* | gru: fix automatic retry of gru instruction failuresJack Steiner2009-06-181-3/+2
| | | | | | | | | | | | | | | | | | Fix bug in automatic retry of GRU instruction failures. CBR substatus (message queue failure) was being checked incorrectly.

* | gru: add user request to explicitly unload a gru contextJack Steiner2009-06-183-28/+41
| | | | | | | | | | | | | | | | | | | | | | | | Add user function to explicitly unload GRU kernel contexts from the GRU. Only contexts that are not in-use will be unloaded. This function is primarily for testing. It is not expected that this will be used in normal production systems.

* | gru: fix cache coherency issues with instruction retryJack Steiner2009-06-184-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix two problems related to GRU instruction failures. Cache coherency is not maintained for CBEs except when loading or unloading contexts. When reading a CBE to extract error information, the CBE must first be flushed from the cache. The function that reads kerrnel CBEs was reading the wrong CBE.

* | kexec: sysrq: simplify sysrq-c handlerNeil Horman2009-06-181-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the sysrq-c handler is bit over-engineered. Its behavior is dependent on a few compile time and run time factors that alter its behavior which is really unnecessecary. If CONFIG_KEXEC is not configured, sysrq-c, crashes the system with a NULL pointer dereference. If CONFIG_KEXEC is configured, it calls crash_kexec directly, which implies that the kexec kernel will either be booted (if its been previously loaded), or it will simply do nothing (the no kexec kernel has been loaded). It would be much easier to just simplify the whole thing to dereference a NULL pointer all the time regardless of configuration. That way, it will always try to crash the system, and if a kexec kernel has been loaded into reserved space, it will still boot from the page fault trap handler (assuming panic_on_oops is set appropriately).

* | w1-gpio: add external pull-up enable callbackDaniel Mack2009-06-181-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On embedded devices, sleep mode conditions can be tricky to handle, Especially when processors tend to pull-down the w1 bus during sleep. Bus slaves (such as the ds2760) may interpret this as a reason for power-down conditions and entirely switch off the device. This patch adds a callback function pointer to let users switch on and off the external pull-up resistor. This lets the outside world know whether the processor is currently actively driving the bus or not. When this callback is not provided, the code behaviour won't change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On OpenFirmware platforms, it makes the most sense to get platform_data from the device tree. Make an attempt to translate OF node properties into platform_data struct before bailing out. Note that the implementation approach taken differs from other device drivers that make use of device tree information. This is because I2C chips are already registered automatically by of_i2c, so we can get by with a small translator function in the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RTC driver for ds1742 / ds1743 uses a static nvram attribute. This patch replaces this static attribute with one nvram attribute for each ds174x registered. The nvram size is not the same for all types of ds174x. The nvram size is accessible as the file size of the nvram attribute in sysfs. With only a single nvram attribute, this file size will be incorrect if more than one type of ds174x is present on a system. See the comment in the removed code below.

* | spi: move more spi_setup() functionality into coreDavid Brownell2009-06-1815-115/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move some common spi_setup() error checks into the SPI framework from the spi_master controller drivers: - Add a new "mode_bits" field to spi_master - Use that in spi_setup to validate the spi->mode value being requested. Setting this new field is now mandatory for any controller supporting more than vanilla SPI_MODE_0. - Update all spi_master drivers to: * Initialize that field * Remove current spi_setup() checks using that value. This is a net minor code shrink.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Start moving some spi_setup() functionality into the SPI core from the various spi_master controller drivers: - Make that function stop being an inline; - Move two common idioms from drivers into that new function: * Default bits_per_word to 8 if that field isn't set * Issue a standardized dev_dbg() message This is a net minor source code shrink, and supports enhancments found in some follow-up patches.

| | | | | | | | | | | | | | | | | | | | Instead of starting from the iomem or ioport roots, start from the parent bus' resources. This fixes a bug where child resources would appear above their parents resources if they had the same size.

Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.
