* USB: usb-storage: don't clear-halt when Get-Max-LUN stallsAlan Stern2008-02-212-11/+12
| | | | | | | | | | | | | | | | | This patch (as1032) removes the Clear-Halt calls in usb_stor_Bulk_max_lun(). Evidently some devices (such as the Oracom MP3 player) really don't like to receive these requests when their bulk endpoints aren't halted. The only reason for adding them originally was to get an ancient ZIP-100 drive to work. But since this device has only a single LUN, we don't need to send it a Get-Max-LUN request at all. Adding an unusual_devs entry for the ZIP-100 with the SINGLE_LUN flag set will cause this step to be skipped.

* USB: fix previous sparse fix which was incorrectDavid Brownell2008-02-211-12/+12
| | | | | | | | | | | | | The previous fix for a "sparse" warning in ehci_urb_dequeue() was incorrect. After rescheduling interrupt transfers it returned the URB's completion status, not status for the dequeue operation itself. This patch resolves that issue, cleans up the code in the reschedule path, and shrinks the object code by a dozen bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several AGP drivers right now use ioremap_nocache() on kernel ram in order to turn a page of regular memory uncached. There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

It may return earlier if an error occurs, but not if everything is ok. This large timeout value became visible with commit dfa77f611ff295598e218aa0eb6efa73a5cf26d0 "qdio: set QDIO_ACTIVATE_TIMEOUT to 5s", which intended to fix the timeout value which was zero. In turn setting an FCP adapter online took 5 seconds. In practice waiting for 5ms before continuing is sufficient as pointed out by Utz Bacher and Cornelia Huck.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After setting the status of the cqr and releasing the lock for the block cqr queue, we call the cqr callback function, which will usually just trigger the dasd_block_tasklet. But when the tasklet is already running the cqr might be processed before we invoke the callback function. In rare cases the callback pointer may already be invalid by the time we want to call it, which will result in a panic. Solution: Call the callback function first and then release the lock.

It also adjusts the size lengths in the atapi code to add the drain buffer to the DMA length so the driver knows it can rely on it. I suspect I should also be checking for AHCI as well as ATA_DEV_ATAPI, but I couldn't see how to do that easily. tj: * atapi_drain_needed() added such that draining is applied to only misc ATAPI commands. * q->bounce_gfp used when allocating drain buffer. * Now duplicate ATAPI PIO drain logic dropped. * ata_dev_printk() used instead of sdev_printk().
