2009-02-06ACPICA: Allow multiple backslash prefix in namepathsLin Ming
commit d037c5fd7367548191eab2b376a1d08c4ffaf7ff upstream. In a fully qualified namepath, allow multiple backslash prefixes. This can happen because of the use of a double-backslash in strings (since backslash is the escape character) causing confusion.

2009-02-06sata_mv: Fix chip type for Hightpoint RocketRaid 1740/1742Mark Lord
commit 4462254ac6be9150aae87d54d388fc348d6fcead upstream. Fix chip type for the Highpoint RocketRAID 1740 and 1742 PCI cards. These really do have Marvell 6042 chips on them, rather than the 5081 chip. Confirmed by multiple (two) users (for the 1740), and by examining the product photographs from Highpoint's web site.

2009-02-06ACPI: Do not modify SCI_EN directlyRafael J. Wysocki
commit 11e93130c7ce5228d484fd5e86f3984835d4256b upstream. According to the ACPI specification the SCI_EN flag is controlled by the hardware, which sets this flag to inform the kernel that ACPI is enabled. For this reason, we shouldn't try to modify SCI_EN directly. Also, we don't need to do it in irqrouter_resume(), since lower-level resume code takes care of enabling ACPI in case it hasn't been enabled by the BIOS before passing control to the kernel (which by the way is against the ACPI specification).

commit 816bb611e41be29b476dc16f6297eb551bf4d747 upstream Add decaying history of predicted idle time, instead of using the last early wakeup. This logic helps menu governor do better job of predicting idle time.

2009-02-06p54usb: rewriting rx/tx routines to make use of usb_anchor's facilitiesChristian Lamparter
commit dd397dc9dddfa2149a1bbc9e52ac7d5630737cec upstream Alan Stern found several flaws in p54usb's implementation and annotated: "usb_kill_urb() and similar routines do not expect an URB's completion routine to deallocate it. This is almost obvious -- if the URB is deallocated before the completion routine returns then there's no way for usb_kill_urb to detect when the URB actually is complete." This patch addresses all known limitations in the old implementation and fixes khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

2009-02-06Fix memory corruption in console selectionMikulas Patocka
commit 878b8619f711280fd05845e21956434b5e588cc4 upstream. Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.

2009-02-06fbdev/atyfb: Fix DSP config on some PowerMacs & PowerBooksRisto Suominen
commit 7fbb7cadd062baf299fd8b26a80ea99da0c3fe01 upstream. Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500 and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable columns in their framebuffer image. This seems to depend on a value (4) read from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to be written to the chip. This patch uses a value calculated by aty_init_pll_ct instead, as a starting point. There are questions as to whether this should be extended to other platforms or maybe made dependent on specific chip types, but in the meantime, this has been tested on various powermacs and works for them so let's commit it.

2009-02-02USB: fix char-device disconnect handlingAlan Stern
commit 501950d846218ed80a776d2aae5aed9c8b92e778 upstream. This patch (as1198) fixes a conceptual bug: Somewhere along the line we managed to confuse USB class devices with USB char devices. As a result, the code to send a disconnect signal to userspace would not be built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were disabled. The usb_fs_classdev_common_remove() routine has been renamed to usbdev_remove() and it is now called whenever any USB device is removed, not just when a class device is unregistered. The notifier registration and unregistration calls are no longer conditionally compiled. And since the common removal code will always be called as part of the char device interface, there's no need to call it again as part of the usbfs interface; thus the invocation of usb_fs_classdev_common_remove() has been taken out of usbfs_remove_device().

2009-02-02USB: usbmon: Implement compat_ioctlPete Zaitcev
commit 7abce6bedc118eb39fe177c2c26be5d008505c14 upstream. Running a 32-bit usbmon(8) on 2.6.28-rc9 produces the following: ioctl32(usbmon:28563): Unknown cmd fd(3) cmd(400c9206){t:ffffff92;sz:12} arg(ffd3f458) on /dev/usbmon0 It happens because the compatibility mode was implemented for 2.6.18 and not updated for the fsops.compat_ioctl API. This patch relocates the pieces from under #ifdef CONFIG_COMPAT into compat_ioctl with no other changes except one new whitespace.

