2009-01-17oprofile: fix uninitialized use of struct op_entryRobert Richter
Impact: fix crash In case of losing samples struct op_entry could have been used uninitialized causing e.g. a wrong preemption count or NULL pointer access. This patch fixes this. Signed-off-by: Robert Richter <robert.richter@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-17move wm8400-regulator's probe function to .devinit.textUwe Kleine-König
A pointer to wm8400_regulator_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

ehca_plpar_hcall9() takes an unsigned long array, so make all callers pass that in.

2009-01-16rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().Rami Rosen
When running modprobe rt73usb, and then rmmod rt73usb, and then iwconfig, the wlan0 device does not disappear. When repeating this process again, we get a kernel Oops errors and "BUG: unable to handle kernel paging request..." message in the kernel log. The reason for this is that there is an error in rt2x00rfkill_free(), which is called in the process of removing the device (rt2x00lib_remove_dev() in rt2x00dev.c). rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is bit number 1 () in rt2x00dev->flags instead of in rt2x00dev->rfkill_state. As a result, when checking the DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call ieee80211_unregister_hw(). This patch corrects this: the parameter for __test_and_clear_bit() in rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not &rt2x00dev->flags.

2009-01-16cfg80211: Fix regression with 11d on bandsLuis R. Rodriguez
This fixes a regression on disallowing bands introduced with the new 802.11d support. The issue is that IEEE-802.11 allows APs to send a subset of what a country regulatory domain defines. This was clarified in this document: http://tinyurl.com/11d-clarification As such it is possible, and this is what is done in practice, that a single band 2.4 GHz AP will only send 2.4 GHz band regulatory information through the 802.11 country information element and then the current intersection with what CRDA provided yields a regulatory domain with no 5 GHz information -- even though that country may actually allow 5 GHz operation. We correct this by only applying the intersection rules on a channel if the the intersection yields a regulatory rule on the same band the channel is on. Signed-off-by: Luis R.

In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need to remove the CMD_WANT_SKB flag from the TX cmd queue.

2009-01-16PCI PM: Restore standard config registers of all devices earlyRafael J. Wysocki
There is a problem in our handling of suspend-resume of PCI devices that many of them have their standard config registers restored with interrupts enabled and they are put into the full power state with interrupts enabled as well. This may lead to the following scenario: * an interrupt vector is shared between two or more devices * one device is resumed earlier and generates an interrupt * the interrupt handler of another device tries to handle it and attempts to access the device the config space of which hasn't been restored yet and/or which still is in a low power state * the system crashes as a result To prevent this from happening we should restore the standard configuration registers of all devices with interrupts disabled and we should put them into the D0 power state right after that. Unfortunately, this cannot be done using the existing pci_set_power_state(), because it can sleep. Also, to do it we have to make sure that the config spaces of all devices were actually saved during suspend. Signed-off-by: Rafael J.

2009-01-16IB/mlx4: Fix memory ordering problem when posting LSO sendsRoland Dreier
The current work request posting code writes the LSO segment before writing any data segments. This leaves a window where the LSO segment overwrites the stamping in one cacheline that the HCA prefetches before the rest of the cacheline is filled with the correct data segments. When the HCA processes this work request, a local protection error may result. Fix this by saving the LSO header size field off and writing it only after all data segments are written. This fix is a cleaned-up version of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1383>.

2009-01-16quota: Improve lockingJan Kara
We implement dqget() and dqput() that need neither dqonoff_mutex nor dqptr_sem. Then move dqget() and dqput() calls so that they are not called from under dqptr_sem. This is important because filesystem callbacks aren't called from under dqptr_sem which used to cause *lots* of problems with lock ranking (and with OCFS2 they became close to unsolvable). The patch also removes two functions which were introduced solely because OCFS2 needed them to cope with the old locking scheme. As time showed, they were not enough for OCFS2 anyway and it would be unnecessary work to adapt them to the new locking scheme in which they aren't needed. As a result OCFS2 needs the following patch to compile properly with quotas. Sorry to any bisecters which hit this in advance. Signed-off-by: Jan Kara <jack@suse.cz>
2009-01-16Btrfs: fix ioctl arg size (userland incompatible change!)Chris Mason
The structure used to send device in btrfs ioctl calls was not properly aligned, and so 32 bit ioctls would not work properly on 64 bit kernels. We could fix this with compat ioctls, but we're just one byte away and it doesn't make sense at this stage to carry about the compat ioctls forever at this stage in the project. This patch brings the ioctl arg up to an evenly aligned 4k. Signed-off-by: Chris Mason <chris.mason@oracle.com>
2009-01-16Btrfs: Clear the device->running_pending flag before bailing on congestionChris Mason
Btrfs maintains a queue of async bio submissions so the checksumming threads don't have to wait on get_request_wait. In order to avoid extra wakeups, this code has a running_pending flag that is used to tell new submissions they don't need to wake the thread. When the threads notice congestion on a single device, they may decide to requeue the job and move on to other devices. This makes sure the running_pending flag is cleared before the job is requeued. It should help avoid IO stalls by making sure the task is woken up when new submissions come in. Signed-off-by: Chris Mason <chris.mason@oracle.com>

Otherwise it can be very confusing to find a "EXT3-fs: " failure in the middle of EXT4-fs failures, and it makes it harder to track the source of the failure. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
