dma_sync_single() and dma_sync_sg() have been described as "Backwards compat, remove in 2.7.x" for a long time (since 2.6.5). This marks dma_sync_single() and dma_sync_sg() as deprecated so the users get notified before removing them. Signed-off-by:

In moxa.c there are 32 minor numbers reserved for each device. The number of ports actually available per device is stored in moxa_board_conf->numPorts. This number is not considered in moxa_open(). Opening a port that is not available results in a kernel oops. This patch adds a test to moxa_open() that prevents opening unavailable ports.

The remove member of the pci_driver stli_pcidriver uses __devexit_p(), so the remove function itself should be marked with __devexit. Even more so considering the probe function is marked with __devinit. Signed-off-by:

The bug is ancient. If we trace the sub-thread of our natural child and this sub-thread exits, we update parent->signal->cxxx fields. But we should not do this until the whole thread-group exits, otherwise we account this thread (and all other live threads) twice. Add the task_detached() check. No need to check thread_group_empty(), wait_consider_task()->delay_group_leader() already did this. Signed-off-by:

The rtc_update_irq() might be called with irqs enabled, if a interrupt handler was registered without IRQF_DISABLED. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock. Also update kerneldoc and drivers which do extra work to follow the current interface spec, as suggestted by David Brownell. Signed-off-by:

Since we renamed the file, we might want to rename the file internals too. Though we don't bother with changing platform driver name and platform module alias. The stuff is legacy and hopefully we'll remove it soon. Suggested-by:

Anton Vorontsov authored
mpc83xx_spi_work() is quite large, with up to five indentation levels and is quite difficult to read. So, split the function in two parts: 1. mpc83xx_spi_work() now only traverse queued spi messages; 2. mpc83xx_spi_do_one_msg() only manages single messages. There should be no functional changes.

This is needed for some underlaying GPIO controllers that may be a bit slow, or if chip-select signal need some time to stabilize. For what it's worth, we already have the similar delay for chip-select de-assertion case. Signed-off-by:

When a platform is running at high frequencies it's not always possible to scale-down a frequency to a requested value, and using mmc_spi driver this leads to the following printk flood during card polling: ... mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. ... Fix this by using WARN_ONCE(), it's better than the flood, and also better than turning dev_err() into dev_dbg(), since we actually want to warn that some things may not work correctly.

With this patch we'll able to select spi_mpc83xx driver on the MPC86xx platforms. Let the driver depend on FSL_SOC, so we don't have to worry about Kconfig anymore. Also remove the "experimental" dependency, the driver has been tested to work on a various hardware, and surely not experimental anymore. Signed-off-by:

Rodolfo Giometti authored
This patch adds the kernel side of the PPS support currently named "LinuxPPS". PPS means "pulse per second" and a PPS source is just a device which provides a high precision signal each second so that an application can use it to adjust system clock time. Common use is the combination of the NTPD as userland program with a GPS receiver as PPS source to obtain a wallclock-time with sub-millisecond synchronisation to UTC. To obtain this goal the userland programs shoud use the PPS API specification (RFC 2783 - Pulse-Per-Second API for UNIX-like Operating Systems, Version 1.0) which in part is implemented by this patch. It provides a set of chars devices, one per PPS source, which can be used to get the time signal. The RFC's functions can be implemented by accessing to these char devices. Signed-off-by:

Fix potential SGI GRU bug that could cause a use-after-free. If one thread in a task is flushing the GRU and another thread destroys the GRU context, there is the potential to access a table after it has been freed.
