2008-03-24USB: new quirk flag to avoid Set-InterfaceAlan Stern
This patch (as1057) fixes a problem with the X-Rite/Gretag-Macbeth Eye-One Pro display colorimeter; the device crashes when it receives a Set-Interface request. A new quirk (USB_QUIRK_NO_SET_INTF) is introduced and a quirks entry is created for this device.

2008-03-24sata_promise: fix hardreset hotplug events, take 2Mikael Pettersson
A Promise SATA controller will signal hotplug events when a hard reset (COMRESET) is done on a port. These events aren't masked by the driver, and the unexpected interrupts will cause a sequence of failed reset attempts util libata's EH finally gives up. This has not been a common problem so far, but the pending libata hardreset-by-default changes makes it a critical issue. The solution is to disable hotplug events before a reset, and to reenable them afterwards. (Promise's driver does this too.) This patch adds SATA-specific versions of ->freeze() and ->thaw() that also disable and enable hotplug events. PATA ports continue to use the old versions of ->freeze() and ->thaw(). Accesses to the hotplug register must be serialised via host->lock. We rely on ap->lock == &ap->host->lock and that libata takes this lock before ->freeze() and ->thaw(). Document this requirement. The interrupt handler is adjusted so its hotplug register accesses are inside the region protected by host->lock. Tested on various chips (SATA300TX4, SATA300TX2plus, SATAII150TX4, FastTrack TX4000) with various combinations of SATA and PATA disks, with and without the pending hardreset-by-default changes.

This is minor, but dereferencing even current real_parent is not safe on debug kernels, since the memory, this points to, can be unmapped - RCU protection is required. Besides, the tgid field is deprecated and is to be replaced with task_tgid_xxx call (the 2nd patch), so RCU will be required anyway.

2008-03-24revert "kswapd should only wait on IO if there is IO"Andrew Morton
Revert commit f1a9ee758de7de1e040de849fdef46e6802ea117: Author: Rik van Riel <riel@redhat.com> Date: Thu Feb 7 00:14:08 2008 -0800 kswapd should only wait on IO if there is IO The current kswapd (and try_to_free_pages) code has an oddity where the code will wait on IO, even if there is no IO in flight. This problem is notable especially when the system scans through many unfreeable pages, causing unnecessary stalls in the VM. Additionally, tasks without __GFP_FS or __GFP_IO in the direct reclaim path will sleep if a significant number of pages are encountered that should be written out. This gives kswapd a chance to write out those pages, while the direct reclaim task sleeps.

Update documentation for the hw_random support to be current: - Documentation/hw_random.txt has been updated to reflect the current code: it's a framework now, a "core" with a small sysfs interface, that hardware-specific drivers plug in to. Text specific to Intel hardware is now at the end. - Kconfig now references the Documentation/hw_random.txt file and better explains what this really does. Both chunks of documentation now higlight the fact that the kernel entropy pool is maintained by "rngd", and this driver has nothing directly to do with that important task.

2008-03-24smackfs: remove redundant lock, fix open(,O_RDWR)Ahmed S. Darwish
Older smackfs was parsing MAC rules by characters, thus a need of locking write sessions on open() was needed. This lock is no longer useful now since each rule is handled by a single write() call. This is also a bugfix since seq_open() was not called if an open() O_RDWR flag was given, leading to a seq_read() without an initialized seq_file, thus an Oops. Signed-off-by: Ahmed S.

2008-03-24mm: fix boundary checking in free_bootmem_coreYinghai Lu
With numa enabled, some callers could have a range of memory on one node but try to free that on other node. This can cause some pages to be freed wrongly. For example: when we try to allocate 128g boot ram early for gart/swiotlb, and free that range later so gart/swiotlb can get some range afterwards. With this patch, we don't need to care which node holds the range, just loop to call free_bootmem_node for all online nodes. This patch makes free_bootmem_core() more robust by trimming the sidx and eidx according the ram range that the node has. And make the free_bootmem_core handle this out of range case. We could use bdata_list to make sure the range can be freed for sure. So next time, we don't need to loop online nodes and could use free_bootmem directly.

2008-03-24libata: assume no device is attached if both IDENTIFYs are abortedTejun Heo
This is to fix bugzilla #10254. QSI cdrom attached to pata_sis as secondary master appears as phantom device for the slave. Interestingly, instead of not setting DRQ after IDENTIFY which triggers NODEV_HINT, it aborts both IDENTIFY and IDENTIFY PACKET which makes EH retry. Modify EH such that it assumes no device is attached if both flavors of IDENTIFY are aborted by the device. There really isn't much point in retrying when the device actively aborts the commands. While at it, convert NODEV detection message to ata_dev_printk() to help debugging obscure detection problems. This problem was reported by Jan Bücken.

2008-03-24SVCRDMA: Use only 1 RDMA read scatter entry for iWARP adaptersRoland Dreier
The iWARP protocol limits RDMA read requests to a single scatter entry. NFS/RDMA has code in rdma_read_max_sge() that is supposed to limit the sge_count for RDMA read requests to 1, but the code to do that is inside an #ifdef RDMA_TRANSPORT_IWARP block. In the mainline kernel at least, RDMA_TRANSPORT_IWARP is an enum and not a preprocessor #define, so the #ifdef'ed code is never compiled. In my test of a kernel build with -j8 on an NFS/RDMA mount, this problem eventually leads to trouble starting with: svcrdma: Error posting send = -22 svcrdma : RDMA_READ error = -22 and things go downhill from there. The trivial fix is to delete the #ifdef guard. The check seems to be a remnant of when the NFS/RDMA code was not merged and needed to compile against multiple kernel versions, although I don't think it ever worked as intended. In any case now that the code is upstream there's no need to test whether the RDMA_TRANSPORT_IWARP constant is defined or not. Without this patch, my kernel build on an NFS/RDMA mount using NetEffect adapters quickly and 100% reproducibly failed with an error like: ld: final link failed: Software caused connection abort With the patch applied I was able to complete a kernel build on the same setup. (Tom Tucker says this is "actually an _ancient_ remnant when it had to compile against iWARP vs. non-iWARP enabled OFA trees.")

It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long".

2008-03-24[POWERPC] Fix Oops with TQM5200 on TQM5200Anatolij Gustschin
The "bestcomm-core" driver defines its of_match table as follows static struct of_device_id mpc52xx_bcom_of_match[] = { { .type = "dma-controller", .compatible = "fsl,mpc5200-bestcomm", }, { .type = "dma-controller", .compatible = "mpc5200-bestcomm", }, {}, }; so while registering the driver, the driver's probe function won't be called, because the device tree node doesn't have a device_type property. Thus the driver's bcom_engine structure won't be allocated. Referencing this structure later causes observed Oops. Checking bcom_eng pointer for NULL before referencing data pointed by it prevents oopsing, but fec driver still doesn't work (because of the lost bestcomm match and resulted task allocation failure). Actually the compatible property exists and should match and so the fec driver should work. This removes .type = "dma-controller" from the bestcomm driver's mpc52xx_bcom_of_match table to solve the problem.

This works around the problem by always using 4k pages for ioremap on pSeries (but not on other platforms).

2008-03-22[IPV4] fib_trie: fix warning from rcu_assign_poingerStephen Hemminger
This gets rid of a warning caused by the test in rcu_assign_pointer. I tried to fix rcu_assign_pointer, but that devolved into a long set of discussions about doing it right that came to no real solution. Since the test in rcu_assign_pointer for constant NULL would never succeed in fib_trie, just open code instead. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: Paul E.
