* leds: leds-gpio - fix a section mismatchZhenwen Xu2009-06-23
| | | | | | | | | | | | WARNING: drivers/leds/leds-gpio.o(.text+0x153): Section mismatch in reference from the function gpio_led_probe() to the function .devinit.text:create_gpio_led() The function gpio_led_probe() references the function __devinit create_gpio_led(). This is often because gpio_led_probe lacks a __devinit annotation or the annotation of create_gpio_led is wrong.

| * intel-iommu: Fix tiny theoretical race in write-buffer flush.David Woodhouse2009-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In iommu_flush_write_buffer() we read iommu->gcmd before taking the register_lock, and then we mask in the WBF bit and write it to the register. There is a tiny chance that something else could have _changed_ iommu->gcmd before we take the lock, but after we read it. So we could be undoing that change. Never actually going to have happened in practice, since nothing else changes that register at runtime -- aside from the write-buffer flush it's only ever touched at startup for enabling translation, etc. But worth fixing anyway.

| * intel-iommu: Clean up handling of "caching mode" vs. IOTLB flushing.David Woodhouse2009-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As we just did for context cache flushing, clean up the logic around whether we need to flush the iotlb or just the write-buffer, depending on caching mode. Fix the same bug in qi_flush_iotlb() that qi_flush_context() had -- it isn't supposed to be returning an error; it's supposed to be returning a flag which triggers a write-buffer flush. Remove some superfluous conditional write-buffer flushes which could never have happened because they weren't for non-present-to-present mapping changes anyway.

| * intel-iommu: Clean up handling of "caching mode" vs. context flushing.David Woodhouse2009-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It really doesn't make a lot of sense to have some of the logic to handle caching vs. non-caching mode duplicated in qi_flush_context() and __iommu_flush_context(), while the return value indicates whether the caller should take other action which depends on the same thing. Especially since qi_flush_context() thought it was returning something entirely different anyway. This patch makes qi_flush_context() and __iommu_flush_context() both return void, removes the 'non_present_entry_flush' argument and makes the only call site which _set_ that argument to 1 do the right thing.

| * Intel IOMMU Pass Through SupportFenghua Yu2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds kernel parameter intel_iommu=pt to set up pass through mode in context mapping entry. This disables DMAR in linux kernel; but KVM still runs on VT-d and interrupt remapping still works. In this mode, kernel uses swiotlb for DMA API functions but other VT-d functionalities are enabled for KVM. KVM always uses multi level translation page table in VT-d. By default, pass though mode is disabled in kernel. This is useful when people don't want to enable VT-d DMAR in kernel but still want to use KVM and interrupt remapping for reasons like DMAR performance concern or debug purpose.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new stack is now recommended over the old one if used for industrial video (IIDC/DCAM) or for storage devices (SBP-2) due to better performance, improved compatibility, added features, and security. It should also be functionally on par with and is more secure than the old ieee1394 stack in the use case of consumer video devices. IP-over-1394 support for the new stack is currently emerging, and a backend of the firedtv DVB driver to the new stack should be available soon. The one remaining area where the old stack is still required are audio devices, as the new stack is not yet able to support the FFADO FireWire audio framework.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If isochronous contexts existed when firewire-ohci was unloaded, the core iso shutdown functions crashed with NULL dereferences, and buffers etc. weren't released. How the fix works: We first copy the card driver's iso shutdown hooks into the dummy driver, then fw_destroy_nodes notifies upper layers of devices going away, these should shut down (including their iso contexts), wait_for_completion(&card->done) will be triggered after upper layers gave up all fw_device references, after which the card driver's shutdown proceeds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decouple the creation and destruction of the net_device from the order of discovery and removal of nodes with RFC 2734 unit directories since there is no reliable order. The net_device is now created when the first RFC 2734 unit on a card is discovered, and destroyed when the last RFC 2734 unit on a card went away. This includes all remote units as well as the local unit, which is therefore tracked as a peer now too. Also, locking around the list of peers is slightly extended to guard against peer removal. As a side effect, fwnet_peer.pdg_lock has become superfluous and is deleted. Peer data (max_rec, speed, node ID, generation) are updated more carefully.

The 'mtdname' member of the private data structure is now allocated separately, but was not freed on certain error paths. Fix that, and make things simpler by _always_ allocating it separately so that we don't need 'if (mtdname != dev_name()) kfree(mtdname);'... which gets ugly now that we're doing it more than once, and more likely that we'll get it wrong some time.

It also adds concat support to physmap_of. This makes it possible to support e.g. the Intel P30 48F4400 chips which internally consists of 2 non-identical NOR chips on one die. Additionally partitions now can span over multiple chips. To describe such a chip's, multiple "reg" tuples are now supported in one flash device tree node. Here an dts example: flash@f0000000,0 { #address-cells = <1>; #size-cells = <1>; compatible = "cfi-flash"; reg = <0 0x00000000 0x02000000 0 0x02000000 0x02000000>; bank-width = <2>; partition@0 { label = "test-part1"; reg = <0 0x04000000>; }; }; Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
