2009-01-17move wm8400-regulator's probe function to .devinit.textUwe Kleine-König1-1/+1
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.

2009-01-16IB/mlx4: Fix memory ordering problem when posting LSO sendsRoland Dreier1-9/+19
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>.

2009-01-16Btrfs: fix ioctl arg size (userland incompatible change!)Chris Mason2-7/+10
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 Mason1-0/+1
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>

2009-01-16Revert "PCI PM: Register power state of devices during initialization"Linus Torvalds1-6/+2
This reverts commit 98e6e286d7b01deb7453b717aa38ebb69d6cefc0, as Yinghai Lu reports that it breaks kexec with at least the e1000 and e1000e drivers. The reason is that the shutdown sequence puts the hardware into D3 sleep, and the commit causes us to claim that it then is in D0 (running) state just because we don't understand the PM capabilities. Which then later makes "pci_set_power_state()" not do anything, and the device never wakes up properly and just returns 0xff to everything.

2009-01-16drm: initial KMS config fixesJesse Barnes3-36/+95
When mode setting is first initialized, the driver will call into drm_helper_initial_config() to set up an initial output and framebuffer configuration. This routine is responsible for probing the available connectors, encoders, and crtcs, looking for modes and putting together something reasonable (where reasonable is defined as "allows kernel messages to be visible on as many displays as possible"). However, the code was a bit too aggressive in setting default modes when none were found on a given connector. Even if some connectors had modes, any connectors found lacking modes would have the default 800x600 mode added to their mode list, which in some cases could cause problems later down the line. In my case, the LVDS was perfectly available, but the initial config code added 800x600 modes to both of the detected but unavailable HDMI connectors (which are on my non-existent docking station). This ended up preventing later code from setting a mode on my LVDS, which is bad. This patch fixes that behavior by making the initial config code walk through the connectors first, counting the available modes, before it decides to add any default modes to a possibly connected output. It also fixes the logic in drm_target_preferred() that was causing zeroed out modes to be set as the preferred mode for a given connector, even if no modes were available.

2009-01-16hvc_console: Remove tty->low_latencyHendrik Brueckner1-2/+0
This patch removes the tty->low_latency setting. For irq based hvc_console backends the tty->low_latency must be set to 0, because the tty_flip_buffer_push() function must not be called from IRQ context (see drivers/char/tty_buffer.c). For polled backends, the low_latency setting causes the bug trace below, because tty_flip_buffer_push() is called within an atomic context and subsequent calls might sleep due to mutex_lock.
