pata_via: fix VT6410/6415/6330 detection issue

2010-04-01T23:02:15Z

commit bc8a67386fd462914269fa93446e1891955a8bb3 upstream. When using VT6410/6415/6330 chips on some VIA's platforms, the HDD connection to VT6410/6415/6330 cannot be detected. It is because the driver detects wrong via_isa_bridge ID, and then causes this issue to happen. Signed-off-by: Joseph Chan Signed-off-by: Jeff Garzik Signed-off-by: Greg Kroah-Hartman

GFS2: Skip check for mandatory locks when unlocking

2010-04-01T23:02:15Z

commit 720e7749279bde0d08684b1bb4e7a2eedeec6394 upstream. gfs2_lock() will skip locks on file which have mode set to 02666. This is a problem in cases where the mode of the file is changed after a process has obtained a lock on the file. Such a lock will be skipped and will result in a BUG in locks_remove_flock(). gfs2_lock() should skip the check for mandatory locks when unlocking a file.

classmate-laptop: use a single MODULE_DEVICE_TABLE to get correct aliases

2010-04-01T23:02:14Z

commit 02e77a55f7b7e36888e39c62439fedb90ae4e808 upstream. Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we create a table containing all ids to export to get a module alias for each one. This will fix automatic loading of the driver when one of the ACPI devices is not present (like the accelerometer, which is not present in some models).

x86: Fix sched_clock_cpu for systems with unsynchronized TSC

2010-04-01T23:02:14Z

commit 14be1f7454ea96ee614467a49cf018a1a383b189 upstream. On UV systems, the TSC is not synchronized across blades. The sched_clock_cpu() function is returning values that can go backwards (I've seen as much as 8 seconds) when switching between cpus. As each cpu comes up, early_init_intel() will currently set the sched_clock_stable flag true. When mark_tsc_unstable() runs, it clears the flag, but this only occurs once (the first time a cpu comes up whose TSC is not synchronized with cpu 0). After this, early_init_intel() will set the flag again as the next cpu comes up. Only set sched_clock_stable if tsc has not been marked unstable.

b43: Workaround circular locking in hw-tkip key update callback

2010-04-01T23:02:14Z

commit 96869a39399269a776a94812e9fff3d38b47d838 upstream The TKIP key update callback is called from the RX path, where the driver mutex is already locked. This results in a circular locking bug. Avoid this by removing the lock. Johannes noted that there is a separate bug: The callback still breaks on SDIO hardware, because SDIO hardware access needs to sleep, but we are not allowed to sleep in the callback due to mac80211's RCU locking.

Bluetooth: Fix kernel crash on L2CAP stress tests

2010-04-01T23:02:13Z

commit c2c77ec83bdad17fb688557b5b3fdc36661dd1c6 upstream. Added very simple check that req buffer has enough space to fit configuration parameters. Shall be enough to reject packets with configuration size more than req buffer.

Bluetooth: Fix potential bad memory access with sysfs files

2010-04-01T23:02:13Z

commit 101545f6fef4a0a3ea8daf0b5b880df2c6a92a69 upstream. When creating a high number of Bluetooth sockets (L2CAP, SCO and RFCOMM) it is possible to scribble repeatedly on arbitrary pages of memory. Ensure that the content of these sysfs files is always less than one page. Even if this means truncating. The files in question are scheduled to be moved over to debugfs in the future anyway.

ahci: use BIOS date in broken_suspend list

2010-04-01T23:02:13Z

commit 9deb343189b3cf45e84dd08480f330575ffe2004 upstream. HP is recycling both DMI_PRODUCT_NAME and DMI_BIOS_VERSION making ahci_broken_suspend() trigger for later products which are not affected by the original problems. Match BIOS date instead of version and add references to bko's so that full information can be found easier later.

quota: Fix warning when a delayed write happens before quota is enabled

2010-04-01T23:02:12Z

commit 0a5a9c725512461d19397490f3adf29931dca1f2 upstream. If a delayed-allocation write happens before quota is enabled, the kernel spits out a warning: WARNING: at fs/quota/dquot.c:988 dquot_claim_space+0x77/0x112() because the fact that user has some delayed allocation is not recorded in quota structure. Make dquot_initialize() update amount of reserved space for user if it sees inode has some space reserved. Also make sure that reserved quota space does not go negative and we warn about the filesystem bug just once. Signed-off-by: Jan Kara Signed-off-by: Greg Kroah-Hartman
