2008-04-07siimage: fix kernel oops on PPC 44xSergei Shtylyov
Fix kernel oops due to machine check occuring in init_chipset_siimage() on PPC 44x platforms. These 32-bit CPUs have 36-bit physical address and PCI I/O and memory spaces are mapped beyond 4 GB; arch/ppc/ code has a fixup in ioremap() that creates an illusion of the PCI I/O and memory resources being mapped below 4 GB, while arch/powerpc/ code got rid of this fixup with PPC 44x having instead CONFIG_RESOURCES_64BIT=y -- this causes the resources to be truncated to 32-bit 'unsigned long' type in this driver, and so non-existant memory being ioremap'ed and then accessed... Thanks to Valentine Barshak for providing an initial patch and explanations. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-07virtio_net: remove overzealous printkAnthony Liguori
The 'disable_cb' is really just a hint and as such, it's possible for more work to get queued up while callbacks are disabled. Under stress with an SMP guest, this printk triggers very frequently. There is no race here, this is how things are designed to work so let's just remove the printk.

2008-04-07virtio: remove overzealous BUG_ON.Rusty Russell
The 'disable_cb' callback is designed as an optimization to tell the host we don't need callbacks now. As it is not reliable, the debug check is overzealous: it can happen on two CPUs at the same time. Document this. Even if it were reliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped even on UP. Thanks to Balaji Rao for the bug report and testing.

2008-04-06fix IS_I9XX macro in i915 DRM driverJesse Barnes
Now that we're mapping registers in the DRM driver at load time, the driver actually checks the PCI ID, so we need to make sure the macros have all the right bits (and longer term use the DRM headers as the sole copy of the PCI & register definitions).

2008-04-06scsi: fix sense_slab/bio swapping livelockHugh Dickins
Since 2.6.25-rc7, I've been seeing an occasional livelock on one x86_64 machine, copying kernel trees to tmpfs, paging out to swap. Signature: 6000 pages under writeback but never getting written; most tasks of interest trying to reclaim, but each get_swap_bio waiting for a bio in mempool_alloc's io_schedule_timeout(5*HZ); every five seconds an atomic page allocation failure report from kblockd failing to allocate a sense_buffer in __scsi_get_command. __scsi_get_command has a (one item) free_list to protect against this, but rc1's [SCSI] use dynamically allocated sense buffer de25deb18016f66dcdede165d07654559bb332bc upset that slightly. When it fails to allocate from the separate sense_slab, instead of giving up, it must fall back to the command free_list, which is sure to have a sense_buffer attached. Either my earlier -rc testing missed this, or there's some recent contributory factor. One very significant factor is SLUB, which merges slab caches when it can, and on 64-bit happens to merge both bio cache and sense_slab cache into kmalloc's 128-byte cache: so that under this swapping load, bios above are liable to gobble up all the slots needed for scsi_cmnd sense_buffers below. That's disturbing behaviour, and I tried a few things to fix it. Adding a no-op constructor to the sense_slab inhibits SLUB from merging it, and stops all the allocation failures I was seeing; but it's rather a hack, and perhaps in different configurations we have other caches on the swapout path which are ill-merged. Another alternative is to revert the separate sense_slab, using cache-line-aligned sense_buffer allocated beyond scsi_cmnd from the one kmem_cache; but that might waste more memory, and is only a way of diverting around the known problem. While I don't like seeing the allocation failures, and hate the idea of all those bios piled up above a scsi host working one by one, it does seem to emerge fairly soon with the livelock fix. So lacking better ideas, stick with that one clear fix for now.

2008-04-04ipmi: change device node ordering to reflect probe orderCarol Hebert
In 2.6.14 a patch was merged which switching the order of the ipmi device naming from in-order-of-discovery over to reverse-order-of-discovery. So on systems with multiple BMC interfaces, the ipmi device names are being created in reverse order relative to how they are discovered on the system (e.g. on an IBM x3950 multinode server with N nodes, the device name for the BMC in the first node is /dev/ipmiN-1 and the device name for the BMC in the last node is /dev/ipmi0, etc.). The problem is caused by the list handling routines chosen in dmi_scan.c. Using list_add() causes the multiple ipmi devices to be added to the device list using a stack-paradigm and so the ipmi driver subsequently pulls them off during initialization in LIFO order. This patch changes the dmi_save_ipmi_device() list handling paradigm to a queue, thereby allowing the ipmi driver to build the ipmi device names in the order in which they are found on the system.

