* USB: EHCI: fix counting of transaction error retriesAlan Stern2009-08-082-5/+5
| | | | | | | | | | | | | | | This patch (as1274) simplifies the counting of transaction-error retries. Now we will count up from 0 to QH_XACTERR_MAX instead of down from QH_XACTERR_MAX to 0. The patch also fixes a small bug: qh->xacterr was not getting initialized for interrupt endpoints.

* USB: EHCI: fix two new bugs related to Clear-TT-BufferAlan Stern2009-08-082-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1273) fixes two(!) bugs introduced by the new Clear-TT-Buffer implementation in ehci-hcd. It is now possible for an idle QH to have some URBs on its queue -- this will happen if a Clear-TT-Buffer is pending for the QH's endpoint. Consequently we should not issue a warning when someone tries to unlink an URB from an idle QH; instead we should process the request immediately. The refcounts for QHs could get messed up, because submit_async() would increment the refcount when calling qh_link_async() and qh_link_async() would then refuse to link the QH into the schedule if a Clear-TT-Buffer was pending. Instead we should increment the refcount only when the QH actually is added to the schedule. The current code tries to be clever by leaving the refcount alone if an unlink is immediately followed by a relink; the patch changes this to an unconditional decrement and increment (although they occur in the opposite order).

| | | | | | | | | | | | | | | | | | OMAP3EVM uses ISP1504 phy which doesn't require any programming and thus has to use NOP otg transceiver.

* USB: devio: Properly do access_ok() checksMichael Buesch2009-08-081-3/+5
| | | | | | | | | | | | | | | | access_ok() checks must be done on every part of the userspace structure that is accessed. If access_ok() on one part of the struct succeeded, it does not imply it will succeed on other parts of the struct. (Does depend on the architecture implementation of access_ok()). This changes the __get_user() users to first check access_ok() on the data structure.

* USB: pl2303: New vendor and product idKhanh-Dang Nguyen Thu Lam2009-08-082-0/+5
| | | | | | | | | | | | | | | | I am submitting a patch for the pl2303 driver. This patch adds support for the "Sony QN-3USB" cable (vendor=0x054c, product=0x0437). This USB cable is a so-called data cable used to connect a Sony mobile phone to a computer. Supported models are Sony CMD-J5, J6, J7, J16, J26, J70 and Z7. I have used this patch with my Sony CMD-J70 for several days and I haven't encountered any kernel/hardware issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is in the gpio banks range is reversed.

The TS-7200 models all have 16-bit NOR flash. Update the platform init to support this. Remove the private TS72XX_NOR_* defines and use the common ep93xx defines for the external chip select physical base address instead. Move the NOR flash registration into a static __init function. When the NAND flash support is updated this function will also be used to register the NAND flash for the TS-7250 and TS-7260.

This is a side-effect of: dev_unicast_init(dev); in alloc_netdev_mq() making use of dev->addr_list_lock. The device has just been allocated freshly, it's not accessible anywhere yet so no locking is needed at all - in fact it's wrong to lock it here (the lock isnt initialized yet).

To allow these checks, store the machine flags in the lowcore when the machine type has been detected. Moving the machine_flags to the lowcore has been introduced with git commit 25097bf153391f7be4c591d47061b3dc4990dac2 Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

So it is possible to get a random value. 2. One line added by commit 2c2e2c38("IOMMU Identity Mapping Support") change the code path, let it bypass domain_update_iommu_cap(), as well as missing the increment of domain iommu reference count. The latter is also likely to cause a leak of domains on repeated VMM assignment and deassignment.

This means that on IA64 we correctly round up to the MM page size, not just to the VT-d page size. Also remove the incorrect mm_to_dma_pfn() when intel_map_sg() calls domain_sg_mapping() -- the 'size' variable is in VT-d pages already.
