte count of zero, the DMA controller will triger a PE(programming error) event and halt, not a normal interrupt.

This fixes a 2.6.25 regression reported by Alex Chiang. Invoke pciehp_enable_slot() at startup only when pciehp_force=1. Some HP equipment apparently cannot cope with it otherwise.

This was the original design back in October 2007, but Kristen suggested we try without it first: Kristen Carlson Accardi wrote: >I think it would be ok to try allowing the slot to be enabled when not >using pciehp_force mode.