2008-04-04mtd: fix broken state in CFI driver caused by FL_SHUTDOWNAlexey Korolev
THe CFI driver in 2.6.24 kernel is broken. Not so intensive read/write operations cause incomplete writes which lead to kernel panics in JFFS2. We investigated the issue - it is caused by bug in FL_SHUTDOWN parsing code. Sometimes chip returns -EIO as if it is in FL_SHUTDOWN state when it should wait in FL_PONT (error in order of conditions). The following patch fixes the bug in state parsing code of CFI. Also I've added comments to notify developers if they want to add new case in future.

2008-04-04parport_pc: make sure to release IO ports after probing for IT87XXLinus Torvalds
Commit f63fd7e299ee13da071ecfce2b90b58c5e1562b1 ("parport_pc: detection for SuperIO IT87XX POST") only released the IO port region on success, not when the probe for the IT87XX chip failed. That caused not only a reserved region to leak, but also caused an oops when the driver module was unloaded and somebody tried to cat /proc/ioports - because the string that was assigned to the IO port region was a static string in the module virtual address area.

2008-04-04xen: fix grant table bugMichael Abd-El-Malek
fix memory corruption and crash due to mis-sized grant table. A PV OS has two grant table data structures: the grant table itself and a free list. The free list is composed of an array of pages, which grow dynamically as the guest OS requires more grants. While the grant table contains 8-byte entries, the free list contains 4-byte entries. So we have half as many pages in the free list than in the grant table. There was a bug in the free list allocation code. The free list was indexed as if it was the same size as the grant table. But it's only half as large. So memory got corrupted, and I was seeing crashes in the slab allocator later on.

2008-04-02USB: Allow initialization of broken keyspan serial adapters.Clark Rawlins
Fixes the keyspan driver after the addition of additional checking of driver requirements introduced in usb-serial.c commit 063a2da8f01806906f7d7b1a1424b9afddebc443. The initialization of the keyspan usb_serial_driver structs were not initializing the num_interrupt_out field and the additional checking was rejecting the end point so the driver wouldn't finish initializing. This commit initializes the fields to NUM_DONT_CARE. It works for the keyspan USA-49WG and doesn't break the USA-19HS which are the two keyspan devices I have to test with.

2008-04-02USB: fix bug in sg initialization in usbtestAlan Stern
This patch (as1062) fixes a bug in the scatter-gather initialization code in the usbtest driver. When the sg-helper conversion was performed, it wasn't done correctly.

2008-04-02USB: serial: fix regression in Visor/Palm OS module for kernels >= 2.6.24Brad Sawatzky
Fixes a bug/inconsistency revealed by the additional sanity checking in commit 063a2da8f01806906f7d7b1a1424b9afddebc443 introduced in the original 2.6.24 branch. The Handspring Visor / PalmOS 4 device structure defines .num_bulk_out=2 but the usb-serial probe returns num_bulk_out=3, triggering the check in the above commit and forcing a bail out when the device (a Garmin iQue in my case) attempts to connect. The patch bumps the expected number of endpoints to 3. FWIW, this patch will probably solve the following kernel bug report for Treo users (identical symptoms, different model PalmOS units): <http://bugzilla.kernel.org/show_bug.cgi?id=10118> Signed-off-by: Brad Sawatzky <brad+kernel@swatter.net> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-04-02USB: serial: ti_usb_3410_5052: Correct TUSB3410 endpoint requirements.Robert Spanton
The changes introduced in commit 063a2da8f01806906f7d7b1a1424b9afddebc443 changed the semantics of the num_interrupt_in, num_interrupt_out, num_bulk_in and num_bulk_out entries of the usb_serial_driver struct to be the number of endpoints the device has when probed. This patch changes the ti_1port_device usb_serial_driver struct to reflect this change. The single port devices only have 1 bulk_out endpoint in their initial configuration, and so this patch changes the number of other types to NUM_DONT_CARE. The same change probably needs doing to the ti_2port_device struct, but I don't have a two port device at hand.

2008-04-02USB: another ehci_iaa_watchdog fixDavid Brownell
This patch, suggested by Alan Stern, fixes the hung USB issues on my notebook from suspend/resume cycles. It does so by eliminating some confusion about the internal state machine associated with unlinking from the EHCI async schedule ring, which caused a recent regression: http://bugzilla.kernel.org/show_bug.cgi?id=10345 Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Use ->ata_input_data method instead of calling ata_input_data() directly. Currently it matters only for (broken) ide-cris host driver but it may change in the future. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