2009-02-02USB: fix toggle mismatch in disable_endpoint pathsAlan Stern
commit ddeac4e75f2527a340f9dc655bde49bb2429b39b upstream. This patch (as1200) finishes some fixes that were left incomplete by an earlier patch. Although nobody has addressed this issue in the past, it turns out that we need to distinguish between two different modes of disabling and enabling endpoints. In one mode only the data structures in usbcore are affected, and in the other mode the host controller and device hardware states are affected as well. The earlier patch added an extra argument to the routines in the enable_endpoint pathways to reflect this difference. This patch adds corresponding arguments to the disable_endpoint pathways. Without this change, the endpoint toggle state can get out of sync between the host and the device. The exact mechanism depends on the details of the host controller (whether or not it stores its own copy of the toggle values).

commit 46a5f173fc88ffc22651162033696d8a9fbcdc5c upstream. When CONFIG_DMI is not enabled, dmi detection should flag that no board could be detected (err=1) rather than another error condition (err<0).

2009-01-24USB: re-enable interface after driver unbindsAlan Stern
commit 2caf7fcdb8532045680f06b67b9e63f0c9613aaa upstream. This patch (as1197) fixes an error introduced recently. Since a significant number of devices can't handle Set-Interface requests, we no longer call usb_set_interface() when a driver unbinds from an interface, provided the interface is already in altsetting 0. However the interface still does get disabled, and the call to usb_set_interface() was the only thing re-enabling it. Since the interface doesn't get re-enabled, further attempts to use it fail. So the patch adds a call to usb_enable_interface() when a driver unbinds and the interface is in altsetting 0. For this to work right, the interface's endpoints have to be re-enabled but their toggles have to be left alone. Therefore an additional argument is added to usb_enable_endpoint() and usb_enable_interface(), a flag indicating whether or not the endpoint toggles should be reset. This is a forward-ported version of a patch which fixes Bugzilla #12301.

2009-01-24usb-storage: set CAPACITY_HEURISTICS flag for bad vendorsAlan Stern
commit a81a81a25d3ecdab777abca87c5ddf484056103d upstream. This patch (as1194b) makes usb-storage set the CAPACITY_HEURISTICS flag for all devices made by Nokia, Nikon, or Motorola. These companies seem to include the READ CAPACITY bug in all of their devices. Since cell phones and digital cameras rely on flash storage, which always has an even number of sectors, setting CAPACITY_HEURISTICS shouldn't cause any problems. Not even if the companies wise up and start making devices without the bug. A large number of unusual_devs entries are now unnecessary, so the patch removes them.

2009-01-24usb-storage: add last-sector hacksAlan Stern
commit 25ff1c316f6a763f1eefe7f8984b2d8c03888432 upstream. This patch (as1189c) adds some hacks to usb-storage for dealing with the growing problems involving bad capacity values and last-sector accesses: A new flag, US_FL_CAPACITY_OK, is created to indicate that the device is known to report its capacity correctly. An unusual_devs entry for Linux's own File-backed Storage Gadget is added with this flag set, since g_file_storage always reports the correct capacity and since the capacity need not be even (it is determined by the size of the backing file). An entry in unusual_devs.h which has only the CAPACITY_OK flag set shouldn't prejudice libusual, since the device will work perfectly well with either usb-storage or ub. So a new macro, COMPLIANT_DEV, is added to let libusual know about these entries. When a last-sector access fails three times in a row and neither the FIX_CAPACITY nor the CAPACITY_OK flag is set, we assume the last-sector bug is present. We replace the existing status and sense data with values that will cause the SCSI core to fail the access immediately rather than retry indefinitely. This should fix the difficulties people have been having with Nokia phones. This version of the patch differs from the version accepted into the mainline only in that it does not trigger a WARN() when an odd-numbered last-sector access succeeds. In a stable kernel series we don't want to go around spamming users' logs and consoles for no good reason.

2009-01-24sgi-xp: eliminate false detection of no heartbeatDean Nelson
commit 158bc69effbf96f59c01cdeb20f8d4c184e59f8e upstream. After XPC has been up and running on multiple partitions for any length of time, if XPC on one of the partitions is stopped and restarted (either by a rmmod/insmod or a system restart), it is possible for the XPCs running on the other partitions to falsely detect a lack of heartbeat from the XPC that was just restarted. This false detection will occur if the restarted XPC comes up within the five-seconds preceding one of the other XPC's heartbeat check (which occurs once every twenty seconds). The detection of no heartbeat results in the detecting XPC deactivating from the just restarted XPC. The only remedy is to restart one of the XPCs and hope that one doesn't hit this five-second window on any of the other partitions.
