This patch tweaks idle thread setup semantics a bit: instead of setting NEED_RESCHED in init_idle(), we do an explicit schedule() before calling into cpu_idle(). This patch, while having no negative side-effects, enables wider use of cond_resched()s. (which might happen in the stock kernel too, but it's particulary important for voluntary-preempt) Signed-off-by:

Currently we cap request allocations at q->nr_requests, but we allow a batching io context to allocate up to 32 more (default setting). This can flood the queue with request allocations, with only a few batching processes. The real fix would be to limit the number of batchers, but as that isn't currently tracked, I suggest we just cap the maximum number of allocated requests to eg 50% over the limit. This was observed in real life, users typically see this as vmstat bo numbers going off the wall with seconds of no queueing afterwards. Behaviour this bursty is not beneficial. Signed-off-by:

This patch lengthens the delay between DET setting and clearing for COMMRESET from 400us to 1ms. I couldn't find any requiremen regarding the duration of COMMRESET in SATA I/II specs but AHCI-1.1 10.4.2 states that it should be at least 1ms. Signed-off-by: -

The amd8111e driver directly assigns the DMA mask to the dma_mask member of the struct pci_dev instead of using pci_set_dma_mask(). This makes the call to pci_dma_supported() redundant as pci_set_dma_mask() does this check. I do not own this device so I only compile-tested this patch.

For boards that invert the SMC91x IRQ line (maybe an FPGA inverts it), the set_irq_type() call can't assume IRQT_RISING. These particular boards currently use OMAP-specific calls to change the trigger type, but the boards break when set_irq_type() stops being a NOP.

Don't auto-configure yenta sockets for PCMCIA devices if it is connected to the root PCI bus on the x86 or x86_64 architectures. Previously, this was handled by the "ioport_resource"/"iomem_resource" check a few lines below, but with the new ACPI-based resource handling this doesn't catch all cases any longer. pci-yenta-cardbus-fix.patch and this patch should solve the initialization time trouble. However, the ACPI-based PCI resource handling is badly broken, IMHO: - many resources of devices don't show up in the resource trees ( /proc/iomem and /proc/ioports) any longer. This means that PCMCIA, but also possibly other subsystems (ISA, PnP, ...) do not know which resources it cannot use. - verify_root_windows() should fail if there are no iomem _or_ ioport resources, not only if there are no iomem _and_ ioport resources.

The PCMCIA card services layer is never setting the i/o map attributes when SS_CAP_STATIC_MAP is specified. Net result, sockets' set_io_map() calls always see requests with most flags clear, meaning 8 bit access. For hardware that always autosizes, that won't matter; and all current STATIC_MAP drivers ignore those attributes. A new driver (for at91rm9200) suffers badly from this, since this forces everything into 8 bit mode and that breaks both (a) cards requiring 16 bit access, and (b) ide-cs; but of course 8-bit cards work OK (as does accessing card attributes). So this patch arranges to pass the attributes down, matching the behavior for non-static mappings (using the first/only I/O window). Signed-off-by:
